All-Ferrite Magnet Design
The high and extraordinarily rapid recent rise in the price of rare earth magnets, along with their increasingly uncertain supply, has resulted in understandable reluctance of OEMs to apply conventional permanent magnet technology, which commonly rely on such material.
NovaTorque is NOT susceptible to these high costs and supply vagaries. Its unique and patented, flux-focusing, conical air gap rotor and stator geometry allows NovaTorque to achieve rare-earth magnet-like performance with low-cost, readily available, ceramic ferrite magnets.
The chart below illustrates the dramatic difference in magnet pricing.
