The invention discloses a single-phase motor control system comprising a current feedback unit, a voltage feedback unit, a speed feedback unit, and a plurality of sensors distributed on a motor spindle. The plurality of sensors detect positions of motor windings; and one sensor controls one set current value and one set voltage value correspondingly, thereby controlling different operating statesof the motor. When the motor works, the current, the voltage, and the motor running speed are fed back to a processor by the current feedback unit, the voltage feedback unit, and the speed feedback unit; and on the basis of current, voltage and speed control, the safety of the motor and power supply system is guaranteed. According to the invention, the dead point of the electrode is controlled effectively by technical ways; and the motor is controlled by the control system to realize the large torque based on the dead point of the electrode. Moreover, the energy consumption is low; and the application scene of the motor is broadened.
Description
technical field [0001] The invention relates to a single-phase motor control system. Background technique [0002] Electric aircraft and electric vehicles are powered by power supply and driven by electric motors. The prospect of electric drive is widely optimistic, but the current technology is not yet mature. [0003] The power supply provides electric energy for driving the motor, and the motor converts the electric energy of the power supply into mechanical energy, and drives the aircraft and automobile to work through the transmission device or directly. [0004] Due to the limited capacity of batteries loaded on aircraft and automobiles, the efficiency and energy consumption of electric motors are directly related to the cruising range of aircraft and automobiles. Existing aircraft and automobiles generally use three-phase DC motors, which have high energy consumption, small torque, and low efficiency. , short battery life and other defects, which greatly limit the w...
