ABSTRACT:
A permanent magnet synchronous motor driving system includes: 1) a permanent magnet synchronous motor, and 2) an inverter. The permanent magnet synchronous motor includes three phase terminals. A resonant frequency is generated between an inductance and a ground electrostatic capacitance which are measured between the following: a) one of the three phase terminals of the permanent magnet synchronous motor, and b) a ground. The inverter drives the permanent magnet synchronous motor. The inverter generates a carrier frequency. The resonant frequency of the permanent magnet synchronous motor is free from a conformance with the carrier frequency of the inverter and is free from a proximity of the carrier frequency of the inverter.
