Example Embodiment
[0011] Example 1, see figure 1 , the present invention is composed of primary 1 and secondary 4, primary 1 is composed of distributed three-phase armature winding 2 and iron core made of primary laminations 3 using silicon rigid sheets; secondary 4 is composed of silicon rigid sheets It is stacked but has no winding; the primary and secondary poles are salient pole structures, and primary teeth 5 and secondary teeth 6 are respectively set on primary 1 and secondary 4; the number of poles on the primary and secondary poles is the same as the rotary switched reluctance The motor can be made in the form of 4 / 6, 8 / 12 poles, etc. The three-phase armature windings of the present invention are distributed windings, and the mutual inductances of the three-phase windings are coupled with each other, and there are always two-phase excitations at any time during operation.
[0012] This embodiment adopts a unilateral planar linear switched reluctance motor structure, and the linear switc...
Example Embodiment
[0013] Example 2, see figure 2 , the present invention can adopt the bilateral plane linear switched reluctance motor, including the primary three-phase armature winding, primary and secondary poles coupled with mutual inductance, other structures are the same as in Embodiment 1, and the bilateral switched reluctance linear motor with mutual inductance coupling can be The output force of the motor is increased to a greater extent, thereby further improving the power density of the motor, and at the same time eliminating the influence caused by the unilateral magnetic pull.
