MAC112B-0-GD-3-C/180-A-0/S012

The Bosch Rexroth Indramat MAC112B-0-GD-3-C/180-A-0/S012 from the MAC AC Servo Motors series is an AC Servo Motor of size 112 designed for high-precision automation tasks with a compact length B housing. With a mass of 36 kg and a robust winding GD configuration, this servo motor delivers exceptional mechanical stiffness and stability for dynamic motion control applications across small to medium frame sizes. Its advanced permanent magnet design ensures consistent torque output across varying load conditions while maintaining a low profile and high power density for space-constrained installations. The size 112 architecture offers a balanced compromise between torque capacity and installation footprint, catering to various production-line configurations.

At standstill, the unit produces a continuous torque at standstill of 10.7 (13.0) 5) Nm while drawing a continuous current at standstill of 14.5 (17.2) 5) A, ensuring immediate torque delivery for load-critical processes. The drive electronics support a maximum peak of pulse current up to 136 A for short-duration high-torque demands, facilitating rapid acceleration and deceleration profiles. Matched to the motor’s footprint, the rotor spins up to a nominal speed of 3000 min-1 with minimal frictional losses thanks to a low moment of inertia of 61 x 10-4 kgm2, enhancing responsiveness and positional accuracy. These characteristics enable the system to handle rapid cycle times with precision repeatability under varying operational scenarios.

The winding exhibits an inductance of 1.9 mH at 20 °C, optimizing current-to-torque conversion while limiting electrical noise in sensitive control loops. Equipped with a natural convection Cooling Type mechanism, the MAC Permanent Magnet Motor maintains thermal stability during extended operation without the need for auxiliary cooling devices. Altogether, the MAC112B-0-GD-3-C/180-A-0/S012 combines high dynamic efficiency and rugged durability for demanding industrial automation environments.
