NEMA23 57HD3403-21B Stepper Motor 8Kg

Stepper Motor – Round Type Shaft

NEMA 23 is a standard for stepper motors that defines the size and mounting pattern of the motor. The “57×57” specification refers to the physical size of the motor, where the motor faceplate is 57mm x 57mm. Here’s an overview of NEMA 23 57×57 stepper motors:

Key Features:

1. Frame Size: 57mm x 57mm (2.24 inches by 2.24 inches).
2. Step Angle: Typically 1.8 degrees per step (200 steps per revolution), though 0.9-degree versions (400 steps per revolution) are available.
3. Holding Torque: Varies by model, but common torque values range from 0.5 Nm to 2.5 Nm, making these motors suitable for high-torque applications.
4. Current Rating: The current per phase can range from 1.5 A to 3.0 A or higher, depending on the model.
5. Voltage Rating: Operates with driver voltages from 12V to 48V, depending on the motor and driver setup.
6. Applications: Widely used in CNC machines, 3D printers, robotics, and other precision motion control systems.

Considerations:

• Driver Compatibility: Ensure you select a stepper motor driver that matches the current and voltage requirements of the NEMA 23 motor.
• Heat Dissipation: Since stepper motors can get hot during prolonged use, adequate ventilation or heat sinks may be required.
• Microstepping: Using microstepping drivers can enhance resolution and smooth out motion for finer control.
