57 Stepper Motor (NEMA23 stepper motor) features 57mm flange. It is the most popular medium-size hybrid stepper motor in automation with wide torque range, widely used for transfer, conveyor, engraving and packaging machines. We offer multiple stack length options. Custom dual shaft, keyway, closed-loop encoder, power-off brake, wires and connectors are available.
57mm Standard NEMA23 Flange, Worldwide Universal Mounting Dimension
This 57 Stepper Motor adopts 57×57mm standard flange with industry-standard mounting holes. Replacement of most equivalent motors requires no frame modification. It is the widely used 57 hybrid stepper motor for automation production lines.
Multiple Stack Length Options, Wide Torque Coverage
57 Stepper Motor is available in different stack lengths with holding torque ranging from 1.0Nm to 4.5Nm. Customers can select models according to load requirements for light high-speed and medium-heavy duty applications.
2-Phase 4-Wire Hybrid Structure with Excellent Dynamic Response
57 Stepper Motor uses 2-phase 4-wire hybrid magnetic circuit design with 1.8° step angle. High-resolution microstep drivers can achieve precise positioning. It features fast acceleration and deceleration for various point-to-point motion mechanisms.
Good Heat Dissipation for Long Continuous Operation
57 Stepper Motor features a metal housing with larger heat dissipation area for fast heat transfer and controllable temperature rise during continuous operation. It is suitable for non-stop automation equipment such as packaging and assembly lines.
Rich Accessory Ecosystem for Faster Integrated Solution Deployment
A wide selection of matching drivers, dampers, encoders, brakes and gearboxes are available. No custom accessory development is required, shortening R&D cycle and speeding up integration and commissioning of the whole motion system.
Rich Customization & Complete Set Delivery Available
Our 57 Stepper Motor supports dual shaft, closed-loop encoder, power-off brake and gearbox customization. You can order the motor alone or get packages with stepper motor driver for one-stop purchase and shorten sample validation lead time.

Q: Will 57 Stepper Motor resonate and vibrate during long-time low-speed operation?
A: Resonance may occur at certain low speed range for 57 Stepper Motor. High microstep driver, damper or closed-loop version can effectively suppress vibration and ensure stable operation of the 57 hybrid stepper motor.
Q: Can 57 Stepper Motor be powered by different supply voltages?
A: Yes. Higher voltage improves high-speed performance but brings higher temperature rise. Please select voltage according to motor datasheet and do not exceed maximum voltage rating of motor and driver.
Q: How to select holding torque for power-off brake when 57 Stepper Motor is mounted vertically?
A: At least 1.5 times safety factor is recommended for brake holding torque, which should be larger than torque generated by load weight. Inertia impact during movement should also be considered to prevent load falling after power loss.
Q: What are the common reasons for excessive temperature rise of 57 Stepper Motor?
A: Typical causes: excessive driver current setting, continuous stall, over-high supply voltage and poor heat dissipation. Reduce driver current or add heat sink to solve overheating.
Q: What is the biggest advantage of closed-loop 57 stepper motor compared with open-loop version?
A: Closed-loop version comes with encoder for real-time position monitoring and automatic lost-step compensation. Open-loop type has no position feedback and loses steps easily under overload. Closed-loop model is preferred for applications with fluctuating load.
