The complete Mezomatik K DC servo drive, which includes DC servo motors with excitation from permanent magnets of the HG series and a Formic thyristor electric drive, were developed by MEZ Brno for use as part of electric drives for feed drives of metalworking machines.
For a long time, the MEZ Brno HG series electric motors have been used by leading European engineering companies Maho, Mikron, Schaublin, Skoda, TOS Kurim, Heid, Elb Schliff, Olivetti Horizon, DMG, Kolb, Waldrich Coburg, Forest Line, Gildemeister, Max Muller, Reishauer, Wotan. The lack of such a high-quality solution for domestic manufacturers in the field of servo-electric drives has affected the fact that most domestic machine tool factories also used HG servomotors and Formic servos, they were used on their machines by the Ivanovo Machine Tool Plant, Sterlitamak Machine Tool Plant, Ryazan Machine Tool Plant, Kirov Machine Tool Plant…
