Motor Fault Detector |
| 摘要 |
A motor control circuit includes a processor configured to calculate a plurality of motor impedances from measurements of an excitation voltage on a power bus to a motor and measurements of a plurality of currents through the motor resulting from the excitation voltage, and the processor configured to calculate individual winding inductances in the motor, based on the measured motor impedances, and configured to determine whether there is an inter-turn winding fault based on the calculated individual winding inductances. |
