Control circuit for polyphase electric motor

Electronic switching devices (IS1, IS2), inserted in two (L1, L3) of the 3-supply phase connections, each comprise two thyristors (Th1, Th2, Th3, Th4) in inverse parallel, with shunt connections completed through the paired contacts (P1, P2) of a 4-pole contactor (S) operated, like the thyristor firings, by a controller (C). The latter includes a voltage generator (1), whose output is fed to the contactor control unit (2) and to synchronous (3) and asynchronous (4) pulse generators providing thyristor firing via an ignition unit (5). During starting, the controlling voltage (1) exhibits a falling characteristic. Firing pulses (3) are applied in synchronism with the supply wave-form, causing the effective motor terminal voltage to rise steadily from zero. At a preset control voltage threshold, asynchronous pulses replace the synchronous; when a second threshold is reached the controller closes the shunt contactor. Asynchronous pulses continue to be applied during the period, which then begins, of normal running. At shut-down, the contactor is opened and the reverse pulse sequence is applied during deceleration.
