| titleOfInvention | A kind of control method of double winding motor |
| abstract | The invention relates to a control method for a double-winding motor, comprising the following steps: Step 1, two sets of controllers are used, each of which operates in a speed control mode, calculates output torques respectively, and adds a torque balance algorithm to one controller; Step 2, the controller without the torque balance algorithm directly controls the winding operation with the output torque in step 1; the controller with the torque balance algorithm collects the three-phase currents of the two sets of windings at the same time, and calculates the current difference value, and perform the torque balance algorithm operation on the current difference, speed command data and motor speed signal, dynamically adjust the output torque of the controller, and control the winding operation, and finally make the output torque of the two sets of controllers equal; The invention makes the two sets of controllers and motor windings have the same load, and the system has a long service life; it can also avoid the low-efficiency operating condition in which one winding is powered by the other winding to generate electricity. |
