Three phase motors with current source DC-link - converter type SD   This Faurndau three phase motor with converter in digital circuit technique offers decisive advantages when used in many areas of machine industry and plant engineering in terms of smooth running, torque behavior and sturdiness.   This low-maintenance drive system, consisting of motor with squirrel-cage rotor and sturdy thyristor converter offers in a wide range of capacity a tuned unit with high performance and reliability.   Advantages of SD motors: Maximum torque in the overall regulated speed range available. Standard rated speeds between 1000 min-1 and 3000 min-1, in special cases up to 7000 min-1 Motor and generator operation of the machine. Energy regeneration into the power supply line during breaking processes Rated torque even when rotor stand still without time limit High start-up torque up to 3 x Mn with low line supply stressing possible Brushless and therefore low-maintenance Exact speed control without encoder on the machine shaft General design of the SD converter: Reliable converter system with DC DC link Externally commutated converters with thyristors, no forced commutation device or commutation equipment High peak overload capacity of the current converter Simple system control with impressed magnetic machine flow and minor current control loop Information electronics with plain text display; digital speed control circuit with inner current control loop Power range 8 kW to 400 kW Frame sizes IEC 112 to IEC 280 Enclosure Standard IP 23 S Cooling method Forced-air cooling IC 06 Download of the product catalogue as PDF file Inquiry form   Technical contact partners: Dipl.-Ing.
