Abstract
(EN)
A device and a method for controlling a brushless direct current (BLDC) motor, according to an embodiment of the present invention, comprise: a BLDC motor using a three-phase power source; a current measuring unit for measuring a current corresponding to the three-phase power source; a temperature sensor for measuring the temperature of the BLDC motor; and a control unit for generating a control pulse for supplying the three-phase power source to the BLDC motor, wherein the control unit regulates the control pulse on the basis of the temperature of the BLDC motor, measured by the temperature sensor, so as to regulate switching of the three-phase power source, and regulates the control pulse according to a first technique when the measured temperature is lower than a reference temperature, and regulates the control pulse according to a second technique which is different from the first technique when the measured temperature is higher than the reference temperature.
