The Bosch Rexroth Indramat MAC090B-0-JD-4-C/130-B-1/WI518LV/S003 from the MAC AC Servo Motors series is a robust MAC Permanent Magnet Motor delivering a continuous torque at standstill of 6.7 Nm (peak 10.5 Nm) and a torque constant at 20 °C of 0.41 Nm/A. At a nominal speed of 3000 min-1 it draws 18.2 A continuously (peak 28.5 A), supported by a maximum pulse current of 137 Amperes. The motor’s rotor moment of inertia is 36 x 10-4 kgm2 and its thermal time constant is 60 min (45 min under special conditions). Weighing 18 kg, it features natural convection cooling, windings resistance of 0.38 Ohm and inductance of 2.0 mH at 20 °C. Rated IP65 per DIN 40 050, it resists dust and water jets, and meets IEC 721-3-3 (1987) and EN 60721-3-3 (1994) environmental classes 3M1 longitudinally and 3M6 laterally, ensuring reliable performance in harsh conditions.
