The reason why the dynamic balance machine can measure the amount of unbalance of the rotor is that the drive plays a vital role. With the development of technology, the current drive technologies that can be used for the dynamic balance machine include the following:

1. Circles drive balance（圈带动平衡）
Adopt belt or silk belt and drive by motor. Generally, the surface of the rotor driven by loop belt must have a smooth cylindrical surface. Its advantages are that the unbalance amount of the rotor is not affected, the operation is simple, and the balance accuracy is high.

2. Gimbal balance（万向节动平衡）
The universal joint is one of the driving methods with relatively high torque. At present, many larger rotors with blades are used. It uses a universal coupling on the linking method of the dynamic balancer, and connects the main shaft with the rotor. The universal coupling drives the rotor. Its main advantages are that it is suitable for irregular rotors, can transmit large torque, and has good wind resistance. The disadvantage is that the measurement accuracy is not high and the rotor installation is more complicated.

3, self-driven balancing（自驱动平衡）
After the rotors are re-arranged, they are corrected and driven by the rotor's own drive. The impact on the balance accuracy is minimal, and the balance accuracy can be higher, but only special rotors allowed by the structure can use this drag mode.
