Motor Integrated Permanent Magnet Gear with a Wide Torque-Speed Range Conference Paper uri icon

abstract

  • This paper present a new motor integrated permanent magnet gear with a wide torque-speed range. In the paper a 35 kW permanent magnet motor with a base speed of 4000 rpm and a top speed of 14000 rpm is integrated into a permanent magnetic gear with a gearing ratio of 8.67. The design process of the combined unit is described together with a description of the construction of the part for a test model. The unit is unique in the sense that it has superior traction characteristics and a torque density of 130 Nm/l which is more 1.5 times of other reported motor integrated permanent magnet gears. The unit may be useful as a direct drive wheel motor for EV's and no liquid cooling system is required. 2009 IEEE.
