Abstract :
Permanent magnet synchronous motors (PMSMs) operate at a high power factor, efficiency, and reliability. To achieve the performance of DC machines, the PMSM drive is vector controlled. Such a drive is described. The instantaneous position of the rotor is used to determine the required currents which the controller forces into the motor. The actual current is compared to the required or commanded current, and hysteresis or ramp comparison current controllers are used to force the actual current to follow the commanded. Detailed circuits and experimental results are provided. Operation in the flux weakening region is also shown.<>
