Vibrating motor is to install a set of adjustable eccentric blocks at both ends of the rotor shaft, and the centrifugal force generated by high-speed rotation of the shaft and eccentric block is used to obtain the exciting force. The vibration frequency range of vibrating motor is large, so the mechanical noise can be reduced only with the combination of exciting vibration force and power. The vibrating motor has six classifications according to the classification of starting and running mode and the classification of Operation speed.
Vibration of vibrating body is produced by two groups of excitation system, and its vibration form is called composite vibration. There are two types of dual-frequency composite and double-amplitude composite. Some special performance vibrating sieving equipment, uses two different models different rotational speed vibration motor, the feeding end and the discharging end of the sieving machine are divided into a large amplitude and low frequency vibration, while the output end presents a small amplitude and high frequency vibration, and the middle of the sieving machine overlaps two kinds of vibrations, which makes the sieving machine play a more effective sieving function.
