Abstract
Today, brushless DC motors (BLDCM) have been used in many applications replacing to brushed DC motors. Compared to brushed DC motors, BLDCM offer improved reliability, longer life, smaller size, and lower weight. Besides, BLDCM have become more popular in applications where efficiency is a critical concern and, generally speaking, a BLDCM is considered to be a high-performance motor capable of providing large amounts of torque over a wide speed range. In this paper, a research on sensorless control method which can drive a BLDCM smoothly from standstill to high speeds without position or speed sensors is carried out. Initial rotor position as well as speed of motor at a low speed range is estimated based on the inductance variation principle while at higher speed, the back EMF technique is applied. This sensorless control algorithm is modeled and simulated with MATLAB/SIMULINK software to verify the abilities of the method. The drive control scheme has been implemented on a single-chip controller (STM32F103) and experimental results reveal that the control procedure can work smoothly.
