Abstract

PURPOSE:To reduce the heating value of each driving element, to improve heat radiation efficiency and to miniaturize a radiator by connecting plural driving elements consisting of power MOSFETs in parallel. CONSTITUTION:In a control device 10 for a motor 4, a feeding circuit 11 is provided with the driving elements 12a, 12b consisting of power MOSFETs. Respective driving elements 12a, 12b are fitted to the radiator 20. A microprocessor 15 computes the objective rotational frequency of a motor 4 on the basis of an input signal to a room temperature setter or the like and then computes its duty ratio. A pulse signal indicating the duty ratio is outputted to the gates of the driving elements 12a, 12b to control the ON/OFF of the elements 12a, 12b. Thereby, the motor 4 is rotated at the objective rotational frequency and a blower 1 goes to an optimum blowing state.
