DIRECT DRIVEN TRANSMISSION TRACTION MOTOR FOR ELECTRIC VEHICLE INCLUDING CARBON FIBER FABRIC SHAFT

摘要

In a direct driven transmission traction motor for an electric vehicle which includes a stator fixed to a car; a rotator which includes a permanent magnet and is inserted into an axle, provided is a direct driven transmission traction motor for electric vehicle including carbon fiber fabric shaft. The rotator is formed by successively bonding ring-shaped rotor cores. The shaft can be forcibly fitted without damage, and is made of carbon fiber to reduce weight, inertia, to improve response characteristic, flux path structure, and heat dissipation. It is a proper method for optimizing the combination structure of a rotator and a shaft. The combination structure of the rotor and the shaft can prevent safety accident and the cooling property of an driven transmission traction motor. Also, it reduces the weight of the rotator including the shaft, and inertia, improve response characteristic, flux path structure, and heat dissipation.;COPYRIGHT KIPO 2015
