VT42HS40 42mm size 40mm height hybrid stepper motor NEMA17 with trapezoidal lead screw
This is a regular 42mm hybrid stepper motor (as known as NEMA 17 motor) with a trapezoidal lead screw.
Lead screw is Tr8*4 (P2), which is a 8mm outer diameter, 2mm pitch, 4mm lead, double starts lead screw.
The lead screw parameter is adjustable.
Nut’s thrust and linear speed is related to lead screw’s lead.
Motor’s height is 40mm, the height is related to motor’s torque.
With bigger height, motors have bigger torque.
We provide customization service based on customer’s need.

Product Detail Presentation
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.
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.
