131 - Stray Capacitance Analysis of a Motor

Motors driven by PWM inverters are widely used in household appliances. It is known that when a PWM inverter is used for drive, common mode current flows and axial voltage is produced in the motor's bearings. Electric corrosion is caused in the bearings by this axial voltage, which can reduce the motor's...
