Abstract
Изобретение относится к области электромашиностроения, а более конкретно к системам охлаждения электрических машин. Электрическая машина, содержащая ротор с постоянными магнитами и статор, расположенные в корпусе машины и подшипниковых щитов, при этом статор, состоящий из электромагнитных обмоток и сердечников статора из листовой электротехнической стали, закреплен на корпусе машины неподвижно по отношению к вращающемуся ротору, и множество каналов и в сердечниках статора и каналов в роторе для потока текучей среды внутри машины, отличающаяся тем, что ротор выполнен из двух сердечников, расположенных соосно, с встроенными постоянными магнитами, и расположенным между ними распределительным кольцом с отверстиями и кольцевым пазом, а сердечник статора выполнен из двух частей с общими обмотками и встроенной между ними распределительной пластиной с распределительными каналами, при этом каналы распределительного кольца связывают каналы сердечников статора между собой и через каналы распределительной пластины с полостью между обмотками и с полостью между статором и ротором. Технический результат - повышение мощности и момента электрической машины, т.е. обеспечение ее работы, при этом как на малом числе оборотов с большой продолжительностью и частым повторением пусковых нагрузок, так и высоком числе оборотов ротора путем эффективного охлаждения активно нагревающихся элементов электрической машины во всем диапазоне возможного числа оборотов ротора.The invention relates to the field of electrical engineering, and more specifically to cooling systems for electrical machines. An electrical machine containing a permanent magnet rotor and a stator located in the machine body and end shields, while the stator, consisting of electromagnetic windings and stator cores made of sheet electrical steel, is fixed to the machine body motionless with respect to the rotating rotor, and a plurality of channels and in the stator cores and channels in the rotor for the fluid flow inside the machine, characterized in that the rotor is made of two coaxial cores with built-in permanent magnets, and a distribution ring with holes and an annular groove located between them, and the stator core is made of two parts with common windings and a distribution plate built between them with distribution channels, while the channels of the distribution ring connect the channels of the stator cores with each other and through the channels of the distribution plate with the cavity between the windings and with the cavity between the stator and the rotor. The technical result is an increase in the power and torque of an electric machine, i.e. ensuring its operation, both at a low speed with a long duration and frequent repetition of starting loads, and at a high speed of the rotor by effectively cooling actively heating elements of the electric machine in the entire range of the possible speed of the rotor.
