Permanent Magnets
Ferrite
Ferrite magnets are more commonly referred to as ceramic magnets. They are mostly composed of strontium and Iron oxide (SrO . 6Fe2O3) and offer solid performance with their low cost, higher coercive force than alnico and low recoil permeability. They are widely used for loudspeakers, small motors, generators, and rotors.
we offers a complete line of ceramic magnets.
Characteristics
Low cost
Strong resistance to corrosion
Easy to magnetize, thus allowing magnetization after assembly
Lower energy products than alnico or rare earth magnets
Very stable when exposed to temperature or stray fields

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.
