Insulating motor housing

1. An insulating motor housing comprising:

a plurality of power supply elements each of which is made of flat conductive metal and having an opening, and being provided with a power source terminal for connection to a power source and a plurality of coil terminals for energizing motor coils; and

a resin housing body for holding the power supply elements and for providing insulating material in a space between adjacent power supply elements,

wherein the power supply elements are stacked in the housing body in their thickness direction to be spaced and insulated from each other by said insulating material and integrated with the housing body by insert molding, such that said insulating material is an integral portion of the resin housing body, and

wherein a power source connecter for supplying power to the power source terminals of the power supply elements is integrated with the housing body and the power source terminals of the power supply elements function as connector terminals of the power source connector, and protrude from the openings in the power supply elements in the stacking direction of the power supply elements.

2. The insulating motor housing of claim 1 , wherein

electrical component terminals for connection to an electrical component are integrated with the housing body by insert molding and an electrical component connector for connection to a controller of the electrical component is integrated with the housing body and

the electrical component terminals function as connector terminals of the electrical component connector.

3. The insulating motor housing of claim 1 , wherein

electrical component terminals for connection to an electrical component are integrated with the housing body by insert molding,

the power source connector is configured as a dual-purpose connector for supplying power and connecting the controller of the electrical component and

the power source terminals and the electrical component terminals function as connector terminals of the dual-purpose connector.

4. The insulating motor housing of claim 1 , wherein

the power supply elements consist of ring-shaped elements and

the power source terminals of the power supply elements penetrate holes of the ring-shaped power supply elements and protrude from the power supply elements in the stacking direction of the power supply elements.

5. The insulating motor housing of claim 4 ,

the ends of the coil terminals of the power supply elements protrude radially outward from outer rims of the power supply elements.

6. The insulating motor housing of claim 4 , wherein

the ends of the power source terminals of the power supply elements are bent outward in the radial direction of the power supply elements to protrude from the outer rims of the power supply elements.

7. The insulating motor housing of claim 1 , wherein

the power supply elements include a first power supply element consisting of a ring-shaped element and having a plurality of coil terminals protruding radially outward from an outer rim of the first power supply element and second to fourth power supply elements consisting of ring-shaped elements and being sequentially stacked to be spaced from the first power supply element and insulated from each other,

each of the second to fourth power supply elements includes a power source terminal extending upward in the stacking direction from part of an inner rim of the power supply element and a plurality of coil terminals extending downward from an outer rim of the power supply element, being bent radially outward at its end on a level perpendicular to the stacking direction and flush with the coil terminal of the first power supply element and being arranged to have different phases.

8. The insulating motor housing of claim 1 , wherein each of the power supply elements is a one-piece component and does not have any joints.
