Problems solved by technology

[0003] The windings of the existing switched reluctance motors are interconnected, such as figure 1 In the switched reluctance motor shown, the same-phase windings are connected in series, and the copper wire needs to be pulled from the A winding to the opposite A1 winding. The wiring span is large. In the case of limited space in the motor stator, the winding is complicated and the process requirements are high.
Moreover, the windings are connected in series with each other, resulting in increased line loss, wasting the electric energy output by the power control unit, increasing the heat of the motor, and affecting the operation of the motor

Abstract

The invention discloses a novel switched reluctance motor, which is characterized in that each salient pole of a motor stator is provided with an independent winding, the windings on any two salient poles are mutually independent, and each winding is connected to a driving power supply through a power control unit (4); and any salient pole can independent act on a motor rotor, and the in-phase salient poles are mutually matched to drive the motor rotor to rotate. The switched reluctance motor is simple in wiring, low in wiring process requirement and capable of reducing the line loss.

Description

technical field [0001] The invention relates to the field of motors, in particular to a novel switched reluctance motor. Background technique [0002] The structure of the existing switched reluctance motor is as follows figure 1 As shown, windings are wound on the salient poles of each phase of the motor stator, and each phase winding of the motor stator is powered by a power control unit. When the motor is working, the power control unit controls each phase winding in the stator to circulate current in turn. Since the magnetic flux has the characteristic of trying to pass along the path with the least reluctance, the rotor rotates under the action of electromagnetic attraction. [0003] The windings of the existing switched reluctance motors are interconnected, such as figure 1 In the switched reluctance motor shown, the same-phase windings are connected in series, and the copper wire must be pulled from the A winding to the opposite A1 winding. The wiring span is large....
