Motor points for attention

(1) before disassembly,should surface dust with compressed magnet generator air

blowing off the motor,and scraped clean surface dirt.2 choose motor working place,the disintegration of the clean up the scene environment.(3) familiar with acmotor2.blogspot.com the

motor structure characteristics and maintenance technical requirements.(4) ready to collapse the

required tools and equipment (including special tools).5] in 220v electric motor

order to further understand the defects of the motor running,conditional when can do an inspection test before disassembly.For this,turn motor with load test,the detailed check parts,such as temperature,sound,vibration motor,and test the voltage,current,speed,etc.,and then disconnect the load,do a no-load check test,no-load loss and no-load current is measured and recorded.

[6] to cut off the power supply,electrical wiring to remove,recorded.Once the appropriate voltage test motor insulation resistance by megger are.Maintenance in order to keep pace with electric motors price .The Times when measured insulation resistance compared to determine the motor insulation change trend and insulating state,should be measured under different temperature insulation resistance value of the conversion to the same temperature,the average conversion to 75 ℃.Being tested to absorb than K.When the absorption ratio greater than 1.33,which indicates that the motor insulation or degree of be affected with damp be affected with damp be affected with damp be affected with damp or not serious.In order to compare with previous data,also want to add any temperature measured absorption than the conversion to the same temperature.
