NEMA 23 Stepper Motor 57BYGH82
The NEMA 23 Stepper Motor 57BYGH82 is a hybrid bipolar motor with an 82 mm body, 1.8° (200 steps/rev) resolution, and four-wire configuration. Rated for 5 A per phase and with a phase resistance of 0.6 Ω, it offers strong holding torque while enabling high dynamic response. The motor maintains insulation of ≥ 100 MΩ @ 500 VDC and withstands 500 VAC for 1 min. With a temperature rise limit of 80 °C and operation over –20 °C to +50 °C, this motor is designed for continuous industrial use. Shaft is 8 mm D-shape.
Features
- Precise 1.8° step angle for accurate motion control.
- High holding torque suitable for heavy-load applications.
- Durable 82mm body length for enhanced performance.
- Low phase resistance for efficient power consumption.
- Compatible with most bipolar stepper motor drivers.
- 8mm D-type shaft for secure mechanical coupling.
