Abstract
In a compressor, an inverter control device that performs an inverter control on an electric motor is integrally provided on a body portion of a container which houses a compression mechanism and the electric motor which are axially arranged in a line. The inverter control device is connected to the electric motor to shorten the distance of wiring from the inverter device to the motor to allow the reduction in weight, the reduction in a space to be required for the installation, and the reduction in the amount of noise.
Claims20
A compressor with a built-in electric motor, comprising:
- a compression mechanism;
- a built-in electric motor that drives the compression mechanism;
- a container that houses the compression mechanism and the built-in electric motor;
- and
- an inverter control device that performs an inverter control on the built-in electric motor, the device being integrally provided on a part of the container and connected to the electric motor;
- wherein the inverter control device comprises an electrode part and an inverter part which are electrically connected to each other, the electrode part is opposite to a high pressure portion of the container, and the inverter part is opposite to a low pressure portion of the container.
