Development of BLDC Motor Controller using Sensor-Based Method

In this paper, the development of a Speed Controller of a Brushless DC motor using a Hall Effect position sensor has been illustrated. Implementation of a system that can control the motor's speed in four different modes: motoring, coasting, braking, and regenerative braking as well as the development of algorithms and control strategies that enable smooth transitions between the four modes of operation. The primary focus of using the Hall Effect position sensor is to determine the rotor position of the BLDC motor and generate Pulse width modulation (PWM) signal using the rotor position. The sensor-based control method results in improving performance and efficiency as it provides more precise control over the motor's speed, position, and torque and reduces motor noise and vibrations by providing smoother operation and reducing the likelihood of torque ripple.
