When the mud is blocked, the electromagnetic torque is not enough to overcome the resistance torque generated by the mud, the speed ring fails, and the impeller rotates forward and backward at the rotating speed of more than 30rpm to reciprocate, so that the mud flows and the resistance is overcome. The reduction ratio of the speed reducer is 28.5: 1, the motor speed is 536rpm in normal motion. Actually measuring when the motor is dragged at a certain rotating speed, generating corresponding voltage. If the drag rotation speed is 536r/min, the phase no-load output voltage peak value Ep-p is 24.2V, the effective value of the line voltage is 14.8V, and direct current of about 16V (1.1 times) can be obtained through a rectifying circuit.
