Abstract

This paper presents the physical construction and test results of two new demonstrators of a motor integrated permanent magnet gear (MIPMG), which is a second version of an already tested demonstrator. The demonstrators will be used as traction units for a battery electrical vehicle and the background for the specifications are elaborated. Simulated and measured results of rotational losses of the first and second versions are compared. The efficiency of the new design is investigated and compared with three direct-drive motors in a few operating points, and the MIPMG v.2 seems superior when used as a traction unit in urban traffic.
