Efficient NEMA 17 hybrid motor with planetary gearbox
This is a NEMA 17 hybrid stepper motor with planetary gearbox 42mm hybrid gear reducer stepper motor.
The 42mm hybrid stepper motor range can be equipped with a high performance gearbox, available in a variety of gear ratios and motor lengths ranging from 25mm to 60mm. Our gearboxes feature a high efficiency, high precision planetary gear configuration. Used in conjunction with a miniature stepper drive to reduce vibration and achieve higher stepping resolution.
Motor length is related to torque, while gearbox length is related to gearbox class and transmission ratio.
In addition, we have a number of different gear ratios for you to choose from, with gear ratios ranging from 3.1 to 200:1.
The higher the gear ratio, the slower the motor speed and the higher the output torque.
Based on the different gear stages, gearboxes will have different lengths and efficiencies. From 90% efficiency in class 1 to 63% efficiency in class 4.

Basic structure of NEMA stepper motors
Application of 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:
Industrial control(CNC, automatic milling machine, textile machinery)
And other automatic systems requiring high precision control.
Notes about hybrid stepper motors
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.
Payment method and payment terms
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)
1.How long is the general delivery time for samples? How long is the delivery time for back-end large orders?
Sample order lead-time is about 15 days,mass quantity order lead -time is 25-30 days.
2.Do you accept custom services?
We accept products customize.including the motor parameter,lead wire type,out shaft etc.
3.Is it possible to add an encoder to this motor?
