The working principle of the vibration motor is to adjust the eccentric binding block on each end of the motor's rotor, and use its centrifugal rotation to generate excitement, thereby bringing the vibration force of the vibration machine. Due to its own special nature of the vibration source, in addition to causing the lack of phase, overloading, overwhelming, short circuit, etc. of ordinary motor, the main factors that can cause the burning of vibration motors are as follows:
1. Fixed bolt of the ground feet loosen.
The vibration force generated by the vibration motor in the work will make the fixed bolt fixed bolts easily loosen, and the whole machine will be moved, and the ground feet bolt loosen. In addition to causing the ground feet to break, it will also cause other components to tighten the bolt of bolts, so Burning the motor.
2. External cables are worn.
The external cables used by users of vibration motor can only be greater than equal to the square number of cables configured on the vibration motor. Natural hanging. Be careful not to produce vibration friction with objects or tie lines to prevent short circuits of wires in cable rubber damage.
3. The bearing is locked.
The vibration motor bearing must supplement the high temperature oil within the prescribed time, otherwise it will cause the bearing lack of lubrication and cause the motor to burn it.
4. The eccentric block is not adjusted properly.
The adjustment of excitement is the adjustment of the angle of the eccentric throwing clip. The principle is that the greater the angle of the binding block, the greater the excitement, the smaller the angle of the bias, the smaller the excitement. The eccentric dumping of the two ends is a horizontal symmetrical position. When the user needs to adjust the eccentric throwing block, it is necessary to ensure that the eccentric blocks at both ends are adjusted on the same horizontal line. , Cause the motor to burn.
5.No seal.
Because the vibration motor will generate heat adsorption dust during the operation of the vibration motor, and the outdoor or large -dust environment in the mines, metallurgy and other industries, if the first -level sealing protection of the protective cover is missing, and some vibration motor manufacturers have no secondary sealing technology, it is easy to make it easy The inside of the motor enters a large amount of dust, causing the bearing to block, and the wire bag is burned. Therefore, it is required that the vibration motor must be equipped with a protective cover to work.
6. Fever.
The vibration motor allows the circular temperature to increase the temperature of 65 degrees, and it can be cooled naturally, so the surface of the case is required to be kept clean and cannot be covered by the material for a long time and large density.
