Linear Drive Travel System and Automobile

摘要

To enable control the number of revolutions of a wheel with a new structure different from an induction motor and adjust the maximum torque rapidly and accurately. A linear drive travel system includes a metal wheel 20 having a drum rotor and a stator 30 arranged inside the metal wheel 20. The stator 30 includes a plurality of rows of electromagnets 32 arranged in the direction of rotation axis, each row being formed of a plurality of electromagnets 32 arranged along the circumference around a rotary shaft 40. A drum rotor includes a plurality of arc-shaped rotor cores 23 arranged along the circumference around the rotary shaft 40. Control means (control system 80) performs control by allowing electromagnets 32 in some rows to be a magnetization coil of the rotor core and by allowing the electromagnets 32 in other rows to be a rotation coil of the drum motor.
