METHOD AND APPARATUS FOR AUTOMATICALLY IDENTIFYING ELECTRICAL PARAMETERS IN A SENSOR-LESS PMSM |
摘要 |
A method and apparatus for determining electrical parameters for commissioning a sensor-less permanent magnet synchronous machine uses knowledge of the rotor position to apply balanced pulses along the rotor magnet axis and perpendicular to the rotor magnet axis allowing measurement of q- and d-inductance at multiple current levels without substantial rotor movement.
