Abstract: a multi-phase, multi-pole permanent magnet motor/generator (electric machine) is described, and includes a rotor disposed on a rotor shaft within an annular stator, which may be arranged in a housing with an interposed insulator system. the insulator system is arranged to mitigate and isolate common mode currents in a shaft bearing system by insulating the stator core from an electrical ground return path of an electrical driving source. the electric machine includes a rotor rotatably disposed within a stator, and the stator is secured to the housing with the insulator system interposed therebetween.

Abstract: some embodiments disclosed herein are directed to power transfer in electric motors having segmented windings. in some embodiments, a control system may determine a d-axis command voltage for a secondary winding of an electric motor and a q-axis command voltage for the secondary winding based on a primary winding voltage, primary winding current, secondary winding current, and rotor electrical position. the control system may generate gate control signals based on the determined d-axis command voltage and q-axis command voltage for the secondary winding, and transmit the gate control signals to an inverter coupled to the secondary winding to control an electrical power transfer between the primary winding and the secondary winding. other embodiments may be disclosed or claimed.

Abstract: aspects of the disclosure include using piezoelectric devices to break laminated glass assemblies on demand (e.g., a windshield of a vehicle). an exemplary vehicle includes a laminated glass panel having an outer glass layer, an inner glass layer, and a bonding layer between the outer glass layer and the inner glass layer. the vehicle further includes a piezoelectric device including an actuator and a displaceable element coupled to the actuator. the actuator is made of a piezoelectric material that, responsive to receiving an activation voltage, induces a mechanical displacement in the displaceable element against at least one of the outer glass layer and the inner glass layer. the vehicle includes a controller electrically coupled to the actuator. the controller is configured to deliver the activation voltage to the actuator.

Abstract: laminated vehicle glass structures included printed piezoelectric actuators for sound generation. ring-shaped piezoelectric actuators are printed on an inner surface of a selected one of the exterior glass panel or interior glass panel. the printed piezoelectric actuators are offset relative to a centerline longitudinally extending between the opposing glass panels. also disclosed are processes for forming the laminated glass structures including at least one printed piezoelectric actuator. the laminated glass structures can be utilized about the vehicle anywhere sound generation is desired, e.g., passenger windows, sunroofs, front windshield, rear windshield, and the like. the printed ring-shaped piezoelectric actuators act as a diaphragm to produce sound upon excitation.
