Description
NEMA23 57HS76-2804 | 57HD3403-21B Stepper Motor – Round Type Shaft
NEMA 23 is a standard for stepper motors that defines the size and mounting pattern of the motor. The "57x57" specification refers to the physical size of the motor, where the motor faceplate is 57mm x 57mm. Here's an overview of NEMA 23 57x57 stepper motors:
Key Features:
- Frame Size: 57mm x 57mm (2.24 inches by 2.24 inches).
- Step Angle: Typically 1.8 degrees per step (200 steps per revolution), though 0.9-degree versions (400 steps per revolution) are available.
- 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.
- Current Rating: The current per phase can range from 1.5 A to 3.0 A or higher, depending on the model.
- Voltage Rating: Operates with driver voltages from 12V to 48V, depending on the motor and driver setup.
- 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.
