About hybrid stepper motor
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.
The above products are only representative models, we can customize the products according to customer requirements. Includes the length and diameter of the shaft.Our company can also provide OEM services.
