Description

Дредметом насто щего изобретени   вл етс  устройство дл  пуска в ход и получени  пониженной скорости синхронных и асинхронных двигателей.The dredmetage of the present invention is a device for launching and obtaining a reduced speed of synchronous and asynchronous motors.

На прилагаемом чертеже изображена электрическа  схема предлагаемого устройства.The attached drawing shows the electrical circuit of the proposed device.

Здесь 5i -статор машины А, снабженный пусковой обмоткой и имеющий возможность свободно вращатьс  вокруг ротора , соединенного с нагрузкой.Here, 5i is the position of machine A, equipped with a starting winding and able to freely rotate around the rotor connected to the load.

2 - неподвижный статор мащины В.2 - immobile stator of maschina V.

2 -ротор мащины В, могущий вращатьс  и механически соединенный со статором 5j.2 is a B rotor that is rotatable and mechanically connected to the stator 5j.

К- кольца, подвод щие ток к вращающемус  статору Sj.K-rings, supplying current to the rotating stator Sj.

Агрегат должен быть выполнен так, чтобы число полюсов Р Р.The unit must be designed so that the number of poles is P.R.

Пуск производитс  следующим образом:The start is as follows:

1. Включаетс  рубильник I и тем самым раскручиваютс  статор Si и ротор до об/мин, (при 2Pj 4,).1. The switch I is turned on and thereby the Si stator and the rotor spin up to rpm (at 2Pj 4,).

2. Включаетс  рубильник 2; при этом будет происходить торможение ротора /, и статора S, так как р2 PI (допустим 6). Машина В окажетс  в режиме генератора со скольжением пор дка 33%.2. Turns on switch 2; this will cause braking of the rotor / and stator S, since p2 is PI (say 6). Machine B will be in generator mode with a slip of about 33%.

При затормаживании статора Si с 1500 до 1000 об/мин, ротор тем самым разгон етс  от га 0 до об/мин.When braking the Si stator from 1500 to 1000 rpm, the rotor thereby accelerates from 0 to rpm.

По этому принципу возможно применение многофазных асинхронных машин (например, трехфазных), а также замена в агрегате асинхронной мащины А на синхронную с асинхронным пуском.According to this principle, it is possible to use multi-phase asynchronous machines (for example, three-phase machines), as well as to replace an asynchronous mask A in a machine with a synchronous one with asynchronous start.

Предмет изобретени .The subject matter of the invention.

Устройство дл  пуска в ход и получени  пониженной скорости синхронных и асинхронных двигателей, выполненных с вращающимис  индукторами и  корем и сцепленных ненагруженной частью с тормозной машиной, отличающеес  тем, что в качестве последней применена асинхронна  машина с числом I главного двигател  и доведени  его полюсов, большим ч сла полюсов j рабочей части до скорости, примерглавной машины, служаща  дл  подтормаж вани  ненагруженной частиA device for launching and obtaining a reduced speed of synchronous and asynchronous motors made with rotating inductors and a bark and coupled by an unloaded part with a brake machine, characterized in that the latter uses an asynchronous machine with the number I of the main motor and bringing its poles to weak poles j of the working part up to speed, an example of the main machine used for braking the unloaded part

но пропорциональной разности чисел полюсов обеих машин.but proportional to the difference in the number of poles of both machines.
