The Balancing washer is a commonly used mechanical component. It is an intermediate connecting piece in a motor, ensuring the balance between the parts to which it is connected.

For the motor shaft, rotor imbalance may result from the combination of design, materials, manufacturing and assembly. Therefore, a balancing disc is added to ensure that the unbalanced force acting on the shaft at the operating speed remains within the load capacity, and the vibration of the motor shaft is also controlled within the frequency range.
