Magnetic flux leakage modelling and optimisation of a CRAHMB for DC motor

In this study, a combined radial–axial hybrid magnetic bearing (CRAHMB) with four poles is designed for high-speed brushless DC motor. Owing to the small distance of radial and axial unit of CRAHMB, the magnetic flux leakage (MFL) in both radial and axial directions is complex and serious. This stud...
