Abstract

Provided is a scroll-type electric compressor capable of promptly decreasing pressure inside a scroll compression mechanism to smoothly and efficiently prevent reverse rotation and reduce noise when a motor is stopped. A control deviceexecutes deceleration control of switching elements to decrease the rotation speed of a motorafter having received an instruction to stop the motor, and brake control of stopping a rotorof the motorat an angle at which a back pressure hole of a movable scroll is not closed or an angle at which a discharge hole of a fixed scroll is not closed after the rotation speed of the motorhas been decreased by the deceleration control and switching the switching elementsA toF to fix the rotor at the angle.
