Original Abstract

Basic electric machines in automobiles are starter motors and alternators. Starter is one of the very important electric machines in car, but it operates for very short time only. Therefore the development is focused to the still smaller and lighter machines. Alternator is a basic power supply for automobiles. The minimal power at the moment about 900 W / 14 V. The alternators and starters are improved virtually in two directions: the output is increased, which means new designs or the losses are reduced, which means increasing efficiency. In this way the output taken away from the combustion engine can be reduced and fuel spared. Both directions of the development are the subject of research in the contribution. Apart from that, it is necessary to deal with the possibilities and conditions for using a motor-generator, i.e. one machine used both as a starter and alternator.
