초록

The aim of this paper is twofold: The one is to design BLDC motors for an electric bicycle and the other is to develop a controller of the BLDC motors. A new BLDC Motor has a permanent magnet rotor in which the magnetic arrangement is radial to the shaft and integral to the rotor laminations instead of mounted on the perimeter of the rotor. This technique concentrates flux, giving a higher flux density than a surface-mounted PM motor and has the increase of reluctance torque. The stator of BLDC motor has parallel winding instead of interconnected wye-connection winding, allowing multi-phase separate independent controllability. It gets much more high power than wye-connection at same low voltage. The proposed controller has a technique of exited with modulation(EWM) and one H-bridge and two photo sensors per phase. Experimental results show the performance of the proposed BLDC motors for an electric bicycle.
