Publication number: 20210024330Abstract: An elevator door drive comprising: an elevator door motor; and an elevator door controller comprising at least one button; wherein the elevator door controller is arranged to generate a Pulse Width Modulation (PWM) drive signal for driving the elevator door motor; wherein the elevator door controller is arranged to provide an acoustic frequency PWM signal to the elevator door motor responsive to a press of the at least one button. When the elevator door motor is provided with a PWM signal in the acoustic range, the current passing through the motor windings generates forces that result from that current and the magnetic fields in the motor. These forces excite vibrations in the motor components that generate audible noise (which may be referred to as audible magnetic noise or electromagnetic acoustic noise).Type: ApplicationFiled: July 23, 2020Publication date: January 28, 2021Inventors: Herbert Horbrugger, Ruediger Loeb

Patent number: 6161656Abstract: An elevator system includes an electronic driver which transmits a multi-phased electric current through a relay to a motor driving an elevator car. Under normal operating conditions, the motor uses the current from the driver to move the elevator car in a hoistway. When electric power fails, the elevator car is moved by gravity for any necessary rescue or maintenance operations, and consequently moves the motor. The movement of the motor generates a multi-phased electric current therein. The generated current is utilized to power a display panel of a movement indicator, which is automatically connected to the motor by the relay when power fails in the elevator system. The powered display panel informs the operator of the direction and speed of travel of the elevator car.Type: GrantFiled: February 1, 1999Date of Patent: December 19, 2000Assignee: Otis Elevator CompanyInventors: Herbert Horbrugger, Michael Mann, Helmut Schroder-Brumloop
