Appliance for foaming beverage or foodstuff

1. A method of foaming a liquid for consumption using an appliance comprising a container mounting portion to mount thereto a container to contain the liquid; an agitation system configured to foam the liquid, the system comprising a stator arranged external a mounted container, the stator configured to generate a rotating magnetic field for transmission of torque to rotate a rotary agitator arranged in the mounted container; and the stator comprising at a circuit board with electrically conductive portions formed thereon, wherein the electrically conductive portions are connected with at least a two phase configuration, each phase being arranged such that a face of the circuit board comprising a phase comprises a single phase only, the method comprising:

generating the rotating magnetic field by applying electrical energy to the electrically conductive portions of the stator formed on the circuit board; and

rotating the rotary agitator arranged in the container for containing the liquid by applying the torque from said field to the rotary agitator.

2. The method according to claim 1 , wherein the electrically conductive portions are arranged into active portions that each generate a magnetic pole for the rotating magnetic field.

3. The method according to claim 1 , wherein the stator comprises an additional circuit board arranged as a laminate with the circuit board.

4. The method according to claim 1 , wherein the electrically conductive portions of each phase are complimentary in shape to each other and are rotationally offset to each other.

5. The method according to claim 1 , wherein the stator extends over a portion of a base of the container.
