The bearingless brushless DC motor (BBLDCM) was a strongcoupled nonlinear system. To solve the problems of suspension system precise control and rotor jitter, a novel direct suspension force control strategy was proposed. With the reference of direct torque control of traditional brushless DC motor and the operating characteristics of the BBLDCM, the suspension force vector under different conditions was derived, the suspension winding conduction table was given, and the working process of the novel direct suspension force was clarified. Finally, the suspension control system was designed and simulated by Simulink. The simulation results showed that the rotor could be suspended stably, and the rotor jitter was weakened effectively. In addition, this method improved the control accuracy of the suspension system.
