Abstract:
An electric compressor 10 includes a compression mechanism 11, an electric motor 12 driving the compression mechanism 11, and a control portion 13 controlling to drive the electric motor 12, incorporated into a single casing, and further includes a temperature detector 14 detecting a temperature of one or more components constituting one or both of the control portion 13 and the electric motor 12, and a current detector 15 detecting a current flowing through the component. When the temperature detected by the temperature detector 14 is a temperature Td, the current detected by the current detector 15 is a current Id, and a current corresponding to the temperature Td at a temperature characteristic relating to the current specific to the component is a current Ia(Td), the control portion 13 stops driving the electric motor 12 on the basis of a result of comparison between Ia(Td) and Id.
