摘要 |
A method for operation of an internal permanent magnet motor having a rotor includes determining whether a neutral point access signal is received from the rotor and operating the internal permanent magnet motor using sensorless signals corresponding to a rotor position and a rotor speed derived by a first sensorless signal estimation method when the neutral point access signal is received, wherein the first sensorless signal estimation method utilizes the neutral point access signal to generate the rotor position and the rotor speed. The method further includes operating the internal permanent magnet motor using sensorless signals corresponding to a rotor position and a rotor speed derived by a second sensorless signal estimation method when the neutral point access signal is not received, wherein the second sensorless signal estimation method does not utilize the neutral point access signal to generate the rotor position and the rotor speed. |
