Torque ripples in BLDC motor can be eliminated to a great extend by implementing sinusoidal commutation.The paper presents a Low-cost Sinusoidal Commutation drive for BLDC motor actuator for 3rd stage of the PSLV. The method implemented as part of paper uses Linear Hall Sensors to sense the magnetic field intensity and thereby use this information to generate the gating signals .The technique of implementation proposed in [1] is used to drive the BLDC motor in this paper. This method has the advantage of being simple and implementation flexibility . Also the use of Linear Hall Sensors in driving sinusoidally commutated BLDC motors is proposed in [2] . This work uses the information from the Linear Hall Sensors to get the information about the rotor position in conjugation with proposed technique in [2] to drive the sinusoidally commutated BLDC motor actuator system . The simulation of mentioned work is realized in MATLAB SIMULINK .The implementation of proposed method is done using analog control circuits.
