MAC112C-0-HD-3-C/130-B-1/S021

The Bosch Rexroth Indramat MAC112C-0-HD-3-C/130-B-1/S021 from the MAC AC Servo Motors series is a robust MAC Permanent Magnet Motor featuring a Continuous current at standstill of 41 A and a Continuous torque at standstill of 27.0 Nm for precise load-holding applications. Capable of a Maximum peak of pulse current of 195 A, the drive sustains demanding dynamic loads and short-term torque peaks without derating. The motor spins at a Nominal motor speed of 2000 min^-1 and delivers a Torque constant at 20 °C of 0.730 Nm/A, ensuring exact current-to-torque conversion for high-resolution motion control. With a substantial Rotor moment of inertia of 170 x 10^-4 Kgm^2 and a Windings inductance of 2.5 mH alongside a Windings resistance at 20 °C of 0.150 ohm, the unit offers stable electrical characteristics across a wide speed range.

The MAC112C-0-HD-3-C/130-B-1/S021 incorporates a B-side power connection on Side B, facilitating streamlined cable management in space-constrained installations. Equipped with a C encoder for high-fidelity feedback and a Standard blocking brake providing 45 Nm of holding torque, the design ensures positional integrity during power interruptions. A Thermal time constant of 100 min and a Cooling type Natural Convection scheme maintain thermal equilibrium under prolonged standstill and cyclic duty. These integrated safety and feedback systems make the motor ideally suited for elevators, cranes, and robotic load-holding duties.

Weighing 48 kg and featuring a Motor Size of 112 with a Motor Length of C, this MAC motor balances mass and form factor for cabinet integration and retrofit scenarios. As an AC Servo Motor designed by Bosch Rexroth Indramat, it combines flexible connectivity and reliable braking to maximize uptime and streamline maintenance.
