PURPOSE:To prevent generation of an electromagnetic noise by forming the peripheral face of one of the startor inner peripheral face and the rotor outer peripheral face into the shape of out of roundness with the direction of the longest axis and the direction of the shortest axis arranged in a condition perpendicular to each other. CONSTITUTION:The inner peripheral face of a startor 2a of a motor 2 housed inside an enclosed case 1 of a rotary compressor is formed into the shape of out of roundness with the direction of the longest axis L1 and the direction of the shortest axis L2 are arranged so as to be perpendicular to each other. Due to this formation, if the longest axis of the stator 2a is arranged in the direction corresponding to the direction of a position of an opening angle thetaof a discharge valve with respect to a fitting position B of a blade 1 of a cylinder 5 for the compressor, change of load of a compressive element 3 comes to be absorbed by a rotor gap, and operation of the motor in a condition where uniform rotor gaps exist is realized.
