This is 28mm size(NEMA 11) Hybrid stepper motor with D output
shaft.
The step angle is regular 1.8°/step.
We have different height for you to choose, from 32mm to 51mm.
With bigger height, motor with have higher torque, and the price is
also higher.
It depends on customer’s required torque and space, to decide which
height is the most suitable.
In general, the motors we produce the most are bipolar motors(4 wires), we also have unipolar motors available, if customers want to drive this motor with 6 wires(4 phases).

Hybrid stepper motors are in general square shape, and a stepper
motor can be identified by its unique outer shape.
A hybrid stepper motor has 1.8°step angle(200 step/revolution) or
0.9°step angle (400 steps/revolution). Step angle is determined by
tooth number on rotor’s laminations.
There are to ways to name a hybrid stepper motor:
By Metric unit (unit: mm) or by Imperial unit (unit: inch)
For example, a 42mm motor = a 1.7 inch stepper motor.
So a 42mm motor can also be called as NEMA 17 motor.
Explanation of hybrid stepper motor’s name:
For example, 42HS40 stepper motor:
42 means the size is 42mm, so it’s a NEMA17 motor.
HS means Hybrid Stepper motor.
40 means the height is 40mm motor.
We have different height for customers to choose, with bigger
height, a motor will have higher torque, bigger weight, and higher
price.
Here is internal structure of a regular hybrid stepper motor.
Due to high resolution of hybrid stepper motor’s (200 or 400 steps
per revolution), they are widely used for applications requiring
high precision, such as:
3D printing
Industrial control(CNC, automatic milling machine, textile
machinery)
Computer peripherals
Packing machine
And other automatic systems requiring high precision control.
Customers should follow the principle of “selecting stepper motors
first, then select driver based on existing stepper motor”
It is best not to use the full-step driving mode to drive a hybrid
stepping motor, and the vibration is bigger under full-step
driving.
Hybrid stepper motor is more suitable for low-speed occasions. We
suggest the speed does not exceed 1000 rpm (6666PPS at 0.9
degrees), preferably between 1000-3000PPS (0.9 degrees), and it can
be attached with a gearbox to lower it’s speed. The motor has high
working efficiency and low noise at suitable frequency.
Due to historical reasons, only the motor with a nominal 12V
voltage uses 12V. Other rated voltage on design drawing is not
exactly the most suitable driving voltage for the motor. Customers
should choose suitable driving voltage and suitable driver based on
own requirement.
When the motor is used with high speed or large load, it generally
does not start at the working speed directly. We suggest to
gradually increases the frequency and speed. For two reasons:
First, the motor does not lose steps, and second, it can reduce
noise and improve the positioning accuracy.
The motor should not work in the vibration area(below 600 PPS ). If
it must be used at slow speed, vibration problem could be reduced
by changing the voltage, current or adding some damping.
When the motor works below 600PPS (0.9 degrees), it should be
driven by small current, large inductance and low voltage.
For loads with a large moment of inertia, a large size motor should
be selected.
When higher precision is required, it could be solved by adding
gearbox, increasing the motor speed, or using subdivision driving.
Also a 5-phase motor(unipolar motor) could be used, but the price
of the entire system is relatively expensive, so it’s rarely used.
Stepper motor size:
We currently have 20mm(NEMA8), 28mm(NEMA11), 35mm(NEMA14),
42mm(NEMA17), 57mm(NEMA23), 86mm(NEMA34) hybrid stepper motors. We
suggest to determine motor size first, then confirm other
parameter, when you select a hybrid stepper motor.
We provide customization service on motor including lead wire
number(4wires/6wires/8wires), coil resistance, cable length and
color, also we have multiple height for customers to choose.
Regular output shaft is D shaft, if customers require leads screw
shaft, we provide customization service on lead screws, and you can
adjust lead screw type and shaft length.
Picture below is a typical hybrid stepper motor with trapezoidal
lead screw.
If we have samples in stock, we can ship out samples in 3 days.
If we do not have samples in stock, we need to produce them,
production time is about 20 calendar days.
For mass production, lead time depends on order quantity.
For samples, in general we accept Paypal or alibaba.
For mass production, we accept T/T payment.
For samples, we collect full payment before production.
For mass production, we can accept 50% pre-payment before
production, and collect the rest 50% payment before shipment.
After we cooperate order more than 6 times, we could negotiate
other payment terms such as A/S (after sight)
