A stepper motor with a diameter of 42 millimeters, also known as a "42-size stepper motor," is an electrical drive unit that operates in discrete steps.
Technical Specifications:
- Diameter: 42 mm
- Step Angle: Typically 1.8 degrees per step, meaning the motor executes 200 steps per revolution. There are also motors with different step angles for specific requirements.
- Torque: Varies depending on the model and winding type, usually ranging from a few Ncm to several dozen Ncm.
- Winding Type: Bipolar or Unipolar, depending on application requirements.
- Rated Voltage: Typically between 12V and 48V, depending on the power and torque required.
- Connections: Typically equipped with two to six terminals for connection to a driver or control electronics.
Application:
These motors are commonly used in applications that require precise positioning and controlled movements, such as CNC machines, 3D printers, robotics, and automation systems.
Advantages:
- Precise Positioning: Stepper motors enable precise positioning of drive components through incremental movement.
- High Torque Density: Stepper motors typically offer high torque relative to their size.
- Easy Control: Controlling stepper motors is comparatively simple and does not require feedback on the actual position.
