PROBLEM TO BE SOLVED: To provide a controller which secures its insulation performance, according to the change of atmospheric pressure, for the insulation performance of the insulator of an electric apparatus deteriorates since the permittivity of the air rises in highlands. SOLUTION: A controller sets the voltage to be supplied to a motor and electric apparatus which supplies the motor with power, according to the detected atmospheric pressure, and controls the motor, based on the set voltage.
