NEMA23 57HS112-4204 D-Type Shaft Stepper Motor

This NEMA23 stepper motor provides a substantial holding torque of 31 kg-cm, equivalent to 3.1 N-m. This high torque ensures strong and stable positioning, making it suitable for demanding applications in various digital fabrication and automation systems.

The motor features a standard 1.8° step angle. This angle dictates the rotational increment per pulse. A smaller step angle typically allows for finer resolution and greater positional accuracy, crucial for precise movements in 3D printing or CNC machining.

The D-type shaft is designed with a flat section to prevent slippage when a pulley, gear, or coupler is attached using a set screw. This design provides a more secure mechanical connection compared to a perfectly round shaft, ensuring reliable power transmission and consistent performance.

This stepper motor operates optimally with a current of 4.2 Amperes per phase. It's essential to use a compatible stepper motor driver capable of supplying this current to achieve the motor's specified torque and performance characteristics without overheating or underpowering.

While capable of reliable operation, this NEMA23 stepper motor is primarily optimized for low-speed, high-precision applications. Stepper motors generally exhibit reduced torque at very high speeds, and resonances can occur. For extremely high-speed requirements, alternative motor types may be more suitable.
