Abstract

The present invention provides an air compressor that reduces a load torque at the time of starting. A compressor (1) includes a compressor body (2), an electric motor (6) that drives the main body (2), and a current supply circuit (21) that supplies a current to the electric motor (6). The circuit (21) is switchable between a steady operation mode in which a rated voltage of a power supply is applied to the electric motor and a start mode in which a voltage lower than the rated voltage is applied to the electric motor. The compressor (1) further includes an intake adjustment valve (100) switchable between an opened state and a closed state, and a controller (20) that controls the modes of the circuit (21) and the opened and closed states of the valve (100) The controller (20) determines whether or not the electric motor (6) reaches a rated rotational speed. The valve (100) is closed and the circuit (21) is set to the start mode for a period from a start time to a steady operation start time when it is determined that a rotational speed of the electric motor (6) reaches the rated rotational speed, and the circuit (21) is switched to the steady operation mode and the valve (100) is opened in synchronization with the switching for a period after the steady operation start time.
