EMS consists of coil, electric controller and cooling water system, electric control system consists of IPC, local control cabinet and inverter cabinet.
Technical Features of KEMEIDA EMS
A new algorithm has been developed by KEMEIDA and GL electromagnetic field software Co., names AGILD EM stirring algorithm, which uses new strip magnetic field differential integral equation.
This software can design electromagnetic parameters optimized. EMS shall be with high magnetic induction and stirring force. So stirring effect shall be great.
Stirring force can be calculated by this software according to different frequency and current. So the best frequency and current can be provided for user.
Optimized design shall be done for L/D. Iron core length shall be increased properly. So stirring effect shall be improved.
Kemeida has also other software for designing F-EMS to calculate best position of F-EMS.
Kemeida EMS uses low voltage and large current, which can avoid damage of peak voltage to insulation. It shall make reduce current leakage and prolong EMS life.
Frequency arrange shall be widened to choose the best frequency.
Put EMS lower properly to make magnetic field around meniscus as little as possible to ensure strong magnetic field.
