Servo Motor Sizing: brushless ac pm
IEC132 02 to IEC80 02
Servo motor sizing data for brushless AC permanent-magnet, hybrid stepper-servo, and direct-drive torque motors across NEMA 17/23/34/42 and IEC 42–310 mm frame sizes. Fields include continuous and peak torque, rated/max speed, rotor inertia, torque constant (Kt), back-EMF constant (Ke), winding resistance, thermal time constant, encoder resolution, weight, shaft diameter, voltage class, and IP rating. Based on Yaskawa Sigma-7/SGMCS, Siemens 1FK7/1FL6, Beckhoff AM8000/AM887x, Kollmorgen AKM/KBM/TB, Allen-Bradley Kinetix MPL, Applied Motion STM, Leadshine ELS, NEMA MG-1 Part 30, IEC 60034-1.
