Description

Linear reversible stepper motors having clearly expressed poles on the stator and located in its slots of the coil of control windings fed from a constant current source through the circuit. the switch providing their alternate switching, and on the core moving in the axial direction (inductor) - clearly expressed poles of symmetric shape, are known. In the known engines of this kind, the control windings are powered from a direct current source through a switch providing their alternate switching, and on the moving core (inductor) there are clearly expressed poles of symmetrical shape.

The proposed electric motor differs from the known ones in that on the stator there are two control windings displaced one relative to the other by one pole division of the stator.

Such an embodiment of the electric motor makes it possible to improve the use of active materials in it.

FIG. 1 and 2 depict the diagrams of the proposed electric motor in two versions.

The electric motor (Fig. 1) has a stator with clearly expressed poles / and e with toroidal coils of two control windings 2 and 3, which are placed in the stator slots. The control windings are displaced one relative to the other by one pole division of the stator and are powered from a DC source through a switch, supporting them with iio alternate switching. In the bore of the stator is located podppzh 1st s axial direction of the core (inductor) 4 with clearly expressed poles 5 of a symmetric shape. In order to excite the inductor poe magnets 6 can be used. The proposed electric motor can also be made in the manner of a reactive machine (Fig. 2). In this case, short-circuited rings 7 are placed in the slots of the core 4.
