Medical and health equipment products are now diversified, mainly medium and large gram heavy magnet products, performance parameters are divided into three, the first GC-3, this brand performance intrinsic coercive force in 340-380KA/m, in sudden load play an absolute demagnetization effect; second GC-5H, remanent 402MT, intrinsic 270KA/M, this performance plays a very good role in reducing spiral noise The third GC-9B, this performance is high remanence, high intrinsic, more used in medical equipment motor, with this low current, high speed and high stability.
