Three-phase asynchronous motor test control what's the point?

(1) before installation should check electric between winding and winding insulation resistance to the ground conform to the specified value;(2) test the nameplate voltage,frequency,Ann method is electrical motor 12v 1000w consistent with the circuit,connection is correct;(3) check the motor internal presence of clutter, www.dongfeng-motor.com (4) to see whether there were any oil;(5) check whether the shaft of the motor can rotate freely;(6) test motor grounding is reliable;(7) if full tiejin slip ring,brush surface winder ac motor wind generator is flexible,the pressure is normal,etc.;(8) to test running direction is same as the motor cannot point direction arrow;(9) after operation low speed permanent magnet generator of motor no-load running 2 h,note interest bearing temperature,noise,vibration,the phenomenon such as local heating.
