Multipolar SmCo Ring Magnets

Features:
1) Patent No.: 90 2 23958.9
2) Sintered SmCo multipolar ring magnet parts
3) Commonly used with permanent magnet DC motors and permanent magnet
3 phase AC synchronous servo motors
4) Advantages:
a) Much smaller than that of tile magnet parts
b) Max working temperature: up to 250°C
c) A good substitute for bonded ring magnet parts with much higher BH (max)
and lower cost
d) Bound to help greatly enhancing the power of permanent magnet 3 phase
AC synchronous servo motors or DC motors
e) The cost is only one third of Japanese ones because of our unique processing
