摘要： An electromagnetic suspension apparatus for an automotive vehicle, employs an electromagnetic actuator interleaved between a sprung mass and an unsprung mass and arranged in parallel with a suspension spring element, and an electric motor built in the electromagnetic actuator for driving the electromagnetic actuator. A motor controller calculates a displacement input, such as a suspension stroke acceleration and a suspension velocity, transmitted to the electromagnetic actuator, and controls the motor to bring a suspension damping force closer to a desired damping force suited for the displacement input. The motor controller calculates an internal inertia force of the electromagnetic actuator, and corrects or compensates for a motor output by the internal inertia force of the electromagnetic actuator.

摘要： An electromagnetic suspension system for a vehicle, comprises an electromagnetic actuator interposed between a sprung mass and an unsprung mass and disposed substantially in parallel with an spring element. An electric motor is provided for driving the electromagnetic actuator. A motor controller is configured to calculate a displacement input applied to the electromagnetic actuator and to control the electric motor in a manner that the electromagnetic actuator generates an optimum damping force corresponding to the displacement input. A motor control circuit is provided for the electric motor, through which the electric motor is connected to the motor controller. Additionally, an electrical damping element is electrically connected to the motor control circuit and in parallel with the electric motor to generate a damping force in a passive manner under a dynamic braking of the electric motor in response to the displacement input to the electromagnetic actuator from the unsprung mass.
