Abstract (en)
[origin: WO0050329A1] A single inverter (8) provides variable frequency, variable voltage current output (11) to either a hoist motor (3) or a door motor (6), depending on the operating mode of the elevator car (1). A controller (9) provides an input signal (12) to an actuator (10) for switching the output current (11) between the motors (3, 6) by a relay switch (12). The controller (9) includes separate control profiles depending upon which motor (3, 6) is connected to the inverter (8).
