摘要
An inverter device for controlling a BLDC motor according to the present invention includes a rotation speed detector for detecting the rotation speed of the BLDC motor, and a rotation speed value for a predetermined time prior to a current time through the detected rotation speed to accumulate and store A storage unit, receives the current rotation speed value received from the rotation speed detection unit and the accumulated rotation speed value stored in the storage unit, and assigns a predetermined weight to the current rotation speed value and the accumulated rotation speed value to obtain a control speed value It includes a control speed determination unit to calculate, and a control unit for controlling the rotation of the BLDC motor according to the calculated control speed value. Accordingly, it is possible to correct an error due to cogging torque generated in the BLDC motor in a low-speed operation situation.
