INDUCTION MOTOR PLUGGING AND BRAKING DEVICE Russian patent published in 2000 - IPC

Abstract RU 2152123 C1

FIELD: electrical engineering. SUBSTANCE: device intended for use in high- inertia and high-speed electric drives such as tape drives or those of centrifuges has mechanical drive coil and capacitor connected to neutral wire of motor stator windings and triac with control unit, inserted between phase leads of stator windings. Proposed circuit arrangement affords double-stage mechanical braking and plugging. In addition, mechanical brake eliminates reversal by the end of braking mode of operation. EFFECT: improved effectiveness of braking mode. 1 dwg
