This paper details the development of a digital rotor position estimation algorithm for BLDC motors utilizing line-to-line signals. Reducing the use of external sensors reduces cost and risk of failure in the motor. Current methods use electrical circuits for Zero Crossing Point (ZCP) detection, however this implementation can be retrofitted onto existing architecture without additional hardware changes. Experimental testing is performed using the algorithm on a 3-phase, 8 pole-pair BLDC motor embedded within a Circular Force Generator (CFG) using a industry standard microcontroller. The results are compared against a more conventional Hall sensing method. The testing confirms accurate velocity tracking to within a 1 RPM error and maintain consistent power consumption. Although the algorithm is proven to be effective in a laboratory setting, additional testing on aircraft vibration cancellation hardware is recommended to validate performance when dynamic loads are applied.
