Abstract
A control device for the door operating mechanism of a lift car is proposed, which contains a three-phase asynchronous motor which is connected to an AC source and whose two windings (1 and 2) are connected to one another in a single-phase reversing circuit, with a phase-shifting capacitor (3). The third winding (10) of the three-phase asynchronous motor is supplied with a direct current, and the ends of the winding (10) are connected to the coil (13) of a control relay for the current, the contact of the control relay for the current being connected in the supply circuit of the two windings (1 and 2) of the three-phase asynchronous motor in the door closing operating mode. The use of such a device enables a high degree of controllability of the rotation frequency of the three-phase asynchronous motor, ensures a very high starting torque, and ensures a low ratio of the starting current to the rated current.
