Company Profile

Corrosion Resistant Neodymium Motor Magnet N42H Ndfeb Magnetic Materials

Magnetic Materials Ndfeb Magnet N42H Neodymium Arc Magnet For Motor

Wind turbines are subject to alternating temperatures due to long-term exposure to the outside world; At the same time, motor loss also leads to motor temperature rise. Ferromagnetism will change to paramagnetism (310 ℃) because the temperature exceeds the Curie point. When the temperature rises, the coercivity of NdFeB Magnets will decrease. Therefore, when selecting NdFeB Magnets, appropriate coercivity should be selected to avoid loss of excitation.

Because the magnetic poles of the rotor need to be consistent, the requirements for magnetic steel also need to be consistent, including dimensional tolerances and magnetic properties.

Neodymium iron boron alloy contains active rare earth elements, which are easy to oxidize and rust. Therefore, in practical applications, it is necessary to carry out surface anti-corrosion treatment on neodymium iron boron. Common coatings include electroplating nickel, zinc, and electrophoretic epoxy resin.
