  • Patent number: 10408184
    Abstract: An electric starter system for a powertrain or other system having an engine includes a solenoid device coupled to a pinion gear, a brushless starter motor, and a controller. The starter motor has actual machine speed, and is connectable to the flywheel via the pinion gear during a change-of-mind event when a commanded engine auto-stop sequence is interrupted before completion. When engine speed exceeds a threshold speed and is less than a calibrated starting speed, the controller executes a method in which closed-loop speed control of the starter motor is enabled using the engine speed as a reference value until an effective machine speed is within a permissible speed delta of engine speed. The controller causes the solenoid device to translate the pinion gear into engagement with the flywheel and starter motor, disables closed-loop speed control, and commands the starter motor to start the engine.

    Abstract: A drive module for a vehicle has a transmission (12) and an electric machine (11) that is coupled to an input shaft (16) of the transmission (12). An air-filled cavity (23) is formed between the electric machine (11) and the transmission (12). The electric machine (11) is an external-rotor motor with a rotor (24) that surrounds the stator (25). A fan impeller (31) rotates with the rotor (24) and draws air out of the air-filled cavity (23) in an axial direction, draws the air through windings (27) of the stator (25) for cooling, and subsequently conveys the air in the radial direction into a housing-side flow duct (34) in which heated air can be accumulated and via which the air can be returned toward the cavity (23). The heated air can be cooled in the region of the flow duct (34) and/or in the region of the cavity (23).
