Patent number: 10780849Abstract: Presented are electric drive unit (EDU) assemblies with integrated power electronics, methods for making/operating such EDU assemblies, and motor vehicles equipped with such EDU assemblies. An EDU assembly includes an outer housing that mounts to a vehicle body. The EDU outer housing has internal motor and transmission chambers and an external cavity. A traction motor is mounted inside the motor chamber and drives one or more vehicle wheels to thereby propel the vehicle. A gear train is mounted inside the transmission chamber and drivingly connects the traction motor to the vehicle wheels. An integrated power electronics (IPE) unit, which is operable to control the traction motor, includes an IPE outer housing with a housing chassis mounted inside the external cavity, and a main housing mounted on the housing chassis to define therebetween a power electronics (PE) chamber. Multiple integrated circuit (IC) PE modules are mounted inside the PE chamber.Type: GrantFiled: August 7, 2019Date of Patent: September 22, 2020Assignee: GM Global Technology Operations LLCInventors: Pete R.

Patent number: 9295186Abstract: An electromagnetic interference reduction assembly for a transmission is disclosed. A transmission casing includes a base and walls extending outwardly away from the base to a distal edge. The transmission casing defines a first cavity between the walls and includes a platform disposed between the walls. A power inverter module is disposed in the first cavity and supported by the platform when in the first cavity. The power inverter module generates electrical noise during operation which produces electromagnetic interference. A lid is attached to the distal edge of the walls to contain the power inverter module inside the first cavity. A grounding member engages the power inverter module and the lid when the lid is attached to the transmission casing to electrically connect the power inverter module to the lid to reduce the electrical noise exiting the first cavity which reduces the electromagnetic interference exiting the first cavity.Type: GrantFiled: January 18, 2013Date of Patent: March 22, 2016Assignee: GM Global Technology Operations LLCInventors: William T. Ivan, Jeremy B. Campbell, Konstantinos Triantos
