3상 유도전동기의 무부하 및 부하 운전시 전자기 소음의 변화

When a squirrel cage induction motor is loaded, the electromagnetic noise can increase depending on the load current. It is due to the air gap harmonic fluxes from the rotor current induced during loading. This unfavorable noise can be anticipated by calculating the radial force waves in the air gap, vibration mode shapes of them, and stator core natural frequencies of each mode. With the experimental tests with the different rotor slot numbers, the variation of electromagnetic noise is studied between un-loaded and loaded running.

The voltage stress on line-end coil of the stator winding in the induction motor fed by a PWM inverter is analyzed, using the computer model based on multi-conductors transmission line. A method to calculate circuit parameters, especially, capacitance between the turns and ground is proposed. The voltage distributions inside coil at motor terminal depending on dv/dt are investigated through simulation studies.
