Permanent magnet motor is a new type of energy-saving and explosion-proof motor. Any machine needs protection after a period of time, and so does permanent magnet motors. The protection requirements for permanent magnet motors are as follows.

1. Timely remove debris, dust, and oil sludge from the outside of the motor base. If there is a lot of dust in the operating environment, it is necessary to clean it every day.

2. Regularly check if the motor terminals and screws are loose or burned.

3. Regularly measure the insulation resistance of the motor, and if the operating environment is relatively humid, it should be measured more frequently.

4. Regularly clean the bearings with kerosene and replace them with new oil (usually every six months). When changing the oil, it is not recommended to fill it up, usually accounting for 1/2-1/3 of the oil chamber. Otherwise, it is easy to heat or throw out. Oil should be added from one side, and impurities that have not been cleaned can be squeezed out from the other side.

5. Regularly inspect the vulnerable parts of the electrical initiating equipment to see if the contacts and terminals are burned, oxidized, and in good contact.

6. Inspection of insulation condition. The insulation ability of insulation materials varies depending on the degree of monotony, so it is very important to maintain the monotony of the motor winding. The insulation of permanent magnet motor wholesale motors can be damaged by factors such as humid working environment and corrosive gases in the working room. A common fault is winding grounding, which refers to insulation damage, causing the live part to collide with metal parts such as the casing that should not be live. This fault not only affects the normal operation of the motor, but also endangers personal safety. So in the use of electric motors, insulation resistance should be checked frequently, and attention should also be paid to checking whether the grounding of the motor casing is firm.

7. In addition to timely protection of the motor according to the above items, there is also a planned overhaul of the motor and related mechanical equipment. Conduct a complete and comprehensive inspection and protection of the motor, supplement the short and worn components of the motor, remove dust and dirt from the surface of the motor, inspect the insulation, clean the bearings, and inspect their wear.
