Drives efficiency calculator

The IEC 61800-9-2 standard requires operating point (90% Speed, 100% Torque) drive losses be 25% less than the reference drive (RCDM) or better. The Drives Efficiency Calculator will calculate power losses for your Allen Bradley drive, ensuring it meets the IEC 61800-9-2 standard.
