    摘要: A turbocharger having an electric motor for assisting spin up of the rotor employs a shaft carrying the turbine and compressor impeller with a unitary pinned semi-floating bearing supporting the shaft and a spacer collar carrying the electric motor magnet. The unitary bearing has integral thrust faces engaging a hub of the turbine wheel and the spacer collar. A reduced diameter of the shaft received in the spacer collar allows the collar to engage a greater diameter bearing land allowing the attachment of the compressor impeller with a nut on the shaft extending through a bore in the impeller to firmly engage the impeller, spacer collar and bearing land of the shaft to fix the rotor length. The pinned semi-floating bearing with integral thrust faces provides enhanced reaction moments for negative spring forces created by the electric motor in operation and the additional length of the rotor created by the motor.

    摘要: System for controlling an electric assisted turbocharger comprise an electric motor disposed within turbocharger, and an electric motor controller electrically coupled thereto for purposes of controlling the same. A memory is electrically coupled to the electric motor controller and is configured with a condition map that correlates electric motor instructions with engine and turbocharger conditions. The system includes sensors that are electrically coupled to the electric motor controller, and that are configured to sense conditions of at least one of the turbocharger and the internal combustion engine that is coupled thereto. The electric motor controller is configured to control the electric motor based upon the input received from the plurality of sensors as compared to the data contained multi-dimensional condition map. The system provides electric motor speed control, boost pressure control dampening, and can be used to produce electricity from the electric motor depending on the particular operating condition.
