Abstract:
1. A machine that at least one of blends liquids and shaves ice, the machine comprising: a motor that operates an impeller for one of blending liquid and shaving ice; and a control system that controls the motor, the control system configured to be connected to a mains power line and to receive inputs from a switch interface, the control system including an integrated power factor correction circuit which receives input power from the mains power line, the integrated power factor correction circuit reducing noise transmitted to the mains power line and providing a boosted, regulated output voltage for use with the control system, and a drive circuit connected to the motor, the drive circuit using the regulated output voltage in order to control an effective voltage applied to the motor based on the inputs from the switch interface substantially independent of the voltage and frequency of the input power.
