Three Kinds of Arc Magnets for Micromotors

There are three types of arc magnets for micromotors:
1. Samarium cobalt is resistant to high temperature (400 ℃), the metal color is bright, and the value is high. Comprehensive research shows that micromotors rarely use samarium cobalt magnets.

2.Permanent magnet ferrite, because the high temperature is superior to NdFeB in this regard is beyond doubt, to achieve unique micro-motor matching, the process cost of ferrite is high, and the rejection rate is also high, because simple fracture may is the wear angle

3. The permanent arc magnet motor with neodymium magnet as rotor magnet is small in size, light in weight, high in inertia ratio, fast in response speed of servo system, high in power and speed/component ratio, large in starting torque, and saves electricity. Motor magnets are mostly tile, ring or trapezoid, which can be used in different motors, such as permanent magnet motors, AC motors, DC motors, linear motors, brushless motors, etc.
