Embodiment 1

[0028] The invention discloses a novel switched reluctance motor. A plurality of salient poles are arranged on the motor stator, wherein each salient pole is individually matched with a winding, and an independent power control unit 4 is connected to each winding, so that each winding is The connected power control unit 4 can individually control the power supply to this winding.

[0029] like figure 2 The three-phase 6 / 4 switched reluctance motor shown has a power control unit 4 individually connected to the winding on each salient pole of the stator, and the three-phase 6 / 4 switched reluctance motor has 6 salient poles, so the stator is connected There are 6 power control units 4, and each power control unit 4 individually supplies power to a winding on a salient pole.

[0030] Compared with the existing switched reluctance motor in the above structure, one power control unit 4 only needs to supply power to one salient pole winding, while in the prior art, one power contro...

[0032] The invention discloses a novel switched reluctance motor. A plurality of salient poles are arranged on the stator of the motor, wherein each salient pole is individually matched with a winding, and each winding is independently connected with a plurality of independent power control units 4, so that each winding is The power control unit 4 connected above can individually control the power supply to this winding.

[0033] like image 3 As shown in the three-phase 6 / 4 switched reluctance motor, the windings on each salient pole of the stator are individually connected with multiple independent power control units 4. In this embodiment, each salient pole winding is connected with 3 independent power control units 4. The power control unit 4 of the three-phase 6 / 4 switched reluctance motor has 6 salient poles, so 18 independent power control units 4 are connected to the stator, and 3 independent power control units are connected to each salient pole winding correspondingl...

Embodiment 3

[0036] The invention discloses a novel switched reluctance motor. A plurality of salient poles are arranged on the stator of the motor, wherein each salient pole is individually matched with a winding, and each winding is independently connected with one or more independent power control units 4, so that each The power control unit 4 connected to each winding can individually control the power supply to the winding; the in-phase salient poles of the motor stator are matched with each other and act on the motor rotor; the windings on the matched in-phase salient poles are independent of each other and not connected; any The power control units 4 connected to the windings on the two salient poles are independent of each other.

[0037] like figure 1 As shown, the in-phase windings of the existing switched magnetic motor are connected to each other, and the in-phase windings are connected to the power control unit 4 in series with each other. However, in the present invention, e...

Abstract

The invention discloses a novel switched reluctance motor, which is characterized in that a plurality of salient poles are arranged on a motor stator, each salient pole is independently matched with awinding, each winding is connected with one or more independent power control units (4), and the power control unit (4) connected to each winding is enabled to independently control the power supplyfor the winding. The novel switched reluctance motor can reduce the manufacturing difficulty and manufacturing cost of the power control units (4) of the existing switched reluctance motor.

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 electricity in turn. Since the magnetic flux has the characteristic of trying to pass along the path of minimum reluctance, the rotor rotates under the action of electromagnetic attraction. [0003] When the existing switched reluctance motor works, the power control unit needs to supply power to the windings on a plurality of salient poles, and the power control unit needs to output a relatively high voltage to drive the motor to work. Due to the above reasons, the existing power co...
