Abstract
A compressor includes: a motor that includes a rotor including opposed magnets; a compression unit that compresses a refrigerant; and a crankshaft that is connected to the motor and the compression unit and is configured to transmit rotational driving of the motor to the compression unit, wherein the magnets are arranged such that the difference in magnetic force between the opposed magnets eliminates a force that deflects the crankshaft when the motor is rotationally driven.
