Abstract: A new type of self bearing motor that uses Lorentz type forces to generate both bearing force and motoring torque has been developed. The motor stator is of slotless construction with four, three phase windings. The motor rotor is constructed of 16 surface mounted permanent magnets (PM’s). The main advantage of the design is that it eliminates the tradeoff between motoring torque and bearing force with PM thickness as found in previous designs. This paper presents the dynamic model for the self bearing motor a…
