Magnets for Motor Assemblies
Samarium Cobalt (SmCo) magnets are often used due to the tolerance for high temperatures and magnetic strength.
- Samarium Cobalt and Neodymium rare earth magnets are commonly used
- Ferrite or ceramic magnets are available and are less expensive
Custom Magnets for Motor Assemblies
In motors, Samarium Cobalt (SmCo) magnets are often used due to the tolerance for high temperatures and magnetic strength. The maximum temperatures for SmCo magnets are between 250 and 550 °C. SmCo are also corrosion resistant, while the Neodymium counterparts are not, therefore surface coatings are not necessary for most applications. This allows for broader use in medical applications. Neodymium magnets are typically used in electric car motor applications. Ferrite, or ceramic, magnets are not as strong as rare earth magnets but have a strong resistance to demagnetization and corrosion. This makes ferrite magnets a more affordable choice for use in most types of electric motors. The maximum operating temperature is 250°C.
