What to do if the motor does not rotate
The reasons for the motor not rotating are nothing more than circuit breaks, poor contact, and damage to the motor itself. Due to the relatively simple circuit of a general vacuum cleaner, it is not difficult to find where a broken grid or poor contact occurred. Usually, faults are common outside of power switches, fuse tubes, power supply cable trays, or poor coal connections
1. If the fault is found on the power switch, it is mostly caused by poor contact of the switch. During the inspection, special attention should be paid to whether the contact of the winding reel is good or broken, as the installation position of the winding reel is usually hidden, and disassembly is difficult, which is easy to be ignored. 2. If the fuse tube is blown, be sure to identify the cause and eliminate it before replacing it
Use the same specification fuse tube, otherwise it is likely to burn out the fuse again or damage the motor. If the fuse tube is replaced again and still burns out, do not replace it again, let alone try to replace a fuse with a higher rated current, as doing so can easily damage the motor. The correct method is to thoroughly check the cause of the burnt fuse. Practice has shown that if there are no obvious short circuit points in the circuit, the cause is mostly motor overload. It can be emphasized to check. 3. If there are no problems with the circuit and the fuse tube is normal, then the fault is on the motor. Generally, the motor has a broken wire or poor contact fault. Wire breakage usually occurs on the outgoing line of the motor, which can be seen with the naked eye. If it is difficult to determine, a multimeter can be used for testing.
