چکیده :

This article studies three new toothed consequent-pole flux-reversal permanent magnet (FRPM) motors, each with specific combined PM arrays. The PM arrays comprise the biased-flux (BF) and flux-reversal (FR) effects. The FR effect is added mainly to boost the output torque production, and applying a magnetic-equivalent circuit (MEC) shows that the BF effect lowers the saturation risk in the stator core. Also, using finite element analysis (FEA), the main proposed motor generates the sinusoidal back-EMF waveform with an RMS value of 11.3V. Additionally, the full-load results show that the proposed motor produces 1.76N.m torque with 3.5% ripple. Furthermore, the flux density distribution of motors shows the importance of the BF effect in overload performances and verifies the analytical MEC results.
