| Stator core

A stator core is made out of a large number of electromagnetic steel plates built up in a stamping die and riveted together. By winding a coil around it, the stator becomes an electromagnet, and rotational force is generated in the rotor. Yutaka leveraged its highly developed press molding technology, used in the mass production of its mainstay torque converter and other products, and began mass production of stator cores.

| Rotor

There are two types of motors used in hybrid electric vehicles, one for driving and one for generating electricity, with the type of motor used varying according to the hybrid system. The rotor is an important part that constitutes the rotation axis of the motor. The drive rotor converts electricity stored in the battery into driving force to move the vehicle, while the electricity generation rotor transmits the rotational force from the engine and during regenerative braking into the motor, where it is converted into electricity.
