Abstract
Disclosed is a canned motor for restraining a cogging torque from being generated by inserting magnetic metal pins into slot openings of a stator, thereby reducing noise and vibrations during an operation of the canned motor. The canned motor includes: a can inserted into a housing to seal a coil mounted within the housing; and a stator installed on an outer peripheral surface of the can and inserted along an inner peripheral surface of the housing. A plurality of fixing guides protrude from an outer peripheral surface of the can and metal pins are inserted into the fixing guides to be integral with the fixing guide, such that the metal pins are inserted into and attached to slot openings of the stator when inserted into the stator.
