A system and a vehicle are described. An illustrative system includes a vacuum chamber and one or more components of a motor. The one or more components of the motor may be provided in the vacuum chamber and may be configured to move in a partial or complete vacuum created within the vacuum chamber.

A system includes a first power conversion device connected to a first power source, a first isolated power conversion device connected to the first power source, and a second power conversion device connected to the first isolated power conversion device, wherein outputs of the first power conversion device and outputs of the second power conversion device are connected in series, and series-connected outputs of the first power conversion device and the second power conversion device are configured to drive a motor.

An electrified vehicle includes a first electrical component, a second electrical component, and a terminal block assembly adapted to electrically couple the first electric component to the second electrical component. The terminal block assembly includes a housing, a bus bar, and a first seal adapted to seal the second electrical component from a wet environment of the first electrical component.

A motor control device is provided with: an electric motor which drives an applying mechanism for applying torque to the wheels of a vehicle, and has three coils; a drive circuit that supplies current individually to the three coils; and a controller that controls the drive circuit on the basis of the operation amount of an operating member of the vehicle, and adjusts the output of the electric motor. When the vehicle is stopped, the controller executes swing control to periodically increase or decrease the rotary motion of the electric motor, even if the constant state of the operation amount is continued after the operation amount is constant, and the power generated by the applying mechanism and the power received by the applying mechanism are equalized and the rotary motion of the electric motor has stopped.

A non-contact power supply system supplies electricity in a non-contact manner between a power transmission coil of a power supply device 1 and a power reception coil of a vehicle. The vehicle 2 has a wireless communication unit that transmits to the power supply device a startup signal that starts up the power supply device. The power supply device has a reception unit that receives the startup signal. A controller controls the power supply device based on the startup signal. The communication unit transmits a first startup signal when the vehicle is traveling, and transmits a second startup signal when the vehicle is stopped. The controller controls the electricity supply device according to a first control flow when the first startup signal has been received, and controls the power supply device according to a second control flow when the second startup signal has been received.
