Abstract
A bearing encoder is used with two or three Hall effect sensors. One sensor is used to provide a high resolution quadrature signal for speed control, and the other sensor or sensors provide a low resolution signal that may be used as a rescue encoder quadrature signal and/or an ANSI speedcheck encoder signal. The device is suitable for elevator control.
