Permanent-Magnet DC Motor Actuators Application in Automotive Energy-Regenerative Active Suspensions 2009-01-0227

An energy-regenerative vehicle suspension is proposed. Permanent-magnet direct-current motors are utilized as the active actuators in automotive suspension. The significant characteristic of the suspension is that vibration energy from the road excitation can be regenerated and transformed into electric energy while good suspension performance can be maintained. The modeling of electrical suspension system has been completed and simulated in Matlab/Simulink. The motor actuator working as a generator is proved to maintain the performance of vibration control and energy-regeneration. The prototype of motor actuator is designed and made. The vibration absorption and regeneration performances are verified by full-vehicle experiments.
