Abstract
PURPOSE: To simplify an induction motor controller by applying a three-phase control signal used at accelerating time to DC dynamic braking used between two phases of a primary voltage control three-phase induction motor.
CONSTITUTION: A speed control circuit 1 produces a control signal 51a to a phase control circuit 51 upon reception of an instruction signal 2a from a speed instruction signal generator 2 and a speed signal 4a from a speed detector 4. When an acceleration signal is given, three-phase control gate signal is produced to SCR1∼SCR6. When DC dynamic braking instruction is given then, three-phase control is shut off to apply a gate signal for synchronizing SCR6, 9 with SCR9, 10 to a single phase bridge circuit of SCR1, 6, 9, 10 to thus control the single phase for the DC dynamic braking operation.
