The invention discloses a single-phase multi-pole motor for an aircraft. The single-phase multi-pole motor comprises an outer rotor, a spindle, a magnetic pole, a winding, a magnetic pole and a plurality of sensors, wherein the plurality of sensors are distributed on the spindle; the axial mounting position of each sensor is spaced from the central axis of the spindle at a set angle; each sensor correspondingly controls a set current value and a voltage value; a certain sensor is started to work to serve as an original starting point of the motor, and the different running states of the motorare controlled. According to the single-phase multi-pole motor, the technical scheme of effectively controlling and passing a dead point of an electrode is achieved through the technological means, sothat the single-phase multi-pole motor for the aircraft has larger torque and low energy consumption and is suitable for the aircraft to fly for a long time in the multi-condition air.
Description
technical field [0001] The invention relates to a single-phase multi-pole motor, especially a single-phase multi-pole motor for aircraft. Background technique [0002] A multi-axis aircraft is equipped with multiple propellers, which are controlled by multiple motors to achieve flight. The existing multi-axis aircraft generally use three-phase DC motors, which have large energy consumption, small torque, low efficiency, small load, and easy flight. Defects such as short time greatly limit the operating time and limit the scope of use. With the development of technology, multi-axis aircrafts are gradually developing towards large load capacity, such as heavy-duty airships, unmanned aerial vehicles, and small manned aircraft. Contents of the invention [0003] In view of the problems existing in the prior art, the object of the present invention is to provide a new structure, a single-phase multi-pole motor for aircraft with the characteristics of small size, light weight, ...
