Abstract

An interconnection device for providing an electrical connection between a motor and an inverter is disclosed. The interconnection device comprises a base member having a first receiving aperture arranged relative to a second receiving aperture, and a mounting interface that provides for direct coupling of the base member to the motor. A substrate is coupled to the base member and comprises a first connector assembly, a second connector assembly, and integrated electronic circuitry arranged thereon. The first connector assembly is coaxially aligned with the first receiving aperture of the base member and arranged to receive a plurality of motor pin connections. The second connector assembly comprises a plurality of connection elements arranged to transmit and receive power and signal connections for powering and controlling the motor.

First claim

What is claimed is:

1. An interconnection device for providing an electrical connection between a motor and an inverter, the interconnection device comprising:
a base member comprising a first receiving aperture arranged relative to a second receiving aperture, and a mounting interface that allows for direct coupling of the base member to the motor;
a substrate coupled to the base member; the substrate comprising a first connector assembly, a second connector assembly, and an electronic circuitry arranged thereon; wherein the first connector assembly comprises a plurality of first connection elements configured to transmit and receive power and communication signals for powering and controlling the motor, and wherein the second connector assembly comprises a plurality of second connection elements each comprising a cylindrical body having an inner annular surface defining a conductive channel sized to receive one motor pin connector of a plurality of motor pin connectors, wherein the plurality of second connection elements are aligned with the second receiving aperture of the base member.

2. The interconnection device of claim 1 , wherein the second receiving aperture is configured to receive the plurality of motor pin connectors and the first receiving aperture is configured to receive at least a portion of a shaft of the motor.

3. The interconnection device of claim 1 , wherein each second connection element of the plurality of second connection elements is configured to receive a cylindrical motor pin connector of a plurality of cylindrical motor pin connectors.

4. The interconnection device of claim 1 , wherein the electronic circuitry comprises one or more integrated circuit chips mounted to a surface of the substrate via at least one of the following bonding techniques: soldering, wire bonding, adhesive bonding, flip chip bonding, bumping, or tape automated bonding.

5. The interconnection device of claim 4 , wherein the interconnection device comprises one or more sensors arranged on a first or second surface of the substrate.

6. The interconnection device of claim 1 , wherein the substrate is configured for removable insertion into a grooved channel formed in the base member.

7. The interconnection device of claim 1 further comprising a cover apparatus that is sized to enclose the substrate and the base member, and for removable coupling to the motor.

8. The interconnection device of claim 7 , wherein the cover apparatus comprises a heat dissipation element integrally or removably coupled to the cover apparatus, wherein the heat dissipation element is arranged such that excess heat generated by the interconnection device is dissipated through the cover apparatus.

9. The interconnection device of claim 7 , wherein the base member comprises at least one alignment protrusion and the cover apparatus comprises at least one alignment recess configured to matingly engage the at least one alignment protrusion of the base member.

10. The interconnection device of claim 1 , wherein each of the plurality of connection elements associated with a respective one of the first connector assembly and the second connector assembly are arranged to extend in a direction generally orthogonal to a planar surface of the substrate.
