Abstract:
1. A system that facilitates control of motor speed, comprising: a motor that is utilized to drive a load; and an optimized control component that controls respective switching to a particular state of at least two switch components associated with the motor based in part on predefined optimization criteria, wherein the optimized control component controls at least one of timing of switching the at least two switch components to respective particular states or an amount of capacitance associated with the motor; wherein the at least two switch components comprise: an auxiliary switch component that is associated with an auxiliary winding of the motor and is switched on at a specified time during a cycle of the motor, and a main switch component that connects a main winding of the motor to the auxiliary switch component, wherein the main switch component is switched on at a predetermined period of time after the auxiliary switch is turned on, based in part on the predefined optimization criteria and to facilitate reducing power loss in the motor.
