Massage motor is mainly used in various massage equipment in a device, its role is to achieve the effect of massage through vibration. The vibration source of the electric massager is the motor. Generally speaking, the motor of the massager is a permanent magnet miniature DC motor. The working principle of the massager is as follows: The rotation of the motor spindle is transmitted to the eccentric wheel through the coupling spring. The function of the eccentric wheel is to convert the rotational motion of the motor into reciprocating motion and pass the reciprocating motion to the vibration head. Because the motor speed is 5000 ~ 10000 RPM, the vibration times of the electric massager are also 5000 ~ 10000 times per minute.
Common faults and repair methods of electric massager
Causes of failure when it does not work (no vibration) : 1. The power plug is not in good contact with the socket; 2. 2. The power switch is not in good contact or damaged; 3. Electrical circuit is broken, unwelded, etc.; 4. The electromagnetic coil of the electromagnetic massager and the motor winding of the motor type rubbing device are open or short circuit.
5. Maintenance method when the mechanical part is stuck:
1. Reinsert the plug; 2. Repair or replace the power switch; 3. Check that the fault point is connected and welded properly. 4. Repair or replace the electromagnetic coil and motor windings; 5. Appropriate adjustment makes the mechanical part run flexibly.
Strong and weak regulation failure when the cause of failure:
1. Weak or weak regulating switch is not in good contact or damaged; 2. The diode in the strength regulation circuit is damaged.
Maintenance method:
1. Repair or replace the strength adjustment switch
2. Replace the diode
Cause of failure when the sound is abnormal during use:
1. The rubber cushion on the iron core of the electromagnetic massager is damaged or falls off, and the running part lacks lubricating oil
2. The running part of the motor massager lacks lubricating oil or the armature of the motor and the stator collide with each other
3. Fasteners in the massager are loose
Repair method: 1. Reinstall or replace the new rubber cushion, appropriately add embellishment lubricating oil; 2. Add lubricating oil or reinstall and adjust properly to remove collisions; 3. Carefully check and tighten the fasteners.
