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 – Alnico is hard and brittle, and prone to chipping and cracking. Special machining techniques must be used to machine this material. Alnico magnets require magnetizing fields of about 3 kOe (kilo Oersted). Because of their relatively low coercivities, special care should be taken to assure that alnico magnets are not subjected to adverse repelling fields, since these could partially demagnetize the magnets. Magnetized magnets should be stored with “keepers” to reduce the possibility of partial demagnetization. If alnico magnets are partially demagnetized, they may be easily re-magnetized. Multi-Pole AlNiCo Magnet Assemblies for Rotor, Multi-Poles Magnets AlNiCo Rotor Assemblies

Alnico Magnetic Characteristics-english

Alnico rotor with protected steel sleeve and potted with epoxy.
Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. Among all the available magnetic materials, they have high magnetic flux density, resistance to corrosion and excellent temperature stability, the maximum working temperature up to 600℃. Alnico magnet is widely used in all kinds of sensors and meters, electronics, instruments, medical instruments, teaching, automobile, aviation, martial and other applications.

Cast Alnico can be made into intricate and complex shapes, which is not possible with other magnetic materials.
Cast alnico magnets are manufactured by pouring a molten metal alloy into a mold and then processing it through various heat-treat cycles. The resulting magnet has a dark gray appearance and may have a rough surface. Machined surfaces have a shiny appearance similar to steel. Cast magnets may be manufactured in complex shapes such as horseshoes, which is not possible with other magnet materials.

Types of Cast Alnico

Cast Alnico 5 — This is the most commonly used. This alnico material is used extensively in rotating machinery, meters, instruments, sensing devices, and holding applications, to name a few. For best results with alnico 5 magnets, the length should be no less than 5 times the cross-section diameter; or 5 times the diameter of a circle equal in area to the cross section.
Cast Alnico 8 — This magnet has the highest temperature stability of any commercially available magnetic material. Improved crystal structure and alloying techniques achieve a 6.0 energy product and high resistance to demagnetization. Typical uses include computer keyboards, drives, printers, microphones, meters, motors, generators, relays, reed-switch relays, and transducers.
