SYSTEM AND METHOD FOR FAULT PROTECTION OF A MOTOR |
| 摘要 |
An exemplary motor driving system includes a power source, a driving circuit, a controller, a motor, and a protection circuit. The driving circuit including at least one switching device coupled with the power source. The motor includes a plurality of windings. The motor is coupled with the driving circuit and driven by the driving circuit. The controller is configured to provide first switch signals to the at least one switching device of the driving circuit in a normal mode. The protection circuit is coupled with the controller, and configured to generate second switch signals based at least in part on a fault signal in a fault mode and provide the second switch signals to the at least one switching device of the driving circuit so as to reconstruct circuit loops between the driving circuit and the plurality of windings. A method for operating the motor driving system is also described. |

1. A motor driving system, comprising:
a power source; a driving circuit coupled with the power source, the driving circuit comprising at least one switching device; a motor coupled with the driving circuit, the motor comprising a plurality of windings and driven by the driving circuit; a controller configured to provide first switch signals to the at least one switching device of the driving circuit in a normal mode; and a protection circuit coupled with the controller, configured to generate second switch signals based at least in part on a fault signal in a fault mode and provide the second switch signals to the at least one switching device of the driving circuit so as to reconstruct circuit loops between the driving circuit and the plurality of windings. |
