Multi-Poles Rotor Magnet Permanent AlNiCo Six-Poles Paramenters
Size: 1.870″ Dia. x 1.250″
Number of Poles: 6

Features:
Permanent alnico magnet material
Especially effective on thin metal
6-Pole Magnetic face
Counter sunk center mounting Hole.
Alnico rotor magnets are designed with multiple poles; each pole alternates in polarity. The hole in the rotor is designed for mounting onto shafts. They are excellent for use in synchronous motors, dynamos and air turbine generators.
Features
• Alnico rotor magnets are made with Alnico 5 material and have a maximum temperature of approximately 1000°F.
• They are supplied un-magnetized unless otherwise requested. Magnetization after assembly is required to gain the full benefits of these magnets.
• SDM provide a magnetization service for assemblies incorporating these magnets. We can normally magnetize them within one working day of receipt.

SDM can supply various sizes of AlNiCo magnets, according to per customer's requests and designs. Please contact us and offer the shape, size, tolerance and grade of ALNiCO rotor magnets. If you need assistance with your requirements, please contact us.

With the best temperature resistance and the most advanced commercial magnet material, Alnico providing for excellent stability over a wide temperature range. A properly designed circuit using alnico magnets will have a stable flux output during temperature fluctuations. Although Alnico displays considerable residual induction it conversely exhibits among the lowest coercivity of any magnetic material. A consequence of low coercivity is sensitivity to demagnetizing effects caused by external magnetic fields, shock, and application temperatures. For critical applications, Alnico magnets can be magnetically stabilized to minimize these effects. Alnico magnets can be partially demagnetized if like poles of magnets are brought together. Placing individual magnets in contact with ferrous materials can also partially demagnetize them. Care must be taken in handling magnetized magnets.
