Axial flux ironless permanent magnetic synchronous motor (AFIPMSM) is a new permanent magnetic motor. It has many advantages, such as little volume, low mass, low lost, high power density, no cogging torque, and the sinusoidal back EMF. It gradually becomes the good choice in drive system. However, because of the coreless structure and the long air gap, the winding inductance is small, which ca...

This paper demonstrates the detailed analysis of Proportional-Integral (PI) controller and Fuzzy Logic controller for speed control of a Permanent Magnet Brushless DC (PMBLDC) motor for different speed commands and varying load torque conditions. Implementation of PI controller in closed loop conditions is done. Analysis of classical tuning methods to obtain best PI parameters for speed control...

Recently, many optimal designs for axial flux permanent magnet (AFPM) motors were performed based on finiteelement (FE) analysis. Most of the models are based on reduction of 3D problem to 2D problem which is not accurate for design aspects. This paper describes an accurate electromagnetic analysis of a surface mounted, 28 pole AFPM with concentrated stator winding. The AFPM is modeled with thr...

The Axial Flux Permanent Magnet (AFPM) motor represents a valid alternative to the traditional radial flux due its compact structure; it is suitable for in-wheel applications so that transmission gear can be suppressed. modeling of purely Three-Dimensional (3D) problem and use 3D finite element tools allows attainment accurate results taking also into account effects end-windings. Moreover, mul...

The demand for electric bikes has been increasing in recent years, and so their drive, which requires a high power-to-weight ratio or power density. An axial-flux permanent magnet motor with Halbach-array is an excellent choice bike drives thanks to its known characteristics of density, reliability, efficiency. However, because machine topology not common, the manufacturing process can be chall...

Abstract The axial flux permanent-magnet synchronous motor with amorphous alloy stators has the advantages of high power density, efficiency, large starting torque. But PMSM poor performance in heat resistant and radiation. And electromagnetic loss a significant impact on in-wheel motor’s generation. To demonstrate influence winding coils PMSM, mathematical model thermal transformation was foun...
