  The Arc magnet mainly have straight arc ,oblique arc and bread arc. This bread arc magnet is widely used in a series of elevator motors. The precision of magnet dimension tolerance and the consistency of property is very critical elements for motor applications. Meanwhile, in order to enhance rust-resisiting ability of magnet coating, we take Black Epoxy  to make protection.
