относитс  к области электроИзобретение техники.relates to the field of electrical engineering.

Известны роторы электрических машин с когтеобразными полюсами, содержащие сердечник , на котором размещен каркас с обмоткой возбуждени . На цилиндрической части каркаса выполнен паз, который при намотке катушки сжимаетс , сокраща  внутренний диаметр каркаса, вследствие чего обеспечиваетс  плотное прилегзНие каркаса к сердечнику .The rotors of electric machines with claw poles are known, comprising a core on which a frame with an excitation winding is placed. A groove is made on the cylindrical part of the frame, which is compressed when winding the coil, reducing the internal diameter of the frame, as a result of which a tight fit of the frame to the core is ensured.

На торцовых поверхност х каркаса выполнены отверсти . При пропитке ротора лак проникает в указанные отверсти  и после застывани  создает механическое сцепление обмотки возбуждени  с каркасом.Holes are made on the end surfaces of the frame. When the rotor is impregnated, the varnish penetrates into these holes and, after solidification, creates a mechanical coupling of the excitation winding to the frame.

Однако при высоких скорост х вращени  в известных роторах обмотка возбуждени  может смещатьс  из-за недостаточного м.еха«ического сцеплени .However, at high rotational speeds in known rotors, the field winding may shift due to insufficient mechanical coupling.

Дл  предотвращени  проворачивани  обмотки возбуждени  относительно каркаса в предлагаемом роторе на внутренней поверхности цилиндрической части каркаса выполнены два продольных выступа, смещенные друг относительно друга на 180°.To prevent the excitation winding from turning relative to the carcass in the proposed rotor, two longitudinal protrusions are made on the inner surface of the cylindrical part of the carcass, shifted relative to each other by 180 °.

На фиг. 1 изображен описываемый ротор вFIG. 1 depicts the described rotor in

сборе; на фиг. 2 - торцова  поверхность каркаса и разрез по А-Л.collecting; in fig. 2 - the end surface of the frame and a section along the AL.

На сердечнике / ротора расположен каркас 2 с обмоткой возбуждени  3. Обмотка возбуждени  имеет выводы 4. Когтеобразные полюса 5 напрессованы на вал 6. На внутренней поверхности каркаса выполнены выступы 7, смещенные друг относительно друга на 180°. Под углом в 90° к выступам 7 выполнены продольные пазы 8, способствующие приобретению внутренней поверхности цилиндрической части каркаса эллипсной формы. Это происходит при сборке сердечника с каркасом. При намотке обмотка возбуждени  также приобретает форму эллипса, что предотвращает ее -смещение относительно каркаса при вращении ротора.On the core / rotor, there is a frame 2 with an excitation winding 3. The excitation winding has terminals 4. The claw-shaped poles 5 are pressed onto the shaft 6. On the inner surface of the frame there are protrusions 7 that are 180 ° offset from each other. At an angle of 90 ° to the protrusions 7, longitudinal grooves 8 are made, facilitating the acquisition of the inner surface of the cylindrical part of the frame of an elliptical shape. This occurs when assembling the core with the frame. When winding, the field winding also takes the form of an ellipse, which prevents its displacement relative to the frame when the rotor rotates.
