Vibration motor series to determine the vibration motor synchronous speed. Refers to a pole after pole generator rotor excitation current passed through the armature coil is formed. Simply say that with each turn of the rotor in the stator coil of one turn in the current period can be several different numbers of pole induction formation potential to generate 50hz requires a different speed. 50HZ * 60 sec / min (ie 3000) divided by the number of poles is the number of turns of the motor revolutions per minute. Motor is the same reason, but a reverse process of the generator. Reflects the number of poles of the motor synchronous speed, two-pole synchronous speed is 3000r / min, 4-pole synchronous speed is 1500r / min, 6-pole synchronous speed is 1000r / min, 8-pole synchronous speed is 750r / min. Can be understood: 2 pole is the base (for 3000) JZO vibration motor supply, 4 pole can only addition to the two vibration motor manufacturers, in addition to 6-pole to pole on 3,8 addition to four. Instead of saying two poles should be removed by 3000 2. Number of pole pairs of the vibration motor vibration motors offer more, the lower the motor speed, but it's greater torque and shaker vibration motor is connected plane roughness should be 3.2 or higher, before installing the vibration motor should do the following tests: insulation (1) vibration motor windings, such as the appropriate method should be used to deal with damp insulation resistance 500V megger winding, near the operating temperature (70 ℃), should not be less than 0.38 megohms, otherwise drying should be carried out. (2) vibration motor cable is intact, such as the occurrence of fracture damage should be replaced. (3) vibration motor body is intact, if damaged, please contact us for replacement.
