Electrical performance requirements of motor insulation materials
The reliability and service life of the winding operation depend to a large extent on the performance of the insulating material. The basic requirements for the performance of insulating materials include electrical performance, heat resistance and mechanical properties. In this paper, Liyuan Motor briefly introduces the electrical performance of insulating materials. The electrical properties of insulating materials include breakdown strength, insulation resistivity, permittivity, and dielectric loss.
Breakdown strength of insulating materials
Divide the breakdown voltage by the thickness of the insulating material at the breakdown point, expressed in kilovolts/mm. The breakdown of insulating materials can be roughly divided into three forms: electrical breakdown, thermal breakdown and discharge breakdown.
Electric breakdown. Under the action of a strong electric field, the charged particles inside the insulation move violently, collide and dissociate, destroy the molecular structure, and finally break down, which is called electric breakdown. The electrical breakdown voltage increases linearly with the thickness of the material. In a uniform electric field, unless the time of the impulse voltage is shorter than 10 seconds, the electrical breakdown strength is generally independent of the voltage application time.
Because the rotor electromagnetic induction of the three-phase asynchronous AC motor is induced by the synchronous rotation speed of the stator, it has a slip rate, so the rotation speed of the motor rotor will never reach the rotating magnetic field rotation speed in the stator winding coil. The normal four-pole three-phase motor speed is 1450r/min; if the frequency is 70Hz, according to the calculation formula n=60fp=60×70/2=4200/2=2100r/min; the frequency increases by 20Hz, and the speed increases by 600r/min, An average increase of 10 revolutions per second. Even if it is not overloaded, the time of ordinary motor is a little longer, the motor will heat up and burn the winding coil or damage the bearing due to the increase in speed.
