Multi-Poles Rotor Magnet Permanent AlNiCo Six-Poles Paramenters
Part No.  MPCOARM-6 SERIES
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
Permanent alnico 5 rotor 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.
• We provide a magnetization service for assemblies incorporating these magnets. We can normally magnetize them within one working day of receipt.

ALNICO magnets are made from aluminum, nickel, cobalt, copper and iron. Great for high heat applications. Maximum working temperature 975°-1020° F.
We can supply various sizes of AlNiCo magnets, according to the customer’s requests and designs. Please contact us and provide the shape, size, tolerance and grade of ALNiCO magnets. If you need assistance with your requirements, please contact us.

Alnico has the best temperature coefficient of any but the most advanced commercial magnet material, 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. Typical open circuit Alnico 5 applications require a long magnetic length to pole surface ratio (usually 4:1 or greater) to ensure good magnetic performance. with MPCO’ technical staff to confirm best ratio for your application. Disc Alnico Magnet for Sensor Ø20mm x 10mm
