A cooking appliance (10) includes a housing (12), a food process area (14) inside the housing, a heat source (22, 504), a low voltage DC motor (18, 510, 610) driving an impeller (16) disposed upstream of the heat source to circulate air and convectively transfer heat for preparing food In one embodiment, the heat source (22), serving as a voltage divider, and a shunt (24), cooperate to regulate the voltage and current input for driving the low voltage DC motor (18). In another embodiment, the heat source (504, 604) is connected across an AC power source (502, 602) and a voltage divider (506, 606) regulates the voltage input to the low voltage DC motor (510, 610). |
