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.
Claims10
An apparatus for incrementally controlling the actuation of an alternating current motor and the rotation of the motor shaft, to incrementally control the rotation of a rotatable element connectable to the motor shaft, so as to incrementally increase or decrease the rotation of the rotatable element, comprising:
- (a) an alternating current motor, including a motor shaft to which the rotatable element is connectable;
- and
- (b) means for incrementally controlling the actuation of the motor and the rotation of the motor shaft, and for incrementally controlling the rotation of the rotatable element connected to the motor shaft, to incrementally increase or decrease the rotation of the rotatable element, comprising means for processing the rotation of the motor shaft over time, which comprise a microprocessor, and means for switching the rotation of the motor shaft on and off responsive to the microprocessor, such that the motor shaft rotates incrementally responsive thereto, wherein the switching means are connected to the motor, and the microprocessor is connected to the switching means for control thereof, and means for actuating the microprocessor, connected to the microprocessor, such that actuation of the actuating means in a preset sequence provides programmed instructions to the microprocessor responsive thereto for controlling the switching means and for incrementally rotating the motor shaft responsive thereto.
A method of incrementally controlling the actuation of an alternating current motor and the rotation of the motor shaft, to incrementally control the rotation of a rotatable element connected to the motor shaft, so as to incrementally increase or decrease the rotation of the rotatable element, comprising:
- (a) activating an apparatus which includes an alternating current motor including a motor shaft to which the rotatable element is connectable, and means for incrementally controlling the actuation of the motor and the rotation of the motor shaft, and for incrementally controlling the rotation of the rotatable element connected to the motor shaft, to incrementally increase or decrease the rotation of the rotatable element, comprising means for processing the rotation of the motor shaft over time, which comprise a microprocessor, and means for switching the rotation of the motor shaft on and off responsive to the microprocessor, such that the motor shaft rotates incrementally responsive thereto, wherein the switching means are connected to the motor, and the microprocessor is connected to the switching means for control thereof, and means for actuating the microprocessor, connected to the microprocessor, such that actuation of the actuating means in a preset sequence provides programmed instructions to the microprocessor responsive thereto for controlling the switching means and for incrementally rotating the motor shaft responsive thereto;
- and
- (b) activating the actuating means in a preset sequence to provide programmed instructions to the microprocessor for controlling the switching means to incrementally control the rotation of the rotatable element connected to the motor shaft, so as to incrementally increase or decrease the rotation of the rotatable element.
