Lenze Three-phase AC motors series MD fully optimized and configured to work with the frequency converter as efficiently as possible, 4-pole winding. Wide range of speed settings without field attenuation in a minimum ratio of 1:17.4 while maintaining constant torque. The design of the motors is made according to IEC 60072-1, DIN EN 50347 standards, which provides great opportunities for universal use and connection without adaptive devices. Feedback via resolvers, incremental and absolute encoders, modifications with integrated braking system.
The engines are well protected from the negative conditions of the working area, namely from the penetration of dust and splashes or water jets into the body, corrosion from the influence of aggressive media. Thermal sensors are installed for constant monitoring of temperature factors.
The energy efficiency class of this series corresponds to the class IE1 (standard).
