Abstract:
An electric compressor includes a compression portion discharging a high pressure refrigerant by compressing a low-pressure drawn refrigerant, an electric motor driving the compression portion with a rotation of a rotor, a motor drive circuit driving the electric motor, an intermediate pressure port through which an intermediate pressure refrigerant is introduced into the compression portion, and a controller performing a rotation control of the rotor. When the controller stops the electric motor in a two-step compression mode in which the intermediate pressure refrigerant is introduced into the compression portion, the controller stops the rotor rotating by performing short-circuit braking on the electric motor and then fixes a rotational position of the rotor at a predetermined rotational position by performing direct current excitation on the electric motor.

Claim (Index 9):
The electric compressor according to  claim 3 , wherein when a predetermined time has elapsed from a time of starting the direct current excitation, the controller determines that the pressure of the intermediate pressure refrigerant has decreased to the pressure level incapable of causing backward rotation of the rotor.
