FIELD WEAKENING CONTROL OF MAGNET MOTOR DRIVES |
摘要 |
A method for field weakening control of a three phase permanent magnet AC motor in a Variable Frequency drive. The VFD drive calculates the three phase voltages to be supplied to the AC motor via a three phase inverter using feedback and feed-forward calculations of quadrature and direct demand currents. |
