In this article, a sensorless speed control technique for brushless DC motor (BLDC) drives by estimating speed from the hall sensor signals is proposed by measuring the frequency of the in-built-hall sensor signals.Abstract:
This paper proposes a sensorless speed control technique for Brushless DC Motor (BLDC) drives by estimating speed from the hall sensor signals. Conventionally, the speed is measured using precision speed encoders. Since these encoders cost almost half of the entire drive system, there arises the need for a low cost speed estimation technique. This is proposed by measuring the frequency of the in-built-hall sensor signals. Here, a closed loop speed control of BLDC motor is proposed using a current controlled pulse width modulation (PWM) technique. Since BLDC motor is an electronically commutated machine, the commutation period is determined by a switching table that shows the hall signals' status. The entire system was simulated in MATLAB/Simulink and the performance of the system was analyzed for different speed and torque references.read more

Taehyung Kim,Mehrdad Ehsani +1 more
Abstract: This work presents the theory and implementation of a novel sensorless control technique for the brushless DC (BLDC) motor. The proposed new sensorless drive method solves the problem of the sensorless BLDC motor drives at very low speeds. It provides a highly accurate and robust sensorless operation from near zero to high speeds. For this purpose, an approach, a new flux linkage function is defined, that is speed-independent. The validity of the proposed method is verified through both simulation and experimental results and discussion.
