| 摘要 | A control device (2) includes a shot-pulse control unit (5) that provides, at a time of starting a synchronous motor (3), a predetermined current to each phase of the motor stator (3) for a short time; a detecting unit (6) that detects a current flowing through each phase; an estimating unit (7) that estimates a position of the motor rotor by comparing detected values; a voltage control unit that controls application of a voltage to the synchronous motor (3) based on a high-pressure side pressure of the compressor when the compressor is failed to be started due to any cause; and a magnetism-resistant section having a conductive layer sandwiched by insulating layers. The magnetism-resistant section covers a portion of a substrate of the control device, and a portion at which the conductive layer is exposed is in contact with, the housing or a part conducting heat to the housing. | ||||||
