A motion system includes one or more batteries that output direct current electrical power to first and second inverters that generate first and second alternating current electrical power outputs. A first electric machine is configured to be operated by the first alternating current electrical power output. A second electric machine is configured to be operated by the second alternating current electrical power output.

Motion system

A vehicle includes a control system, a sensing system that senses an environment of the vehicle, and a propulsion system, a braking system, and a steering system that are operated by the control system to navigate the vehicle according to the sensing system and without direct human control. The propulsion system and the braking system are operated by the control system to cooperatively decelerate the vehicle. The braking system includes an inboard friction brake that is associated with one or more wheels of the vehicle and does not form unsprung mass of the vehicle.

Vehicle deceleration systems

An electric motor includes an end turn ring and a cooling structure that is in a thermally conductive relationship with the end turn ring.

Vehicle deceleration system

An electric motor includes a configuration that directs at least a portion of an electric field generated by phase windings into a stator.

Aspects of the present disclosure involve an inverter employing switches of different types in parallel. In one example, an apparatus includes a voltage-source converter that may have a plurality of switch positions collectively coupled to convert an input to an output. At least one switch position may include a first switch of a first switch type and a second switch of a second switch type different from the first switch type. Also, the first and second switches may be coupled in parallel. The converter may also include a switch control circuit to generate, for each of the at least one of the switch positions, a first control signal to operate the first switch of the switch position, and a second control signal to operate the second switch of the switch position.
