MAC093B-1-GS-3-C/110-A-1

The MAC093B-1-GS-3-C/110-A-1, Bosch Rexroth Indramat, MAC AC Servo Motors employs a high-performance MAC Permanent Magnet Motor design with IP65 protection for robust dust and water ingress defense. The motor integrates a standard blocking brake and a precision B encoder, enhancing position hold and feedback accuracy. A power connector on Side A streamlines installation, while the brushless construction and lifetime-lubricated bearings eliminate maintenance downtime. Factory-fitted thermoswitches continuously monitor winding temperature, safeguarding against overload and ensuring uninterrupted operation.

Engineering details include a 38 A continuous current at standstill and 14.5 Nm continuous torque at standstill, delivering strong static holding capability. Dynamic performance is defined by a 4000 RPM nominal motor speed and a 192 A maximum peak of pulse current for rapid acceleration. The motor’s 29 x 10^-4 kgm² rotor moment of inertia and 0.388 Nm/A torque constant at 20 °C yield responsive torque control, while the 2 mH winding inductance and 0.136 Ω winding resistance at 20 °C ensure predictable electrical time constants. A 50 min thermal time constant allows for accurate thermal modeling, and the 16.5 kg mass is balanced for high torque density. The fixed axial blower delivers surface cooling via 230 V AC, maintaining optimal temperatures across 0…45 °C with an 80 mm clearance requirement.

Integration into machine tools, packaging lines, or robotic cells is simplified by the compact Motor Size 93, Motor Length B envelope and IP65 housing. The combination of brushless design, lifetime-lubricated bearings, and dual thermoswitch protection ensures exceptional reliability in harsh environments. Engineers benefit from the motor’s high torque-to-inertia ratio and rapid dynamic response, making the MAC093B-1-GS-3-C/110-A-1 an ideal choice for applications demanding precision motion control and minimal maintenance.
