Size: Size: 2.000″ Dia. x 1.250″
Number of Poles: 8
Permanent alnico magnet material
Especially effective on thin metal
8-Pole Magnetic face
Permanent alnico 5 rotor magnet material. Especially effective on thin metal. 8-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.
• Alnico rotor magnets are made with Alnico 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 Magnet is composed primarily of Aluminum,Nickel,Cobalt,Copper and Iron. It has very good corrosion resistence and high temperature operation. Although other materials offer greater energy and coercivity values, the high remanence and thermal stability of AlNiCo makes it the most cost effective material for certain applications, like generator, microphone lifting, voltmeters and measuring instruments. It is widely applied in high stability fields as aerospace, military, automobile, and security system.
Alnico 5, the most widely used grade, delivers energy to a magnetic circuit more economically than any of the other Alnico grades. Alnico 8 possesses the highest coercive force of all Alnico grades, as well as excellent energy per unit volume and a low reversible temperature coefficient. It is recommended for applications exposed to strong demagnetizing fields, or where space considerations dictate a short magnetic length. 8-Poles Cast Multi-Pole AlNiCo Rotor Magnet
