ABSTRACT:
An apparatus for incrementally controlling actuation of an alternating current motor and rotation of the motor shaft, to incrementally control rotation of a rotatable member connectable to the motor shaft. The apparatus includes motor pulsing elements for controlling actuation of the motor and rotation of the motor shaft and rotatable member. The motor pulsing elements increase or decrease motor actuation and motor shaft and rotatable member rotation in increments of about ten percent, between about ten and one-hundred percent of full actuation and rotation, for correspondingly controlling a system controllable thereby, such as a beverage powder dispensing system in a beverage dispensing machine.
