Nowadays, various suspension control technology have been developed such as active suspensions, active stabilizers. As an alternative to hydraulic actuator for suspension, electromagnetic device have been developed. Electromagnetic devices are attracting many researchers' attentions by their high responsiveness, controllability, energy saving performance, and so on. Besides these advantages, electromagnetic devices can be connected to each other very easily. Therefore, the authors focus on this characteristic of electromagnetic device and propose a method to use linked two electromagnetic devices as a roll stabilizer. Then the automobile can stabilize its rolling performance without a roll stabilizer, which increases the mass of the car body. Through basic experiments with two motors and control circuit, the performance of proposed system is examined. The results indicate the linked electromagnetic devices can be operated as the roll stabilizer. Numerical simulations of the turning automobile is carried out, and the results indicate the proposed system is effective.
