| Abstract |
New sensor elimination method, using the Carrier Frequency Component
Voltage (CFCV), in a Pulse Width Modulation(PWM) inverter supplied Interior type Permanent Magnet (IPM) motors control is proposed. Characteristics of the Carrier Frequency Component Voltage (CFCV) and Carrier Frequency Component Current (CFCC) in the PWM inverter are studied and used as the rotor position in:IOrmation source. Mathematical expression relating the rotor position to the CFCV, CFCC and the motor parameter is derived. Using motor parameters
and measured CFCV and CFCC the rotor position is to be calculated. The simulation result is presented and discussed. Some laboratory results are also included. Simulation result shows that the expression gives exact rotor position. |
