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.
Claims54
A heater comprising:
- an absorber plate proximate to a ferrous member;
- a plurality of permanent magnets mounted on a non-ferrous member that is adjacent to the absorber plate,
- wherein each magnet is adjacent to a magnet of opposite polarity, and
- wherein at least one magnet is adjacent to another magnet of the same polarity;
- a first drive operable by a first motor to rotate the non-ferrous member, including the permanent magnets, relative to the ferrous member to generate a magnetic field, thereby generating heat;
- and
- a plurality of fins that transfer heat away from the ferrous member.

A heater comprising:
- an absorber plate proximate to a ferrous member;
- a plurality of permanent magnets mounted on a non-ferrous member that is adjacent to the absorber plate, wherein each magnet is adjacent to a magnet of opposite polarity;
- a first drive operable by a first motor to rotate the ferrous member and absorber plate relative to the non-ferrous member, including the plurality of magnets to generate a magnetic field, thereby generating heat;
- and
- a plurality of fins that transfer heat away from the ferrous member.
2 more elements
A heater comprising:
- a rotor including a plurality of fins, an absorber plate, and ferrous plate configured to rotate within a heating housing that has an inlet for receiving fluid and an outlet for discharging fluid, wherein fluid is discharged through the outlet by the rotation of the plurality of fins;
- a plurality of permanent magnets mounted on a non-ferrous member, each magnet is adjacent to a magnet of opposite polarity;
- and
- a motor operable to rotate a drive that rotates the rotor within the heating housing to generate a magnetic field, thereby generating heat that heats the fluid within the heating housing.

A heater comprising:
- absorber tubing proximate to a ferrous member;
- a plurality of permanent magnets mounted on a non-ferrous member that is adjacent to the absorber tubing, wherein each magnet is adjacent to a magnet of opposite polarity;
- and
- a drive operable by a motor to rotate the non-ferrous member, including the permanent magnets, relative to the ferrous member to generate a magnetic field, thereby generating heat, wherein fluid flows through the absorber tubing and is heated as the fluid flows through the absorber tubing.
1 more element
A heater comprising:
- a copper tank;
- a ferrous member proximate to and touching one side of the copper tank;
- a plurality of permanent magnets mounted on a non-ferrous member that is adjacent to the one side of the copper tank, wherein each magnet is adjacent to a magnet of opposite polarity;
- and
- a drive operable by a motor to rotate the non-ferrous member, including the permanent magnets, relative to the ferrous member to generate a magnetic field, thereby generating heat in the copper tank.
