A control device for electric motors, capable of precisely moving one object by using two electric motors based on periodically repeated commands. The control device includes a first learning controller for calculating an amount of correction so that a positional deviation of a first electric motor is minimized, and a second learning controller for calculating an amount of correction so that a positional deviation of a second electric motor is minimized. The first and second learning controllers are independent from each other, and configured to minimize the positional deviation of the corresponding electric motor. The parameters set in the learning controllers, each defining the response of learning control of each electric motor, are equal to each other.
