57BYG hybrid stepper motor/ 8 leads nema 23 stepper motor/ uni polar bipolar stepper motors

General Introduction:

As one of the basic product lines from our products catalogue, 57BYG series of hybrid stepper motors have a long history of more than 30 years. It has become one of our fundamental products, which has won a remarkable reputation throughout both domestic and overseas markets.

The 2-phase hybrid stepper motor rotates 1.8 degree per step. This means 200 steps are needed to complete one revolution. Currently the motor body lengths cover 5 different sized, including 41mm, 51mm, 57mm, 76mm and 100mm. The frame size is internationally called NEMA 23.

The motor varies from to in holding torques. Choices of holding torques will be decided by the design engineers during model selection. What’s more, 8 leads for unipolar or bipolar operation as well as single or double shaft extension or even non-standard customized versions are available for special orders.
