SL stands for Stepper Motor

Ordering Information
When buying POWER JACK MOTION stepper motor,please note the following:

Parameters(New User)

You need to consider the following parameters:

1)   Holding Torque
Large motors require high torque.

2)  Output Speed
If the output speed is high, torque is lower and vice versa.

3)  Pulses Per Second
It refers to no-load starting frequency of stepping motor.

4)  Phase
2 Phase motors are often used for normal applications.
3 Phase motors are used for high speed and high torque requirements.

5)  Special Parameters
In addition, you may need to consider a few special parameters such as water proofing, output shaft length, and diameter among others.

Miscellaneous Information

Make sure to mention your order quantity, expected price, and packing requirements, among others.
