Motor Rotor Automatic Balancing Correction

In industrial production, the motor is an essential component. The running speed of the motor is one of the key factors, and its speed directly affects the production efficiency and product quality. However, when the motor is running at a high speed, it will produce unbalance, which will lead to vibration and noise of the mechanical equipment, and may even lead to equipment damage or failure. Therefore, when should the motor rotor to do dynamic balancing has become a very important problem.

Dynamic balancing is a technique used to eliminate unbalance in mechanical equipment. In the motor, the dynamic balancing is usually conducted in the way of rotor weight removal to eliminate the unbalance generated during the operation of the motor. However, what’s the minimum speed requirement for motor rotor to do dynamic unbalance correction

Under normal circumstances, the higher the motor speed, the more likely it will need to be balanced. In general, when the motor speed exceeds 1500rpm, the dynamic balancing is required. This is because at high speed, the vibration and unbalance of the motor will be more obvious, which may cause harm to the equipment and the working environment. For high-speed motors, such as centrifugal fans, grinding machines, and punching machines for industrial purposes, dynamic balancing is even more important

Static balancing is required before the dynamic balancing is conducted. Static balancing refers to eliminating the unbalance by adding or removing weight without rotation. This is a prerequisite to ensure the effect of dynamic balancing. Once the static balancing requirement is achieved, the dynamic balancing can be conducted. Dynamic balancing needs to be carried out by special equipment that measures the vibration level of the motor and eliminates the unbalance by adding or removing the compensating mass.

General speaking, when the motor speed exceeds 1500rpm, it is necessary to carry out rotor dynamic unbalance detection and correction. This helps to ensure that the motor does not produce too much vibration and noise during operation, improving the life and efficiency of the mechanical equipment. Therefore, for motors that require high-speed operation, dynamic balancing is particularly important
