Description

Technical field

[0001] The present invention relates to a rotor of a spoke-type motor and a manufacturing method thereof. In particular, it relates to a spoke-type motor rotor and a manufacturing method thereof, which can improve the performance of the motor by installing a non-magnetic yoke ring and improve the mounting performance of the rotor in a spoke-type motor. Background technique

[0002] Under normal circumstances, in the magnetic field of the motor, the conductor and the magnetic field are placed vertically. If the current passes, the electronic induction phenomenon that generates the rotational force in the vertical direction in the magnetic field is used. According to the type of power source, it is divided into DC motors and AC motors.
