CAPACITOR-DYNAMIC BRAKING DEVICE FOR INDUCTION MOTOR

摘要

FIELD: electrical engineering; squirrel- cage induction motors. SUBSTANCE: device for braking induction motor without external DC power supply has capacitors connected to motor stator winding, three additional and six auxiliary capacitors, three main and six additional diodes. Cathodes of main diodes are combined and connected through resistor to stator winding neutral point. EFFECT: improved reliability and intensity of braking. 1 dwg øøø1
