The MAC093A-0-PS-4-C/110-R-1/WI522LX from Bosch Rexroth Indramat delivers 9.2 Nm continuous torque and features 0.659 Ohm winding resistance. Part of the MAC AC Servo Motors, it operates at a nominal speed of 3000 RPM and handles peak currents up to 76 A. This synchronous servo motor offers a rotor moment of inertia of 22 x 10-4 kgm2 and axial cooling for rapid heat dissipation.
It includes an electrically actuated holding brake releasing in 30 ms and sustains a thermal time constant of 50 min. Continuous current at standstill reaches 15 A. Windings inductance is 8.0 mH, ensuring responsive performance.
