| AC motors that drive PWM inverters are widely used in household appliances.Motors
used for PWM inverter power supplies are known to produce shaft voltage
which reduces the reliability and life span of the motors.It is advantageous
to investigate the stray capacitance using an analysis in advance because
the shaft voltage is produced by the stray capacitance of the motor.This
example presents the use of an electric field analysis to obtain the stray
capacitance between the IPM motor's coil and stator core, rotor core and
stator core, and inner and outer rings of the bearing. |
