57BYG hybrid stepper motor/ 8 leads nema 23 stepper motor/ uni
polar bipolar stepper motors
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
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 3.0kg.cm to 12.5kg.cm 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
