Neodymium magnets block L30x20x2.7mm, grade of N35SH, this magnet is special designed for an alternator, the working temperature of the magnet required higher than 120℃, normal grade like N35 or N35M and even N35H is unable to ensure the good performance. We also provide plastic insert between each 2pcs of the magnet, as the thickness is only 2.7mm and the magnet itself is brickle, we also provide N pole marked with a red line, so it can save time for our clients when they assembly the magnet onto the rotor.
