Evaluation of the Efficiency of Line-Start Permanent-Magnet Machines as a Function of the Operating Temperature
(IEEE, 2014)The standard squirrel-cage induction machine has nearly reached its maximum efficiency. In order to further increase the energy efficiency of electrical machines, the use of permanent magnets in combination with the robust ... -
Heat-transfer improvements in an axial-flux permanent-magnet synchronous machine
(Pergamon Press, 2014)Axial-flux machines tend to have cooling difficulties since it is difficult to arrange continuous heat path between the stator stack and the frame. One important reason for this is that no shrink fitting of the stator is ...
