DC motor rotors undertake the important task of current transmission and energy conversion. The rotor usually consists of a series of steel or copper rotor cores, windings, and shafts. In DC motors, the rotor length reaches 200mm, which affects the performance of the motor.
Longer rotors may result in higher torque and power density, but may also increase moment of inertia and moment of inertia.
In addition, the design of the rotor also affects the efficiency and smoothness of the motor.
