Products Overview

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.

Rotor Magnets  Specifications

Dimensions are in inches. Pull figures are maximum values; these will be achieved with a smooth steel of adequate thickness where contact faces are intimate and clean. Other sizes and shapes are available. Contact us at 800-763-4795 if you don't see what you're looking for in this brief listing.
