ABSTRACT:
A vehicle suspension uses actuators between sprung and unsprung masses, each actuator comprising a brushless dynamoelectric machine having a low inertia rotor engaged with a rotary/linear motion converter or conversion between dynamoelectric machine torque and linear actuator force. A control circuit for each machine applies current from an electric power source to the dynamoelectric machine in response to rotor position sensors and an input control signal to produce a desired actuator force providing motoring or generating action by the dynamoelectric machine. A common supply bus connecting the electric power source and dynamoelectric machines allows the dynamoelectric machines in generating mode to provide electric power to the dynamoelectric machines in motoring mode. Transient storage capacitors across the supply bus, current limiting from the supply bus to the storage battery, a dump resistance and dump switch responsive to battery voltage, and a supplementary alternator are also provided.
