Abstract

The present invention relates to a rotor and a method of manufacturing a rotor. The rotor includes: a rotor assembly including a magnet and a rotor core; and a molding part including a first molding part that is firstly injection-molded to support the rotor assembly in which the magnet is not yet magnetized and a second molding part that is secondly injection-molded to support the rotor assembly in which the magnet is magnetized.

Description

technical field [0001] The present invention relates to a rotor manufactured by double injection molding to facilitate magnetization and a method of manufacturing the rotor. Background technique [0002] A motor is a device that obtains rotational force from electrical energy, and includes a stator and a rotor. The rotor is configured to electromagnetically interact with the stator and is rotated by a force acting between the magnetic field and the current flowing in the coil. [0003] Permanent magnet motors that generate a magnetic field using permanent magnets may be classified into surface mount permanent magnet motors, interior type permanent magnet motors, and spoke type permanent magnet motors. [0004] Among these, the spoke type permanent magnet motor can generate high torque and high output due to a structurally high magnetic flux density, and can miniaturize the motor with respect to the same output. Spoke-type permanent magnet motors can be applied to drive mot...
