High specific energy rare earth magnets are particularly suitable for the magnetic circuit miniaturization. Their low temperature coefficient, the lowest after that of Alnico magnets, makes them suitable for applications where good heat resistance, high induction and small dimensions are needed at the same time. The operating temperature can reach 350° in continuous service (consult our technical department). |
