Latest Patents

Daryl Marvin holds a patent for an elevator drive control strategy. This invention includes a voltage regulator that selectively introduces current under specific conditions. In one example, the voltage regulator introduces a negative flux current to an electric motor when the motor is operating under conditions corresponding to constant speed movement of an elevator car. The added negative flux current effectively reduces the back-EMF voltage of the motor during the constant velocity portion of an elevator run. This innovative control mechanism maintains control over motor torque, which becomes a function of the added current.
