Description

Изобретение относитс  к трехфазным асинхронным двигател м с дополнительной обмоткой на статоре , возбуждаемой посто нным током с целью компенсации сдвига фаз.The invention relates to three-phase asynchronous motors with an additional winding on the stator, driven by a direct current in order to compensate for the phase shift.

Согласно изобретению, указанную обмотку предлагаетс  соедин ть треугольником, одна из вершин которого разомкнута, а начало и конец фазовых обмоток, сход щихс  в этой вершине, присоедин ть к источнику посто нного токз.According to the invention, said winding is proposed to be connected with a triangle, one of the vertices of which is open, and the beginning and end of the phase windings converging at this vertex, to be connected to the constant current source.

На чертеже изображена схема предлагаемого двигател .The drawing shows the scheme of the proposed engine.

Дл  создани  равномерного пол  посто нного тока по всей окружности статора применена трехфазна  обмотка возбуждени  1, соединенна  в треугольник. При равных напр жени х на фазах в такой обмотке достигаетс  нейтральное состо ние. К началу и концу двух фазовых обмоток в лгобой вершинеTo create a uniform DC field around the entire circumference of the stator, a three-phase field winding 1, connected in a triangle, is used. With equal voltages on the phases in such a winding, a neutral state is reached. To the beginning and the end of the two phase windings in the top of a liar

треугольника подаетс  посто нный ток от любого источиика, напр.шер, от селенового выпр мител  2.a triangle is supplied with a constant current from any source, for example a wire, from a selenium rectifier 2.

Взаимодействие посто нного пол  возбуждени  статора с вращаюпщмс  полем ротора 3 обеспечивает компенсацию реактивного тока двигател .The interaction of the constant field of the stator excitation with the rotor field of the rotor 3 provides compensation for the reactive current of the engine.

При определенных величинах тока возбуждени  и нагрузк) двигагел  возникает даже опережающий ток.At certain values of the excitation current and load, the dvigagel even develops a leading current.

Предмет изобретени Subject invention
