CONTROLLER FOR MOTOR DRIVING COOLING FAN FOR VEHICLE USING SEPARATE HIGH POWER SUPPLY SYSTEM

摘要

According to the present invention, provided is a cooling fan driving motor controller for use in a vehicle that separately provides first power having a relatively high voltage and second power having a relatively low voltage. Provided is a cooling fan driving motor controller which includes a power input and motor driving part (110) for supplying first power as the power of a cooling fan driving motor; and a control part (120) for performing PWM control on the power supplied to the cooling fan driving motor and receiving the second power as operating power.
