The control of a brushless dc (BLDC) motor, using bit-streams is presented. Bi-polar signals are represented using a uniformly weighted bit-stream which can be manipulated using simple digital logic to create a variety of control actions. This paper presents the functional elements required for the implementation of a proportional integral (PI) controller to affect speed and torque control on a BLDC motor. Preliminary experimental results on a standard BLDC motor using an Altera field programmable gate array (FPGA) are presented and show the viability of this technique.
