Abstract: An enclosed digital power amplifier has features for accommodating thermal cycling. The digital power amplifier includes an amplifier board and a controller board, both of which are in a protective housing. The amplifier board includes electronic components mounted on a copper circuit layer that is disposed on a dielectric layer that is disposed on an aluminum substrate layer. The housing includes slotted mounting projections that extend from sidewalls to isolate fasteners from the aluminum substrate layer, and thereby accommodate expansion of the aluminum substrate layer while the digital power amplifier is secured to a surface by the fasteners. Bottom edges of the sidewalls contact a top outer edge of the amplifier board. The mounting projections contact side outer edges of the first circuit board.

Abstract: A motion control system provides optimized communications within and between an amplifier and a profile generation subsystem. In particular, the communications can provide data streams between components of the motion control that are derived from observed variables of the motion system. An amplifier subsystem drives a motor and output motor data indicating status of the motor. The profile generation subsystem issues motor control commands to the amplifier subsystem and generates motor summary data based on the motor data. The profile generation subsystem selectively output an error signal based on at least one of the motor data and motor summary data.

Abstract: A motor control module provides control of a plurality of different motor types, such as a 1-phase DC Brush motor, a 3-phase brushless DC motor, and a 2-phase step motor. The module includes a digital amplifier that is configurable to drive the plurality of different motor types. A motor control unit, coupled to the digital amplifier, controls a motor type driven by the digital amplifier via a command signal to the digital amplifier. The motor control unit also monitors status information about the motor control module, including status information about the digital amplifier. A motor coil interface is coupled to the digital amplifier and configured to connect with the plurality of different motor types.
