Performance analysis of BLDC motor drive by varying the sensor angle for no load condition

This BLDC motor is in high demand nowadays due to its high efficiency and other significant features. As there is no use of brushes, this type of motor is having many advantages like high torque to inertia ratio, high speed, and power density and low cost compared to conventional brushed motors. To achieve more improved motor, it is important to analyse the BLDC motor's performance by varying different types of motor parameters. One of the important parameters is the sensor position or the sensor angle at which the sensor will be placed with the axis of the motor. Sensors sens the rotor position of the motor and send this information to the controller and accordingly, the switching sequence of Inverter is being decided. In this paper how varying the sensor position angle effects on the overall performance of BLDC motor in its no-load condition will be discussed.
