The stator pole 2-1 is opposite and parallel to the rotor pole 3-1. The stator pole 2-1 and the rotor pole 3-1 are flat and made of laminated silicon steel sheets. The stator pole 2-1 is provided with winding insulation. Armature winding 2-2 on bobbin.

Working principle of switched reluctance motor: Take a three-phase switched reluctance motor as an example, including A, B, and C three-phase armature windings,

The first set of coil windings of the A-phase armature winding is composed of diametrically opposite and serially connected armature coils A1 and A3, and the second set of coil windings of the A-phase armature winding is composed of diametrically opposite and serially connected armature coils. The armature coil A2 and the armature coil A4 are composed; the armature coil A1 and the armature coil A3 are vertically opposite to the armature coil A2 and the armature coil A4 respectively;

The first set of coil windings of the B-phase armature winding is composed of diametrically opposite and serially connected armature coils B1 and armature coil B3, and the second set of coil windings of the B-phase armature winding is composed of diametrically opposite and serially connected armature coils. Composed of armature coil B2 and armature coil B4; armature coil B1 and armature coil B3 are vertically opposite to armature coil B2 and armature coil B4 respectively;

The first set of coil windings of the C-phase armature winding is composed of radially opposite and serially connected armature coils C1 and C3, and the second set of coil windings of the C-phase armature winding is composed of radially opposite and serially connected armature coils. The armature coil C2 and the armature coil C4 are composed; the armature coil C1 and the armature coil C3 are vertically opposite to the armature coil C2 and the armature coil C4 respectively.

Each armature coil is sleeved on the stator pole 2-1. The working mechanism of the switched reluctance motor is the same as that of the reactive stepper motor, based on the fact that the flux always closes along the path of least reluctance (maximum permeance). When the center lines of the stator and rotor magnetic pole teeth do not coincide, that is, when the magnetic permeability is not at the maximum, the magnetic field will generate a magnetic pulling force to form a reluctance torque, so that the rotor magnetic pole 3-1 turns to the position where the magnetic permeability is maximum. When the current is sequentially applied to each phase winding of the stator pole 2-1, the rotor disk 3 will rotate along a certain direction. If the energization sequence of each phase of the stator pole 2-1 is changed, the motor will change the direction of rotation, but the change of the winding current direction will not affect the rotation of the rotor.

When the rotor magnetic pole 3-1 of the motor is at the position shown in Figure 6, the rotor magnetic pole 3-1 has a slot opposite to a stator tooth of the armature coil A1 and the armature coil A3, according to the working principle of the switched reluctance motor: magnetic flux It always closes along the path with the smallest reluctance (maximum permeance). At this time, when the current is passed to the B-phase armature winding, the magnetic flux generated in the motor will enter the rotor pole from the B-phase stator pole, and the rotor pole 3-1 will generate Reluctance torque, which makes the reluctance in the motor magnetic circuit tend to the minimum state. From the relative positions of the stator pole 2-1 and the rotor pole 3-1 shown in Figure 6, it can be seen that the rotor pole 3-1 will rotate counterclockwise under the action of the reluctance torque, and tend to make the second rotor pole 202 , the centerlines of the fourth rotor pole 204, the sixth rotor pole 206, and the eighth rotor pole 208 coincide with the centerlines of the stator poles covered by the armature coils B1, B2, B3, and B4 respectively. When this process is nearly completed, turn off the B-phase winding current, and energize the A-phase in the same way, then the rotor pole 3-1 will continue to rotate counterclockwise under the action of the reluctance torque, and tend to make The centerlines of the first rotor pole 201 , the third rotor pole 203 , the fifth rotor pole 205 and the seventh rotor pole 207 coincide with the centerlines of the stator poles covered by the armature coils A1 , A2 , A3 and A4 respectively. When this process is nearly completed, turn off the A-phase winding current, and energize the C-phase in the same way, then the rotor pole 3-1 will continue to rotate counterclockwise under the action of the reluctance torque. When the B-A-C phases are energized in turn, and when they are turned on and off in turn, a series of pulsating reluctance torques will be generated on the rotor magnetic pole 3-1, so that the rotor disk 3 will continuously rotate counterclockwise. Conversely, if the C-A-B phases are energized sequentially, the rotor can rotate clockwise. The armature coils A1, A2, A3, and A4 of the A-phase armature winding are connected end to end, and the B-phase armature winding and the C-phase armature winding adopt the same connection method.
