Since the collar 17 is required to seal the end of the frame 15 and the can 3, the collar 17 and the spigot fitting part of the frame 15 end and the collar 17 and the bracket 1 are required.
It is necessary to machine the spigot fitting portions 8 and 19, and it is also necessary to assemble these parts, so the manufacturing cost is high.

が、レジンモールド部材の内周に設けてもよい。 Numeral 6 is a plurality of screws embedded in the resin mold member 4 for tightening a bracket 10, which will be described later. Numeral 7 is a rotor, which is composed of a rotor shaft 8, a rotor core 9, etc. . Reference numeral 10 denotes a resin molded boss portion 101 fixed to the resin molded member 4 with a bolt 11, which is inserted into the can 3 and is inserted into an annular groove 1 facing the tip of the can 3.
02 is provided. 12 is an elastic ring such as an O-ring, which seals the interface between the can 3 and the mold member 4. 13 is a sleeve bearing, and 14 is a housing cover. A lubricant (antifreeze) such as propylene glycol is sealed inside the can. Although the annular groove 102 has been described as being provided on the boss portion of the bracket, it may also be provided on the inner periphery of the resin molded member.

としている。 That is, both ends of the can 3 are arranged so that they face between the inner circumferential surface of the resin mold member 4 formed in a cylindrical shape and the boss portions 101 of the bracket 10 that are fitted into both open ends of the resin mold member 4. An annular groove 10 is formed at the end of the can 3.
2, and a seal ring 12 is provided in this annular groove 102, with which the resin mold member 4, the boss portion 101 of the bracket 10, and the end of the can 3 come into pressure contact, thereby perfecting the seal inside and outside of the can 3.

る。 As explained above, the present invention integrally surrounds the outer periphery and sides of the stator core and the periphery of the coil ends with a resin molded member, and directly attaches a bracket having boss portions to both openings of the resin molded member. The mounting structure prevents outside water from entering the stator, and eliminates the need for a stainless steel frame and collar unlike conventional canned types, eliminating the need for machining and assembly. Manufacturing costs are reduced.

止できる。 In addition, since the end of the can faces between the resin mold member and the boss of the bracket attached to both opening ends, and a seal ring is provided at this end position, this seal ring allows the resin mold to be closed. The parts, the boss part of the bracket, and the end of the can are sealed, which prevents deterioration of the electrical insulation properties of the stator coil due to the intrusion of internally sealed water, and also prevents outside water from entering the bracket.
It is possible to prevent the resin from entering between the resin mold members into the motor, that is, the inside of the can and the stator.
