Abstract: A communication module mounted to a motor provides for communication between a motor controller and a motor or between the motor controller and devices mounted on or proximate to the motor. The communication module may be configured to accept signals from various different encoders and/or load devices mounted on or proximate to the motor. The communication module receives a position feedback signal from a primary encoder interface and is configured to transmit the data to the motor controller at a periodic update rate. The communication module also receives feedback signals from at least one additional device and transmits the data to the motor controller. The communication module synchronizes its periodic update rate with the motor controller such that the position feedback signal may be utilized to control operation of the motor. The additional feedback signals may be communicated at the same or differing update rates.

Abstract: An encoder for detecting angular position of a rotor in a motor includes a modular hub, configured to be connected to the rotor, and sensing electronics mounted within an end bell of the motor. The modular hub provides a universal mounting configuration for connecting different configurations of the encoder to the motor. The modular hub includes a mounting portion and sensor face on which different elements for sensing may be mounted. The elements may include polarizing tape to reflect polarized light, magnets generating a magnetic field, or ferrous teeth configured to interact with a magnetic field. The sensing electronics include sensing devices corresponding to the elements mounted on the sensor face. The sensing devices may be a paired light emitter/receiver, magnetic sensors, or a paired magnetic field generator/sensor. The sensing electronics convert the sensed signals to uniform feedback data for the motor controller regardless of the encoder configuration.

Abstract: A motor includes a brake diagnostics system with sensors to assess the brake assembly condition. Acoustic or other vibration sensors provide vibration data that is compared to known vibration spectrum data to compare the condition of the brake assembly to a properly functioning brake assembly. The brake diagnostics system monitors current flow in the brake coil to assess the condition of the brake assembly. The sensed brake coil current is compared to known coil current spectrum data to compare the condition of the brake assembly to a properly functioning brake assembly. The voltage input to the brake coil is varied depending upon the current sensed in the brake coil to minimize heat in the brake coil. The motor also includes a resilient layer of thermally conductive material located between the brake assembly and the housing that provides a continuous, uninterrupted thermal pathway between the brake assembly and the motor housing.

Abstract: A method and system for communication between a motor controller and an analytic module includes a Single Pair Ethernet interface with power supplied over the two data lines. The analytic module, in turn, connects to a motor or other devices proximate the motor. The analytic module receives input signals from the motor or different types of sensors or devices. A processing unit in the analytic module may perform some initial processing on the incoming data. The processing unit is configured to transmit either the raw input signals or processed data via the Single Pair Ethernet connection back to the motor controller or to other controllers in the system with the motor controller acting solely as a pass-through gateway. The analytic module unit may be configured to transmit data at different update rates. One of the update rates may be synchronized to an update period in the motor controller.

Abstract: A motor includes a housing containing a rotor and stator. A brake assembly is adapted to restrain rotation of the rotor. A brake controller includes a brake diagnostics system. At least one vibration sensor is located in the housing and provides vibration data to the brake diagnostics system in response to a brake operation cycle of the brake assembly. The vibration data is used by the brake diagnostics system to assess an operative condition of the brake assembly.
