Motor driven compressor
View Patent ↗A motor driven compressor having a motor for driving a compression mechanism includes a connecting portion for connecting between an external terminal for supplying electricity to the motor and a wire end portion of a stator of the motor. The connecting portion is located above the motor and the compression mechanism. Further, the connecting portion is formed on the stator housing which accommodates the motor and the stator. The connecting portion is disposed in a hollow projection portion, which extends upward from the housing. Accordingly, the motor driven compressor which is readily manufactured, may avoid a leakage current by insulating a terminal portion of the motor from the housing of compressor.
1. A motor driven compressor having a motor for driving a compression mechanism comprising:
a connecting portion for connecting between an external terminal for electric supply to said motor and a wire end portion of a stator of said motor, said stator being fixed;
wherein said connecting portion is located above said motor and said compression mechanism, and is formed on a stator housing which accommodates said motor, and wherein said connecting portion is sealed to the exterior of said motor driven compressor and arranged in a hollow projection portion which extends upward from said stator housing,
said motor driven compressor further having a hybrid compressor comprising:
a first compression mechanism, configured to be a scroll-type compression mechanism, and driven by a first drive source separate from said motor; and
a second compression mechanism, configured to be a scroll-type compression mechanism, and driven by said motor as a second drive source, and
wherein a first scroll of said first compression mechanism and a second fixed scroll of said second compression mechanism are disposed to extend in opposite directions from a common valve plate.
2. The motor driven compressor of claim 1 , wherein said first fixed scroll and said second fixed scroll are integrally formed.
3. The motor driven compressor of claim 1 , wherein said first drive source comprises an engine for driving a vehicle.
4. A hybrid compressor comprising:
a first compression mechanism which is driven by an engine for driving a vehicle, and a second compression mechanism, which is driven by a motor; and
a connecting portion for connecting between an external terminal for supplying electricity to said motor and a wire end portion of a stator of said motor;
wherein said connecting portion is located above said motor and said first and second compression mechanism, and
wherein each of said first and second compression mechanism is a scroll-type compression mechanism, wherein a first fixed scroll of said first compression mechanism and a second fixed scroll of said second compression mechanism are disposed to extend in opposite directions from a connection valve plate.
5. The motor driven compressor of claim 4 , wherein said first fixed scroll and said second fixed scroll are integrally formed.
