- the second core part 26 includes a second header part 26a and a second winding part 26b protruding in the axial direction from one surface of the second header part 26a.
- the first core part 24 and the second core part 26 are fabricated by heat treatment after molding with metal powder. One end of the first header part 24a and one end of the second header part 26a come into contact to form a core.
- the carrier part 27 includes an upper carrier 27a and a lower carrier 27b.
- the upper carrier 27a serves to insulate the first core portion 24 from the coil 29 while fixing it to the stator casing 1.
- the upper carrier 27a surrounds the first core part 24 so that one surface of the first header part 25a is exposed at one end of the stator casing 21, and resin is injected so that it is coupled to the stator upper guard 21b. is formed
- the first core part 24 is fixed to the stator upper guard 21b by the upper carrier 27a.
- the upper carrier 27a is ejected so as to protrude in the axial direction so that its inner circumferential surface surrounds the shaft 10 into which it is inserted.
- the lower carrier 27b serves to insulate the second core portion 26 from the coil 29 while fixing it to the stator casing 1. To this end, the lower carrier 27b surrounds the second core part 26 so that one surface of the second header part 26a is exposed at the other end of the stator casing 21, and resin is injected so that it is coupled to the stator lower guard 21b. is formed The second core part 26 is fixed to the stator lower guard 21c by the lower carrier 27b.

Further, the thickness of the core in the width direction is much thicker than the thickness of the core in the axial direction. In this case, since the coil 29 has a flat shape, the gap between the coils 29 can be reduced, so that the density of the winding wire can be increased and the output can be increased. In addition, if the width direction of the core is thicker than the axial direction of the core, the coil 29 can be thickly wrapped around the core, so that an effect can be obtained as if the coil is wound in several stages.
- the coil 29 may be formed as a hollow tube so that cooling water may flow therein. Heat is generated in the coil 29 when current is supplied to the coil 29 and the motor operates. In this case, if the coil 29 overheats, the efficiency of the motor decreases, so the coil 29 needs to be cooled. Therefore, the coil 29 can be cooled by making the coil 29 a hollow tube and allowing cooling water to flow inside the coil 29 .

To this end, the gap stoppers 45a and 45b limit the position of the end of the rotor fixing plate 33 in the axial direction of the shaft 10 when the rotor fixing plate 33 is inserted into the stator means 20. That is, the first interval stopper 45a and the second interval stopper 45b are mounted on the shaft 10 to keep the interval between the magnet 31 and the core constant.
- the other end of the shaft 10 is mounted on the lower lid 40. And fix the first interval stopper (45a) to the other end of the shaft (10) to position the rotor means (30) at a certain point. And when the rotor means 30 is mounted on the shaft 10, the rotor means 30 is supported by the first interval stopper 45a and positioned at a certain point on the shaft 10.

- the rotor middle housing 50 is located between the stator means 20 to accommodate the rotor means 30, and is detachably fixed to the stator casing 20. Even in this embodiment, the rotor middle housing 50 may be fixed with bolts 12. Therefore, in the case of this embodiment, the stator means 20 can be easily expanded in multiple stages.
