Optimization of specific power of axial flux permanent magnet brushless DC (PMBLDC) motor based on genetic algorithm optimization technique for an electric vehicle application is presented. Double rotor sandwiched stator topology of axial flux permanent magnet brushless DC motor is selected considering its best suitability in electric vehicle applications. Rating of electric motor is determined...

In this paper, the hairpin method is applied to an Electric Vehicle (EV) driving motor with a stator winding designed round copper wire. The secure high space factor by using wire instead of for winding. applicable model 300kW Interior Permanent Magnet Synchronous Motor (IPMSM), and cooling water cooling. current density has proportional relationship thermal characteristics, in case wire, lower...

The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent Magnet Linear Synchronous Motor (PMLSM) can provide high instantaneous thrust. This paper presents the design and analysis...
