Plastic magnetic rotor and magnetic ring are magnets formed through injection workmanship, after mixed with magnetic powder and resin. It can be axial-direction single pole magnet, or radium- direction multi-pole magnet, or shaft and radium direction complex magnet. Neat appearance, without flaw; high precision, good constancy, no ne-ed for re-processing, stable performance and resistance shock. The shape can be complex and micro- shape. Th-ey are necessary signal source and constant magnet source. It is superior to other magnetic things. It is mainly us-ed for industrial automatic equipment, D/C motor, shaft-currency electric fan motor, transmission air condition mot-or, instrument motor ect.
