MOTOR AND FAN HAVING MOTOR

Japanese Patent JP2018019588

A

PROBLEM TO BE SOLVED: To provide a motor with a low cost, and a fan having the motor.SOLUTION: A fan and a motor thereof are provided. The motor includes a motor drive device. The motor drive device includes a printed circuit board. A control management unit and a voltage converter are arranged on the printed circuit board. The control management unit classifies target rotation speed signals provided by an ECU into multiple rotation speed ranges each corresponding to a specific output duty ratio. The control management unit receives a target rotation speed signal transmitted from the ECU in real time, and outputs a voltage regulating signal, which is a pulse width modulation signal having a duty ratio corresponding to one of the rotation speed ranges within which the target rotation speed signal transmitted from the ECU falls. The voltage converter is connected between a power source and the motor, and is configured to regulate a voltage outputted to the motor in response to the voltage regulating signal having the specific duty ratio outputted from the control management unit, and to regulate a rotation speed of the motor.SELECTED DRAWING: Figure 1
