Motor rotor is an important component of an electric motor used to generate rotational force. It is typically made of silicon steel sheets, which have high magnetic permeability and low magnetic hysteresis loss, resulting in reduced energy loss and noise, and improved motor efficiency and performance.

In an electric motor, the rotor is driven by a rotating magnetic field, producing torque to rotate the axis. The rotor design typically considers matching the specific power and speed requirements of the motor, while minimizing energy loss and noise as much as possible. The characteristics of Motor Rotor include high magnetic permeability and low magnetic hysteresis loss, allowing it to more effectively utilize electromagnetic energy when rotating, resulting in improved motor efficiency and performance.
