A varnish impregnation device including: a lower housing in which a stator is seated in an internal space thereof, the stator including a stator core which has a plurality of teeth protruding inward or outward and has a slot that is a space between the teeth. A coil winding passes through the slot and is wound around the teeth. A second cover member is coupled to an upper outer portion of the stator core. The lower housing has a plurality of varnish supply holes which is formed to pass up and down through a lower surface thereof, and the plurality of varnish supply holes communicates with the slot.

Disclosed are a system and method for manufacturing a Halbach array rotor.

A system for manufacturing a Halbach array rotor according to an embodiment of the present disclosure includes a magnet pre-magnetization device configured to seat non-magnetized magnets on holders radially disposed on an index, pre-magnetize the individual magnets by using automation devices installed for respective rotation sections in one side rotation direction, and then load the magnets to a hub, a clamping jig device configured to couple the hub to a circular arrangement jig and fix the individual magnets loaded onto an outer peripheral surface of the hub by using corresponding magnet clamping units, and a controller configured to magnetize the non-magnetized magnets in accordance with orientations by collectively controlling the magnet pre-magnetization device and the clamping jig device and then assemble the magnetized magnets on the hub in accordance with a magnetization direction of a Halbach array.

The present invention relates to a rotor of a motor and a manufacturing method therefor. The rotor of a motor of the present invention includes: a rotor core including a first stage core to an n-th stage core each coupled to a rotation shaft; and permanent magnets coupled to the first stage core to the n-th stage core, respectively, wherein a plurality of magnetic steel plates of the first stage core to the n-th stage core each include a guide slot into which a guide pin is inserted to guide a permanent magnet provided in each of the first stage core to the n-th stage core to form a preconfigured skew angle, the guide slot is provided inside the plurality of magnetic poles along a radial direction, the guide slot includes a first guide slot, a second guide slot, and a third guide slot spaced apart from each other along a circumferential direction, and the first guide slot, the second guide slot, and the third guide slot are each configured to be arranged at a position forming a preconfigured angle with respect to the center of an outer magnetic pole in a radial direction. As such, the permanent magnets may be arranged to form the skew angle and the magnetic steel plates of the plurality of rotor cores divided in an axial direction may have a unified shape.
