Abstract With the reference of direct torque control of conventional permanent magnet synchronous motor, a novel direct levitation force control algorithm based on space vector pulse width modulation method is proposed in this paper. To control radial magnetic levitation forces in permanent magnet-type bearingless motors directly, a profound theoretical analysis on mechanism of direct force control is presented and a real-time levitation force and torque control system is also designed. The experimental results of a consequent-pole permanent magnet bearingless machine show good performance of static and dynamic suspension and confirm the validity and availability of this new arithmetic.

Key words： Consequent-pole permanent magnet motor bearingless motor space vector pulse width modulation (SVPWM) levitation force direct control
