Title: Permanent magnet synchronous motor capable of performing stalling and phase loss protection, and protection method therefor
Inventor: JIANG ZE
IPC: H02H7/085
Filed: 2020-09-30
Abstract: Most existing ECM motor control systems use thermal protectors and the traditional observers; using thermal protectors leads to increase of cost; and using the traditional observers may not provide timely protection under the condition where motor parameters are anomalous. Thus, a permanent magnet synchronous motor capable of performing stalling and phase loss protection, and a protection method therefor are provided, which relate the field of motors. A controller (4) of a motor comprises a main control unit (401), a coordinate transformation unit (402), an SVM modulation and inversion unit (403), a current sampling unit (404), a current processing unit (405), a stall and phase loss protection unit (406), and an alarming and shutdown unit (407). Three phases of currents and a rotor speed are sampled in real time by the main control unit (401) and the current sampling unit (404) and are processed by different unit modules, and then are analyzed and calculated by using a fast-speed method and a slow-speed method of the stall and phase loss protection unit (406); when stall and phase loss occur, the alarming and shutdown unit (407) performs shutdown and alarming, so that the stall and phase loss protection of motors can be performed in time, improving the security of motors.
