Abstract:
A feedback system for a motor of an elevator system is provided. The feedback system may include a first sensor and a processing circuit. The first sensor may be disposed in proximity to a drive component of the elevator system and configured to detect a change in position of the drive component. The processing circuit may be configured to receive a first data signal from the first sensor corresponding to the change in position of the drive component and generate a feedback signal for controlling the motor based on the first data signal.
