Description

This is a planetary gearbox stepper motor 35mm (NEMA 14) square hybrid stepper motor.

The motor length for this product is generally between 27 and 42mm, special lengths can be customised. The longer the length, the higher the torque of the motor.
Hybrid stepper motors are generally square in shape and stepper motors can be identified by their distinctive external shape.
In addition, there are two options for the stepping angle of the motor: 0.9 degrees and 1.8 degrees.

The type of output shaft, our standard shaft is a D-shaft, this can be customised to suit the user's requirements.

The length of the lead wire and the type of connector can also be used with standard connectors, which can also be customised.

A hybrid stepper motor is available with a 1.8° step angle (200 steps/revolution) or 0.9° step angle (400 steps/revolution). or 0.9° step angle (400 steps/revolution). The stepping angle is determined by the number of teeth on the rotor blades.

It can also be fitted with a gearbox, which has different gear stages for different speed ratios and of course different lengths, the longer the length the lower the efficiency.

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:
3D printing
Industrial control(CNC, automatic milling machine, textile machinery)
Computer peripherals
Packing machine
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.

定制服务：
Customization service:
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.
