BLDC MOTOR DRIVEN BY COMPENSATING FOR ERRORS ACCORDING TO ATTACHMENT POSITION OF HALL SENSOR AND CONTROL METHOD THEREOF

摘要

Disclosed are a BLDC motor driven by compensating for errors according to an attachment position of a hall sensor, and a control method thereof. The disclosed BLDC motor comprises: a motor which includes a stator and a rotor, and of which driving is controlled for each section; hall sensors which detects the position of the rotor; a control unit which calculates a control signal for driving the motor based on hall signals output from the hall sensors, respectively; and a driving unit which drives the motor according to the control signal. The control unit calculates the operation time of previous sections based on the hall signals, calculates the operation time of a current section by averaging the operation times of the previous sections, and calculates the control signal of the current section based on the operation time of the current section. The operation time of each of the previous sections is calculated based on the operation time of a section just prior to the previous section and the operation time of a section right before the section prior to the previous section.;COPYRIGHT KIPO 2020
