Improved Design of Outer Rotor Machine in PM Technology for Motor Bike Drive Application

Performance of electric motor is tied to torque which is the amount of turning power. This factor overcomes inertia and sustains acceleration during driving operation for vehicle's long distance travels. High torque motors have the advantage of fast response for performance. Electric propelled vehicles have been accomplished used performance magnet technology which has completely replaced and also reduced the large space usually occupied by combustion engine in motor-bike. This paper presents the improved design (FSM) structure of three-phase 24S-14P flux switching motor with permanent magnet flux source for optimum torque. The initial design structure generated torque of 241Nm which is considered low in maintaining fast torque response driving operation. High torque motor is factor for fast torque response operation. The 2D-finite element analysis by JMAG Designer version 14 is utilized in examining motor's performance in terms of torque and initial torque output has been improved to 348.6Nm, an increase of 107.6Nm. This performance shows and validates permanent magnet FSM with segmented rotor as a viable candidate for optimum torque capable of sustaining acceleration for long driving operation.
