Abstract: Embodiments herein relate to a permanent magnet (PM) motor driven hoist system. The hoist system includes a PM out-runner motor with a stator on a fixed central shaft with stator coils, and an outer rotor assembly coaxial with and rotatable about the stator. The rotor having a rotating housing with an outer surface radially outward of the shaft and an inner surface radially inward of the shaft and plurality of PMs disposed at the inner surface configured to magnetically couple with the stator. The rotating housing coupled to the cable drum such that rotation of the rotor assembly causes rotation of the cable drum. The system also includes a controller connected to a power source and the motor, configured to generate excitation signals applied to the stator coils to induce a torque in the outer rotor assembly and cause it to rotate about the stator and central shaft.

Abstract: An aircraft windshield wiper control system includes an aircraft weather radar system mounted in an aircraft and that detects precipitation in a travel path of an aircraft and an integrated avionics module that receives aircraft weather information from the aircraft weather radar system. The system also includes an aircraft wiper blade motor, a wiper blade motor driver and a wiper control module that receives aircraft weather information from the integrated avionics module and generates a wiper control signal, based on the received information that controls operation of the wiper blade motor drive to cause motion of the aircraft wiper blade motor.

Abstract: Embodiments herein relate to a permanent magnet (PM) motor driven hoist with a motor based electromagnetic brake. The hoist includes a direct current (DC) power source, a PM motor having stator coils and a PM rotor operably coupled to a cable drum with a cable wrapped thereon. The hoist also includes a controller operably connected to the direct current power source and the PM motor, wherein the controller is configured to control the PM motor employing a method to brake the PM motor. The method includes generating control signals in the controller based on a position of the PM motor, applying a braking command signal to the PM motor to magnetically lock the PM rotor of the PM motor for a selected duration, removing the braking command signals for a second selected duration, and repeating the generating, applying, and removing until the PM motor has stopped.

Abstract: A windshield wiper system (WWS) is provided. The WWS includes a wiper blade movable across a maximum sweep angle, a sector gear, a wiper arm coupled at opposite ends thereof to the wiper blade and the sector gear and a bi-directional motor. The bi-directional motor includes a motor shaft and a pinion gear disposed on the motor shaft to engage with the sector gear. The bi-directional motor is operable to drive rotations of the pinion and sector gears in opposite directions via the motor shaft to thereby drive opposite movements of the wiper blade via the wiper arm, respectively, without risking loss of engagement between the pinion and sector gears.
