Today we are going to carry out vibration motor performance test. This is 220V input. (Force is 30kg) vibration motor. The rated current and power are 0.1A and 30W respectively. We are able to open one side of cover. Now we can see, adjustable eccentric block is connected end of rotor shaft. Both two sides of the nut are same construct. The eccentric block is used to obtain the exciting force. The combination of the specific designed motor and the eccentric block enable the motor to rotate.
