Abstract: An induction heating system is provided. The induction heating system includes an induction coil configured to generate a magnetic field and a heating target spaced apart from the induction coil. The heating target is moveable to create a varying distance between the induction coil and the heating target along a length of the heating target to generate a varying amount of heating of the heating target, along the length of the heating target, by penetration of the heating target by the magnetic field generated by the induction coil.

Abstract: A heating system is provided. The heating system comprises an induction heating assembly configured to generate a varying magnetic field and a heating target assembly comprising one or more heating targets, wherein the one or more heating targets are moveable relative to the induction heating assembly, the one or more heating targets being heatable by penetration with the varying magnetic field.

Abstract: A hair styling device for heating hair is provided. The device comprises an induction heating plate arranged to be heated by penetration with a varying magnetic field and an induction heating assembly configured to generate the varying magnetic field.

Abstract: A heating system is provided. The heating system comprises an induction heating assembly configured to generate varying magnetic fields, a heating target assembly comprising a plurality of heating targets, the plurality of heating targets being heatable by penetration with a varying magnetic field. A first subset of the plurality of heating targets has a first resonant heating characteristic and a second subset of the plurality of heating targets has a second resonant heating characteristic, and the first and second resonant heating characteristics are different. The system further comprises a controller configured to: control the induction heating assembly based on the first resonant heating characteristic to generate a first varying magnetic field to heat the first subset and control the induction heating assembly based on the second resonant heating characteristic to generate a second varying magnetic field to heat the second subset.

Abstract: An electric motor is provided that includes a rotor, a stator, and a filter. The stator includes a stator core and windings. The filter is a magnetic low-pass filter including a coil having one or more turns and one or more capacitors connected in series with the coil. Excitation of the windings generates stator flux, the coil is linked to the stator flux, and the filter attenuates harmonics in the stator flux.
