A Study on Performance and Characteristic Analysis According to the Operating Point of IPMSM Drive

This study presents the characteristics and performance of a motor at operating point based on pulse-width modulation (PWM). PWM is used in modulating output voltage three-phase inverter. The technique has advantages disadvantages depending system size range. For example, some discontinuous (DPWM) techniques are advantageous low-cost systems because they can reduce number switches. Some complicated for software construction require lot computation. In this paper, were constructed by using offset injection method. Therefore, simplified an experimental setup, interior permanent-magnet synchronous (IPMSM) inverter implemented to test control technique. addition, current efficiency analyzed compared speed load motor. According results it possible compare various types rapidly. Additionally, will help select appropriate specific system.
