In this paper, non-rare earth traction motor for electric vehicles is discussed. Almost all HEV's and EV's use rare earth permanent magnet motor as a traction motor. The authors have proposed novel induction motor made of Soft Magnetic Composite (SMC) for the resource crisis of rare earth materials. Comparison of iron loss characteristics of SMC induction motor and conventional laminated induction...
Since the efficiency is very important in automotive applications, in this paper a new minimum-copper-loss control scheme, over full speed range for an IPMSM drive used for hybrid electric vehicle application under both current and voltage limits is presented. This paper presents an algorithm to get the smallest current vector command in both field-weakening and deep field-weakening regions for a...
In most conventional EV applications, a central high speed electric motor is mechanically coupled to the wheels by a single speed reduction gearbox and a mechanical differential. An innovative alternative utilizes low speed, high torque, gearless, electric motors, mounted completely inside the rim of the wheels, to provide instantaneous torque and eliminate driveline transmission losses. These in-wheel...
