Brushless Direct Current (BLDC) Motors are
gaining rapid popularity and are used in many applications. One
such application is automobiles where the BLDC motors are used
to run the electric vehicles such as e-bikes and e-cars. For
commutating a BLDC Motor, Trapezoidal Algorithm is used
ubiquitously. But Trapezoidal Algorithm has limitations such as
utilizing the motor’s efficiency to the maximum. In theory, it is
known that the sinusoidal and FOC algorithms can overcome the
limitations of Trapezoidal commutation. In order to implement
sinusoidal and FOC algorithms, the exact position (angle) is
needed. In this paper, measurement of the position (angle)
information along with a new sensor drive scheme of BLDC
Motor for commutation using Magnetic Rotary Encoder
