Abstract:
An encoder assembly (36) is disclosed. The encoder assembly comprises a motor (26) having a rotor (32), and an encoder (36). The encoder (36) comprises an encoder wheel (38) axially coupled to the rotor (32), a first sensor (46a) configured to detect a first velocity at which a portion of the encoder wheel (38) moves relative to the first sensor (46a), and a second sensor (46b) configured to detect a second velocity at which a portion of the encoder wheel (38) moves relative to the second sensor (46b), the first sensor (46a) and the second sensor (46b) positioned approximately 180 degrees apart from each other about an axis of rotation of the rotor (32).
Abstract:
One or more embodiments are directed to an encoder configured to output a signal, and a computing device configured to receive the signal from the encoder and generate a reduced resolution version of the signal, the computing device is configured to transmit the reduced resolution version of the signal to a recipient.
Abstract:
A feedback system (24) for a motor (20) of an elevator system (10) is provided. The feedback system may include a first sensor (26) and a processing circuit (28). The first sensor (26) may be disposed in proximity to a drive component (16, 18, 32) of the elevator system (10) and configured to detect a change in position of the drive component (16, 18, 32). The processing circuit (28) may be configured to receive a first data signal from the first sensor (26) corresponding to the change in position of the drive component (16, 18, 32) and generate a feedback signal for controlling the motor (20) based on the first data signal.
Abstract:
An exemplary device for determining a position of a component moved by operation of a motor includes a rotating member that rotates responsive to operation of the motor. At least one accelerometer is supported on the rotating member. The accelerometer provides at least one of an indication of a tangential force that is tangential to a direction of rotation of the rotating member and a radial force that is perpendicular to the tangential force. A controller determines the position of the component based upon the force indication from the accelerometer.
