An apparatus that reduces vibration generation and magnetic leakage, wherein the apparatus is a motor, an articulated serial robot that has a motor built in, a substrate loader that includes the articulated robot, and a related exposure apparatus equipped with the substrate loader. The motor includes a drive shaft to drive the motor; a rotor attached with the shaft; and a stator that opposes the rotor and causes an electromagnetic force to act between the rotor and the stator to drive the drive shaft; an RC stator, for reaction force cancellation attached with the stator; an RC rotor for reaction force cancellation, opposing the RC stator; and a counterweight sleeve attached with the RC rotor, wherein the reaction force, which is applied to the stator via the drive shaft when the counterweight sleeve rotates in a direction opposite that of the drive shaft, is cancelled.
