Improved rotor structure design of concentrated flux type ferrite magnet motor for dual clutch transmission

摘要

Dual Clutch Transmissions (DCTs) are providing the full shift comfort of traditional step automatics but offer significantly improved full efficiency and performance. With up to 15% better fuel efficiency compared to planetary-ATs, the DCTs are the first automatics to provide better values than manual transmissions. Therefore, DCT system has been developed competitively on the automotive industry, then development of electric actuator (motor) for DCT system has been important. In this paper, the improved design of concentrated flux type ferrite magnet motor using segmented rotor core is presented. This design can minimize a motor size with maintaining motor performances. Then it is compared with manufactured motor in perspective of its performance.
