| Abstract |
Permanent magnet synchronous machines (PMSM) have compared with asynchronous engines a better utilization factor (torque per mass), a better power factor and a higher efficiency especially when high energy magnets (rare-earth-materials such as NbFeBo or SmCo) are used. The price of the magnets is still a major cost-factor of the machine, but the price decreases considerably when advanced and cost-optimized mass-production procedures are used in magnet production. Therefore it is reasonable to use this type of machine for new applications e.g. in electric cars (zero emission vehicles), boats or micro-power-stations as well. At the research department of the University of Leoben detailed investigations about this type of electrical machine has been done (including prototyping and testing). Motors for different applications and in a variety of nominal powers have been developed in cooperation with industrial partners. One of the main objectives is to optimize the machine for the mentioned applications. This paper describes an optimization of the motors geometries with respect to cost, weight and efficiency for usage in electric vehicles. |
