FIELD: electricity. ^ SUBSTANCE: control (17A) unit is configured to open shutting down contactor (16) of electric motor not at the moment when detected current condition is determined as abnormal but at the moment when moment when current condition is determined as normal even when basic "MKCO" command becomes switching-off command (L level). ^ EFFECT: creation of driving controller for alternating current motor which can prevent excessive voltage generation between electric motor lines and between electric motor shutting down contactor contacts, and continuous electric arc creation between shutting down contactor contacts. ^ 13 cl, 9 dwg |
