There will be some problems in the use of micro vibration motor, such as frequent tripping phenomenon. In order to prevent the occurrence of such phenomenon, what measures should we take? Please listen to the composition.

    1、 Look

    1. When the motor is seriously overloaded or in phase loss operation, the speed will slow down.
    2. When the motor runs normally but stops suddenly, sparks will appear at the loose part of the wiring; the fuse is blown or some parts are stuck Housing and other phenomena.

    2、 Listen

    When the motor is in normal operation, it should emit even and light "buzz" sound, without noise and special sound.
    If the noise is too large, including electromagnetic noise, bearing noise, ventilation noise, mechanical friction noise, etc., it may be a fault precursor or phenomenon.

    3、 Smell

    By smelling the smell of the motor, the fault can also be judged and prevented. If there is a special smell, the insulation of the motor may be burnt out.

    4、 Touch

    Touch the temperature of some parts of the motor to determine the cause of the fault. To ensure safety, use the back of your hand to touch the electric motor If abnormal temperature is found in the parts around the shell and bearing, it may be: 1. Poor ventilation. Such as fan falling off, ventilation duct blockage, etc. 2. Overload. As a result, the current is too large and the stator winding is overheated. 3. Turn to turn short circuit or unbalanced three-phase current of stator winding. 4. Start or brake frequently. 5. If the temperature around the bearing is too high, it may be caused by bearing damage or lack of oil.
    I hope my answer can help you. If you want to know more knowledge, please pay attention to it. If you have different opinions, please share them and learn together. Thank you http://net-n-dude.com
