After 17 years, our furnace is wearing out. Earlier this week, the blower finally seized up, so we decided to bite the bullet and shop for a new furnace. Our house requires an 80-90,000 BTU furnace.
A feature in the generator mode in parallel to the grid is that the rotor speed is higher than in the driving mode. Then active energy is being given to the grid. [ 1 ] Another disadvantage of induction motor generator is that it consumes a significant magnetizing current I 0 = (20-35)%.
An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. [ 1 ] [ 2 ] [ 3 ] Induction furnace capacities range from less than one kilogram to one hundred tons, and are used to melt iron and steel , copper , aluminum , and precious metals .
It is also known as a unipolar generator, acyclic generator, disk dynamo, or Faraday disc. The voltage is typically low, on the order of a few volts in the case of small demonstration models, but large research generators can produce hundreds of volts, and some systems have multiple generators in series to produce an even larger voltage.

A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity.An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.
The typical efficiency of TEGs is around 5–8%, although it can be higher. Older devices used bimetallic junctions and were bulky. More recent devices use highly doped semiconductors made from bismuth telluride (Bi 2 Te 3), lead telluride (PbTe), [10] calcium manganese oxide (Ca 2 Mn 3 O 8), [11] [12] or combinations thereof, [13] depending on application temperature.
The whole assembly is then mounted in a frame containing the motor stator and generator stator. The whole construction is mounted in a cubicle which features a heat exchanger and water cooling systems as required. The motor-generator became the mainstay of medium frequency power generation until the advent of solid state technology in the early ...
