good motor selection successfully applied to the equipment, is not the end of the motor used in the daily use of equipment, to ensure that the motor continues to play the highest working efficiency, also need motor for maintenance. This article mainly aims at the maintenance of the brushless dc motor was presented. Brushless dc motor has the ac motor is simple, reliable operation, convenient maintenance, and dc motor running with high efficiency and good speed regulating performance advantages, but also because without being limited by the mechanical commutator, easy to accomplish the large capacity, high speed, in the aerospace, military industry, CNC, metallurgy, medical equipment and other fields has a broad application prospect. In recent years, the club step motor, brushless dc product shipments are growing. In order to make the function of the brushless dc motor to get better, it is important to note that the daily maintenance and maintenance. In everyday use, we can through the following method prolongs the service life of the motor, raise the use efficiency of the motor. Brushless dc motor maintenance methods: 1, familiar with the brushless dc gear motor, structure features and maintenance technical requirements; 2, select the disintegration of the motor working site, clean up the scene environment; 3, in order to further understand the defects in operation of the brushless dc motor, the conditional check test can be done before disassembly time; 4, before disassembly, brushless dc motor with compressed air blowing off the motor surface dust, dirt and surface wipe clean; 5, ready to collapse the required tools,Including special tools)And equipment; 6, to cut off the power supply, electrical wiring to remove, recorded.
