Abstract
A permanent magnet air heater has a housing with an internal chamber accommodating an electric motor rotating a fan to move air through the housing. A non-ferrous member having bores for cylindrical magnets and a steel member with a copper plate secured to the steel member are rotated relative to each other by the motor whereby the magnetic field between the magnets and copper plate generates heat which is transferred to air in the housing moving through the housing by the fan.
Claims16
An apparatus for heating air comprising:
- a housing having an internal chamber, an air inlet opening and an air exit opening,
- a motor located within the internal chamber,
- a fan drivably connected to the motor operable to draw air into the air inlet opening, move air through the internal chamber and discharge air out of the air exit opening;
- a ferrous metal member located in the internal chamber,
- a copper member secured to the ferrous metal member,
- a non-ferrous member located in the internal chamber adjacent the copper member,
- a plurality of permanent magnets mounted on the non-ferrous member, adjacent magnets having opposite north and south polarities, and
- a drive operable by the motor to rotate the ferrous metal member and copper member and the plurality of permanent magnets relative to each other to generate a magnet force field thereby heating air in the internal chamber, said heated air being moved through the internal chamber by the fan and discharged through the air exit opening.
