We will introduce a drive motor for one-motor SPORT HYBRID system i-DCD, which is optimized for the compact car.
The i-DCD system is equipped in the new FIT3 model, which uses 7-speed DCT (Dual Clutch Transmission) with the built-in motor, and the engine can be disconnected and motor drive engaged in response to driving conditions. The i-DCD system improved fuel efficiency by 18% at the JC08 mode in comparison to the IMA (Integrated Motor Assist) system, which directly links the motor to the engine crank axis.
The motor equipped in the DCT has been reduced in size to fit into the transmission of a compact car. Also, to fulfill system requirements, highly-efficient, high-power motor have been developed using magnetic field analysis technology.
This time, we will go into the details of the applied technology put into motor development and the performance of the motor.
