  •  Description: 

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 Ni-Cu-Sn to make protection.
