PowerPlus Technology
MOONS’ PowerPlus technology provides 25% to 40% more torque across the entire speed range of the
motor. The increased torque is a result of higher motor efficiency, and is available without increasing the
drive voltage or current.
Typical Applications:
Machine Upgrades: Changing existing machines to PowerPlus motors can be a quick path to new
models with improved performance. Because the motor, drive and mechanical parts remain the same,
benefits include:
Faster new product introduction
Reduced engineering costs
Easy production phase in
Reduced spare parts inventory
Correct stalling problems with existing machines:
Problems with occasional machine stalling are often due to unexpected field conditions such as: low
temperature, dirt, and customers using machines in unexpected ways. Using PowerPlus motors can be
a quick effective solution.
Overcome drive or power supply limitations in new designs:
Often a higher current drive or higher voltage power supply can provide needed extra torque. However, in
many designs the drive current cannot be increased without changing to a substantially more expensive
drive. And increasing drive voltage can be impractical, expensive, or may not be allowed for safety
reasons. In these cases using PowerPlus motors can be especially useful.
Conventional Motor PowerPlus Technology
Some of the torque
producing magnetic
flux that links the rotor
to the stator is outside
the stator teeth. This
stray flux adds little to
motor torque.
Magnets placed
between the stator
teeth redirect most
of the stray magnetic
flux into the stator
teeth. This produces
additional torque with
the same input power.

Encapsulated Motors
Encapsulation Technology From MOONS' Offers Many Advantages
Ideal for Security Cameras
In addition to all the advantages of normal step motors, these new encapsulated motors can help
achieve a breakthrough in miniaturization of security cameras. Small step motors are a core component
in security camera systems. With MOONS’ encapsulation technology, the 36mm diameter motor is now
available with a thickness as little as 12.8mm.
Low Temperature Rise
The winding resistance of these new motors is nearly 30% lower than other motors with the same
thickness and output-torque. In addition, the new encapsulation technology increases the heat-
conducting property of these motors. The lower winding resistance and improved thermal conductivity
combine to drastically lower the temperature of these motors to less than 80% of standard motors.
35% More Torque
Lower resistance coils allows these
encapsulated motors to handle more power.
With the same temperature rise. These
motors can produce 35% more torque.
Quieter & Smoother
New materials and improved manufacturing processes,
means these motors have a higher precision, more stable
design. This controls vibration and reduces noise. It also
makes the motor run smoothly.
More Load & Longer Life
MOONS’ encapsulated stepping motors use large bearings that can handle large axial and radial loads,
ensure long life.
RoHS
Encapsulated stepping motors are RoHS compliant.
Molded Construction
Encapsulated winding Runs cooler – Longer life
Better sealing Longer life

2 Phase and 3 Phase Motors
MOONS’ offers several families of hybrid step motors with a different number of phases and step angles.
Each has a combination of advantages that are better suited to specific applications.
2 Phase - 1.8 degree step angle
This is the most popular step motor. It has a great combination of torque, speed and accuracy.
Due to their high volumes, drives for 2 phase motors are very common and economical.
The basic method of control is to have the motor make one full step as the drive applies full current to
the motor windings. This causes the motor to move in full step increments. When the motor is stepped
at different rates it may make a distinctive sound and can vibrate (resonate) at certain speeds. This is
not a problem for most applications. If it is an issue, motors can be controlled with micro-stepping drives
that smooth motor torque. And many times, resonate speeds can simply be avoided by programming
the drive.
MOONS’ offers 2 phase 0.9 degree step motors, and three phase 1.2 degree step motors, for applications
that need even more accuracy, or motion that is very smooth and quiet.
2 Phase - 0.9 degree step angle
Because each step moves only ½ the distance of 1.8 degree
motors, these motors have higher accuracy and very smooth
movement. The drive for this motor is exactly the same as the
2 phase, 1.8 degree motors. For the same speed, these motors
must have a step rate that is 2 times that of a 1.8 degree motor.
This higher step rate leads to less torque at high speeds.
However, for many applications high speed is not needed, or
higher voltage drives can be used to increase torque at high
speeds.
An example of a good application for 0.9 degree motors are security cameras. These motors allow the
camera to be precisely moved without “camera shake” which causes the picture to vibrate. MOONS’
offers small encapsulated sizes that reduce camera package size, and helps withstand the outdoor
environment.
3 Phase - 1.2 degree step angle
The use of three phases inherently helps to reduce torque ripple and smooth motor performance. 3
phase motors require a 3 phase drive that is different than the drive for 2 phase motors. As compared
to the 1.8 degree two phase motors, the low speed torque is somewhat less. But design improvements
introduced by MOONS’, minimizes this difference. High speed torque can also be comparable. In
addition, MOONS’ size 24 three phase motors are available with PowerPlus technology, for maximon
torque.
3 phase motors are used where maximum performance, and very quiet, smooth precise movement
is need. An example of a good application for three phase motors is in performance lighting. These
spotlights lights need quick movement, and quiet operation so as not disturb the performance.

Step Motor Basics – Applicatons
Applications
MOONS’ stepping motors are widely used to create the motion needed in many types of equipment.
Examples include:
• office automation: printers, scanners, copy machines
• stage lighting: pointing, focus, color changes, spot size, special effects
• banking: check processing, credit card manufacturing, money
scanners & counters
• medical: body scanning, blood analyzers, chemical analysis
• industrial: textile, packaging, robotics, conveyers, assembly, labeling
• telecommunication: phase shift, Tuning, mobile antenna positioning
• security: camera movement
• automotive: fuel metering, steering control
What Is A Stepping Motor
Stepping Motors provide precise position and speed control, without the need for feedback devices
to sense position. The operation of step motors is controlled through electrical pulses that the drive
converts to current flowing through the windings of the motor. As the current is switched the motor
rotates in precise steps of a fixed angle. The motor and drive constitutes a low cost control system that
is precise and simple to construct.
Performance Features of MOONS' Stepping Motors
Accurate Position Control
The number of control pulses defines the motor shaft position. Position error is very small
(less than 1/10th of a degree), and non cumulative.
Precise Motor Speed
Step motor running speed, is exactly determined by the frequency of the control pulses.
Because the speed is very precise and easy to control, step motors are often used where
coordinated motion control is needed.
Forward & Reverse, Pause and Holding Function
Motor torque and position control is effective throughout the entire speed range, including
zero speed holding torque. The zero speed holding torque locks the shaft at the desired
position to hold the load in place.
Low Speed Operation
Step motors produce a large amount of torque, and are easy to control, at low speeds. This
often eliminates the need for speed reduction gearboxes, reduces costs and saves space.
Long Life
The brushless design of step motors leads to motors with a very long life. Step motor life is
usually determined by the life of the bearings.

Step Motor Basics – Structure & Operation
Basic Structure
Operating Principles
In response to each individual control pulse and direction signal,
the drive applies power to the motor windings to cause the rotor
to take a step forward, a step in reverse, or hold in position. For
example, in a 1.8 degree two phase step motor: When both phases
are energized with DC current, the motor will stop rotating and
hold in position. The maximum torque the motor can hold in place
with rated DC current, is the rated holding torque. If the current in
one phase is reversed, the motor will move 1 step (1.8 degrees)
in a known direction. If the current in the other phase had been
reversed, the motor would move 1 step (1.8 degrees) in the other
direction. As current is reversed in each phase in sequence, the
motor continues to step in the desired direction. These steps are
very accurate. For a 1.8 degree step motor, there are exactly 200
steps in one revolution. Two phase stepping motors are furnished
with two types of windings: bipolar or unipolar. In a bipolar motor
there is one winding on each phase. The motor moves in steps
as the current in each winding is reversed. This requires a drive
with eight electronic switches. In a unipolar motor there are two
windings on each phase. The two windings on each phase are
connected in opposite directions. Phase current is reversed by
turning on alternate windings on the same phase. This requires a
drive with only four electronic switches. Bipolar operation typically
provides 40% more holding torque than unipolar, because 100% of
the winding is energized in the bipolar arrangement.

Speed-Torque Characteristics
The dynamic torque curve is an important aspect of stepping motor’s output performance. The
followings are some keyword explanations.
A. Working frequency point express the stepping
motors rotational speed versus the drive pulse
rate.
n = q * Hz / (360 * D)
n: rev/sec
Hz: the frequency value or the driver pulse rate.
D: the subdividing value of motor driver
q: the step angle of stepping motor
E.g.: 1.8° stepping motor, in the condition of I/2
subdividing (each step 0.9°) runs at 500Hz its
speed is 1.25r/s.
B. Start/Stop region: the region in which a stepping motor can be directly started or stopped.
C. Slew Range: the motor cannot be started directly in this area. It must be started in the start/stop
region first and then accelerated to this area. In this area, the motor can not be directly stopped, either.
Otherwise this will lead to losing-step. The motor must be decelerated back to the start/stop region
before it can be stopped.
D. Maximum starting frequency point at this point, the stepping motor can reach its maximum starting
speed under unloaded condition.
E. Maximum running frequency point at this point the stepping motor can reach its maximum running
speed under an unloaded condition.
F. Pull-in Torque: the maximum dynamic torque value that a stepping motor can load directly at the
particular operating frequency point.
G. Pull-out Torque: the maximum dynamic torque value that a stepping motor can load at the particular
operating frequency point when the motor has been started. Because of the inertia of rotation the Pull-
Out Torque is always larger than the Pull-In Torque.

Load Calculations & Tips for Using Step Motors
Calculate the Acceleration Torque
The torque meeded to accelerate the system inertia is often
larger than the friction torque of the load. This limits how quickly
the load can be accelerated.
As shown by the following graph: the dynamic torque
performance of a stepping motor is constant at low speeds.
But at higher speeds, the torque drops as speed increases
(influenced by the motor inductance and drive voltage).
A. Accelerated Motion of Straight Line
Motor’s load value is known as TL, it has to be
accelerated from F0 to F1 in the shortest time
(tr), what is the value of tr?
(1). Generally TJ = 70%Tm
(2). tr = 1.8 * 10 -5 * J * q * (F1-F0)/(TJ-TL)
(3). F (t) = (F1-F0) * t/tr + F0, 0<t<tr
B. Exponential Acceleration
(1). Generally
TJ0 = 70%Tm0,
TJ1 = 70%Tm1,
TL = 60%Tm1
(2). tr = F4 * In [(TJ0-TL)/(TJ1-TL)]
(3). F (t) = F2 * [1 – e^(-t/F4)] + F0, 0<t<tr
F2 = (TL-TJ0) * (F1-F0)/(FJ1-TJ0)
F4 = 1.8 * 10-5 * J * q * F2/(TJ0-TL)
Note: J is the rotational inertia of motor rotor plus the load, q is the angle of each step, it equals the
step angle of stepping motor when motor runs in full step.
Reduction of Vibration and Noise
In a non-loading condition, stepping motors may appear to have vibration or even lose steps when the
motor is running at or close to resonant frequency. Solutions for these conditions include:
A. Have the motor operate outside of this speed range.
B. Micro-step is used for increasing a motor’s step resolution. By adopting the micro-step driving
method, you can divide one step into multiple steps thereby reducing the vibration. This is
accomplished by controlling the motor’s phase current ratio. Micro-step does not increase step
accuracy. However it will allow a motor to run more smoothly and with less noise. When the motor
runs in half step mode the motor torque will be 15% less than running in full step mode. If the motor
is controlled by sine wave current the motor torque will be reduced by 30% if using the same peak
current.
C. Use 0.9° 2 phase step motor, or a three phase step motor.

Bearing Life & Shaft Loading
Moons’ uses high quality bearings optimized for step motors for long life from every motor. To meet
the most demanding applicatons. Most motors can also be provided with larger bearings shafts and
custom construction.
These bearing life curves represent the maximum axial and radial loads
for 20,000 hours L10 bearing life at various speeds. The shaft radial load
limit (and bearing load ratings) are highly dependent on the the distance
from the mounting face where the load is appliced. These curves were
calculated with the radial load applied at the distance from the mounting
face shown on the curve (usually the center of the flat / keyway).
A common cause for shaft (and bearing) failure, are high radial loads
that are created when a pulley is attached to the motor shaft at a large
distance from the motor mounting face, and the belt has high tension. To
avoid this condition mount pulleys and gears as close to the face of the
motor as possible, and avoid over tightening belts. This will dramatically
reduce the shaft stress, and increases the life of the bearings.
