    Abstract: An elevator drive assembly (30) includes a voltage regulator (40) that selectively introduces current under certain conditions. In one example, the voltage regulator (40) introduces a negative flux current to an electric motor (32) when the motor (32) is operating under conditions corresponding to constant speed movement of an elevator car (22). In one example, the added negative flux current effectively reduces the back-EMF voltage of the motor (32) during the constant velocity portion of an elevator run. A disclosed example includes controlling the added current to maintain control over a motor torque constant, which becomes a function of the added current.
