Изобретение относитс  к электромашиностроению .The invention relates to electrical engineering.

Известны электрические машины закрытого обдуваемого исполнени , с полостью ротора, отделенной от полости статора, содержащие короткозамкнутый ротор, охлаждаемый воздухом , проход щим по аксиальным каналам и трубкам, один конец которых размещен в у«а; анных каналах, а другой -- в отверсти х дисков , установленных внутри корпуса с обеих сторон ротора и служащих в качестве уплотнеии  полости статора. Однако -известные машины недостаточно эффективны из-за высокого аэродинамического сопротивлени  при изменении сечени  на входе из трубок в каналы и на выходе из них.Electric machines of a closed, blown version are known, with a rotor cavity separated from the stator cavity, containing a short-circuited rotor cooled by air passing through axial channels and tubes, one end of which is located at a; These channels are located in the holes of the disks installed inside the housing on both sides of the rotor and serve as a seal for the stator cavity. However, the known machines are not sufficiently effective due to the high aerodynamic drag when the cross section at the inlet of the tubes into the channels and at the exit of them is changed.

Предлагаемый электродвигатель отличаетс  от известных тем, что с целью уменьшени  аэродинамического сопротивлени  и улучшени  охлаждени  ротора, трубки свободными концами размещены в отверсти х «ороткоза. мьжающЕх колец. Это улучшает охлаждение ротора.The proposed electric motor differs from the known ones in order to reduce the aerodynamic drag and improve the cooling of the rotor, the tubes with free ends are placed in the holes of the orchosis. loose rings. This improves the cooling of the rotor.

На чертеже показан предлагаемый электродвигатель , продольный разрез.The drawing shows the proposed electric motor, a longitudinal section.

В электродвигателе полость статора 1 отделена от полости короткозамкнутого ротора 2 с помощью щитков 3 и дисков 4. Охлаждение ротора осуществл етс  по аксиальным канала-м 5, в которые воздух попадает по трубкам 6, один конец которых размещен в отверсти х дисков, а другой - в отверсти х короткозамыкающих колец 7.In the electric motor, the cavity of the stator 1 is separated from the cavity of the short-circuited rotor 2 by means of plates 3 and discs 4. The rotor is cooled along the axial channel 5, into which air enters through tubes 6, one end of which is placed in the holes of the discs and the other into the holes of the short-circuiting rings 7.
