| Abstract |
This paper describes how to measure the magnetic force working in three phase induction motor driven by 20 kHz carrier sinusoidal PWM inverter and its experimental results. Voltage induced in the flux-detecting coil on all stator teeth in the motor is sent to the computer through Analog Digital converter. Moreover frequency and mode of the magnetic force are analyzed by Fast Fourier Transform. Through experimental results, the characteristics of the magnetic force in the motor driven by 20 kHz carrier sinusoidal PWM inverter are evaluated. In addition, the vibration and acoustic noise of the motor driven by 20 kHz carrier sinusoidal PWM inverter are examined and compared with those of the motor driven by a conventional inverter. |
