    摘要： A position sensing system includes a plurality of two-axis anisotropic magneto-resistive (AMR) sensors to determine the position of a user interface. A magnetic member is coupled to the user interface, which is movable to a position along a random path. The plurality of two-axis AMR sensors is arranged in a two-dimensional sensor array that is spaced apart from the magnetic member. A signal processor circuit is operable to sense the electrical resistance values of each two-axis AMR sensor, to determine the position of the user interface from the resistance values, and to supply position feedback data representative of the determined position.

    摘要： An electric motor system includes a motor brake control circuit that uses current induced in the motor stator from generated back EMF to keep the motor brake energized and in its disengaged position, should electric power be lost to the motor system. When the motor has slowed sufficiently that the induced current is no longer sufficient to keep the motor brake energized, the motor brake will move to its engaged position, and prevent further motor rotation. The motor rotational speed at which the motor brake is no longer energized is sufficiently low that any potential degradation or other deleterious effects from motor brake engagement are minimized.

    摘要： A motor control architecture is provided that simultaneously controls multiple motors. The motor control system includes memory, a plurality of motor control processors, and a communication controller. The motor control processors are each responsive to control signals supplied from the communication controller to selectively retrieve system commands and motor positions from the memory, to generate motor commands, and to supply the generated motor commands to the memory. The communication controller selectively receives system commands and transmits the received system commands to the memory, selectively supplies the command signals to selected ones of the motor control processors, selectively receives motor positions from a plurality of motors, selectively transmits motor positions to the memory, selectively retrieves generated motor commands supplied to the memory, and selectively transmits the retrieved motor commands.

    摘要： A no-back device for a power drive unit is configured such that, during operation of the power drive unit, the no-back device does not supply magnetic or frictional force against power drive unit rotation. The no-back device is implemented either redundantly or no-redundantly, and includes a latch rotor and an electromagnet. In both embodiments, the latch rotor is coupled to the power drive unit to rotate therewith, and the electromagnet is coupled to receive a flow of current and, upon receipt thereof, generates a magnetic field force that opposes rotation of the latch rotor. In the redundant embodiment, the no-back device further includes one or more permanent magnets, and the magnetic field generated by the electromagnet selectively opposes or aids the magnetic field supplied by the permanent magnet(s).
