Известны устройства дл торможени асинхронного короткозамкнутого двигател , содержащие источник посто нного тока, подключенный к нейтрали обмоток двигател и элементам, образующим искусственную нулевую точку.Devices for braking an asynchronous short-circuited motor are known, which contain a direct current source connected to the neutral of the motor windings and elements forming an artificial zero point.
Дл упрощени получени ползучей скорости двигател при использовании устройства с однообмоточныг двухскоростным двигателем в предлагаемом устройстве в качестве элементов, образующих искусственную нулевую точку, использованы две полуфазы обмоток двигател , включенных по схеме двойной звезды, а источник посто нного тока подключен между нейтралью одной звезды и средней точкой двух других полуфаз.To simplify creeping motor speed when using a device with a single-winding two-speed motor, in the proposed device, two half-phases of the motor windings, connected according to the double star circuit, are used as elements forming an artificial zero point, between the neutral of one star and the midpoint two other semi-phases.
Между одним из выводов источника и нейтралью обмоток двигател дл увеличени симметрии может быть введен резистор.A resistor can be inserted between one of the source pins and the neutral of the motor windings to increase symmetry.
На чертеже дана принципиальна схема описываемого устройства.The drawing is a schematic diagram of the described device.
Устройство содержит источник 1 посто нного тока, подключенный между нейтралью одной звезды и средней точкой двух других полуфаз обмотки 2 асинхронного двигател , и резистор 3 дл поддержани симметрии схемы . Посто нный ток протекает по всем обмоткам асинхронного двигател : от источника 1 посто нного тока через фазы А и СThe device contains a source of direct current 1, connected between the neutral of one star and the midpoint of the two other semi-phases of the winding 2 of the induction motor, and a resistor 3 to maintain the symmetry of the circuit. DC current flows through all windings of an induction motor: from DC source 1 through phases A and C
электродвигател и из сети через фазу В (посто нна составл юща однополупериодного выпр млени ), источник 1, резистор 3 и полуобмотки фаз А и С. Величина посто нной составл ющей выпр мленного напр жени сети может регулироватьс резистором так, чтобы асимметри схемы по посто нному току была минимальной.motor and from the network through phase B (constant half-wave rectifying component), source 1, resistor 3 and phase winding A and C. The value of the constant rectified voltage component of the network can be adjusted by a resistor so that the asymmetry of the circuit is constant current was minimal.
