Motor-driven compressors
View Patent ↗A motor-driven compressor includes a housing having a compression portion for compressing refrigerant, a motor for driving the compression portion, and a drive circuit for controlling the motor. A connection member having a plate shape is disposed at one end of the motor. The connection member connects a plurality of coils of the motor to the drive circuit. In such motor-driven compressors, because the rolling and bundling of electrical wires extending from coils to connect the drive circuit are not necessary, the size of the motor-driven compressor may be reduced.
1. A motor-driven compressor comprising:
a housing for introducing refrigerant and discharging the refrigerant;
a compression portion for compressing the refrigerant, wherein said compression portion is disposed within said housing;
a motor for driving said compression potion, wherein said motor is disposed within said housing;
a drive circuit for controlling said motor; and
a connection member having a plate-shape, disposed at one end of said motor for connecting a plurality of coils of said motor to said drive circuit, wherein said connection member includes an insulating material, and a conductive member is encased within said insulating material of said connection member, and wherein said connection member further comprises a refrigerant aperture formed through said connection member to form a flow route of the refrigerant.
2. The motor-driven compressor of claim 1 , wherein said connection member has a plurality of motor-side connection portions to connect said plurality of coils of said motor, and each said motor-side connection portion is disposed at a position corresponding to each said coil of said motor.
3. The motor-driven compressor of claim 2 , wherein said plurality of motor-side connection portions is formed at said conductive member of said connection member.
4. The motor-driven compressor of claim 1 , wherein said connection member has a plurality of drive circuit-side connection portions to connect a plurality of terminals of said drive circuit, and each said drive circuit side connection portion is disposed at a position corresponding to one of said terminals of said drive circuit.
5. The motor-driven compressor of claim 4 , wherein said plurality of drive circuit-side connection portions is formed at said conductive member of said connection member.
6. The motor-driven compressor of claim 1 , wherein said connection member is fitted with a plurality of engaging members, which secure said connection member to one end of said motor.
