Supply chain stability Ferrite magnets are not subject to big price instability and potential future supply shortage of rare earth magnets.
Environmentally friendly & sustainable Ferrite magnets are mad from iron oxide and strontium which are abundant materials. Rare earth mining is more demanding and heavy on the enviorment.
Stable performance at high temperatures Ferrite magnets are more resistant to demagnetization at high temperatures.
Higher efficiency in high-frequency applications Lower conductivity of ferrite magnets reduces eddy current losses, improving motor efficiency in high-frequency applications.
