    The invention relates to electrical engineering, in particular, to the design of a stator of a microelectric motor.
    The aim of the invention is to simplify the manufacture of a motor stator, in particular a stepper with a claw-shaped poles.
    The drawing shows the main elements of an actuator with a claw of different poles with two stator systems, which are located in a common cylindrical housing, in axonometric view.
    When mounted in a cylindrical case 1, a stator system 2, 3, 2 is inserted from the left end, and the right end second stator system 2, 4, 2 is inserted, a permanently magnetized measles 5 is installed, and then j opnyc 1 A cover No. 1 6 and 7 is closed on both sides, and the shaft of the electric motor core 5 is mounted in bearings 8 and 9 in kryshka 6 and 7. Each stator system 2, 3, 2 and 2, 4, 2 has two polar faces. 2 with mutually bent away from each other teeth. In the mounted state, the pole plates of the mounting system are installed with a small tangential distance relative to each other so that their poles on the circle are alternated. The poles of the thus interposed plates on the outside are covered by the excitation coils 3 and 4, which are mounted on the annular coil frame 10 and 11.
    For proper axial and tangential mutual positioning of all four pole plates and both stator systems with respect to each other in a common housing
    1dl of each plate has three special axial slots open from the front sides, and on the pole plates of the plate there are three projections 16 distributed along the circumference, corresponding to the slots
    The pole plates 2, including c)) The radial extrusions 16, are made similarly, and several radial projections 16 J are asymmetrically distributed around the circumference on each pole plate 2. Mutual positioning of four
    2 is achieved due to the length of the slits, and the mutual tangential equilibrium of the four pole plates 2 is carried out only by a special arrangement and configuration of the apertures on the circumference of the common core
    1. Thus, the openings of the slots 12-15, which are open around the circumference, simultaneously serve to prevent axial tilting of the structure and for tangential positioning, providing the necessary rotation of the pole plates and the two stator systems relative to each other. At the same time, the pole plates are stamped with
    5, by the IMM in such a way that the rest of their outer contour is centered radially along the inner circumference of the housing.
    On the common housing from the left
    The first (on the drawing) end face has a deep: Kie slot 12 and from the right end there are deep slots 15. With the axial design, all three slots 12, distributed around the circumference, enter to the axially adjacent -. nor the correspondence, citing with them the three protrusions 116 of the right pole plate 2 of the left stator system 2, 3, 2. Axial slots 15 corresponding
    0 are used for tangential entry and positioning of the left pole plate 2 of the right stator system 2, 4, 2. For axial assembly in short axial slots 14 on
    5 the right end of the common body 1 includes radial protrusions 16 of the right pole plate 2 of the stator system 2, 4, 2. The preferred way is short
    0 axial slots 13 and 14 are used to insert the corresponding protrusions 17 and 18 on the covers 6 and 7. Curved ears 19, radially protruding on the left bearing bracket
    5 b, in the places of the bend, they are inserted into the axial slots 20, located on the side of the left end of the common body 1, which correspond to the bends.
    Due to the presence of a common body, formed from a collapsible flexible stamped part, in which sheet before rolling out the
    55 axial cuts of a certain depth and a certain type, distributed around the circumference and the corresponding radial protrusions, in all the pole sheets, simplifies the engine technology of the invention I. The electric motor controller, in particular, a stepper motor with claw poles, contains the following: one after another along the axis two stator systems with pole plates having radial protrusions and a closed cylindrical case, made of magnetic material, on the side of the ends of which are made Sial slots are distinguished by the fact that, in order to simplify manufacturing, both stator systems are located in one common case, the axial slots on the case have a tangential arrangement and depth that is different for each pole plate, ensuring mutual tan and genial axial positioning, and the radial protrusions on the plates are distributed around the circumference asymmetrically, respectively, differently for each plate, 2. The stator according to claim I, characterized in that the radial protrusions on each pole plate are ying identical. 3, Stator yop, 1 is different from the fact that on each strip plate at least one radial protrusion and the corresponding slot on the body are already wider than fib compared to the other slots. I 4. The stator is about PP, 1-3, about tl and is due to the fact that along the ends of the case there are support plates with radial protrusions mounted in the slots of the case and fixed on by whom.
