The paper introduced a novel. 1 phase stator Ferrite PM small motor &. drive in order to reduce fabrication and initial motor cost and simplify the inverter control The novel motor has only two stator coils where the PM flux switches polarity in a doubly salient topology with 4 rotor salient poles (4 equivalent pole pairs) FEM is used to characterize the new motor. due to complicated flux lines trajectories and magnetic saturation. The parking position (obtained through airgap tapering) at 27º. allows for sufficient time to start the motor on speed proportional full load torque (0.2 Nm). even in open loop (V f) control within 0.4 seconds to 1600 rpm. Controlled dynamics is investigated through Matlab Simulink with inductance. cogging-torque and emf waveform imported from FEM.
