Abstract

PURPOSE:To enable to continue operation when a trouble occurred in the control system for maintenance of constant commutation margin time for the titled motor by a method wherein, when the trouble is detected, the power inverting section is switched to a gate control by a position detecting signal, and the stoppage of the power inverting section can be prevented. CONSTITUTION:The motor 4 is operated using a power rectifying section 1 and a power inverter 3, a position detecting signal is given to a distributor 5, and then the above is inputted to a comparison circuit 12 through an F/V inverting circuit 6 and a delta-wave generating circuit 7. On the other hand, the commutation marginal time of the thyristor group at the power inverter 3 is detected by a circuit 8, compared with the output of the gamma setting pulse generating circuit 9 and inputted to a comparison circuit 12, and controls the power inverting section 3 through a logic circuit 13. Also, a switching circuit 14 is provided, the power inverting section 3 is switched to the gate signal by the signal sent from a trouble detecting circuit 15 when a trouble occurs. Accordingly, the stoppage of the power inverting section 3 and the expansion of the trouble can be prevented, and the operation of the motor can also be continued, thereby enabling to increase the reliability of the motor.
