摘要：An electromagnetic suspension system for a vehicle comprises an
electromagnetic actuator (4) interposed between a sprung mass (1) and an unsprung mass (6) and disposed substantially in parallel with a spring element (7). An electric
motor (8) is provided for driving the electromagnetic actuator (4). A motor controller (17) is configured to calculate a displacement input applied to the electromagnetic actuator (4) and to control the electric motor (8) in a manner that the electromagnetic actuator (4) generates an optimum damping force corresponding to the displacement input. A motor control circuit is provided for the electric motor (8), through which the electric motor (8) is connected to the motor controller (17). Additionally, an electrical damping element (20,21) is electrically connected to the motor control circuit and in parallel with the electric motor (8) to generate a damping force in a passive manner under dynamic braking of the electric motor (8) in response to the displacement input to the electromagnetic actuator (4) from the unsprung mass (6).
