ELECTRONIC CIRCUIT DEVICE FOR CONTROLLING BRUSHLESS MOTOR AND MANUFACTURING METHOD THEREFOR

PROBLEM TO BE SOLVED: To provide an electronic circuit device capable of controlling an output of a brushless motor with ease by means of various methods by using a simple circuit and low cost parts as much as possible. SOLUTION: This is the electronic circuit device which controls the output of the brushless motor. In the first method, the output is controlled by shortage or open in a connector pin fitted in the electronic circuit device, in the second method, the output is controlled by the position of the connector pin which is connected with DC power, in the third method, the output is controlled by changing a voltage applied to the connector pin, and in the fourth method, the output is controlled by changing a duty ratio of a pulse voltage applied to the connector pin. In this electronic circuit device, jumper connection is shorted or opened, or a small number of parts are added in a substrate in which common parts are mounted on a common printed circuit board.
