A drive aggregate may include an electric motor, a motor control for activating the electric motor, a housing, and a circuit board holder. The electric motor may include a rotor rotatable around an axis of rotation. The motor control may include a circuit board with a power electronics. The housing may include a base body receiving the electric motor and a cover receiving the motor control. The circuit board holder may support the circuit board and may be arranged axially between the base body and the cover. The base body and the cover may be composed of a metal. The circuit board holder may be composed of a plastic.

Drive aggregate

A vehicle may include an internal combustion engine having a crankcase and a supercharging apparatus, and a crankcase ventilation apparatus having at least one oil-separating apparatus including at least one oil separator. An oil return line may communicate separated oil from the crankcase ventilation apparatus to the crankcase. An ejector pump may be driven via a compressed air flow of the supercharging apparatus and may be configured to generate an underpressure for driving a blow-by gas. The crankcase ventilation apparatus may include a pump control valve configured to at least one of regulate and control the compressed air flow through the ejector pump.

Crankcase ventilation apparatus

A vehicle may include an internal combustion engine having a crankcase and a crankcase ventilation device. The crankcase ventilation device may have at least one oil separating device and an oil return that feeds separated oil back to the crankcase. The vehicle may include a conveying device for driving a fluid other than blow-by gas. The conveying device may also drive the blow-by gas in the crankcase ventilation device.
