MAC112C-0-HD-4-C/180-A-0/WI522LV/S035

The MAC112C-0-HD-4-C/180-A-0/WI522LV/S035 from Bosch Rexroth Indramat is a high-performance member of the MAC AC Servo Motors series, designed for demanding industrial automation. This MAC Permanent Magnet Motor features a compact Motor Size of 112 and a robust Motor Length C configuration. With a Nominal motor speed of 2000 min^-1 and a mass of just 48 kg, it balances power density and installation flexibility. The unit’s Cooling Type of Natural Convection ensures efficient thermal management without auxiliary components, ideal for environments where forced cooling is impractical.

The motor delivers reliable electrical performance, boasting a Continuous current at standstill of 41 A (67 A peak) and a Maximum peak of pulse current of 195 A for high-dynamic load cycles. It generates a Continuous torque at standstill of 27.0 Nm (44.0 Nm peak) and exhibits a precise Torque constant at 20 °C of 0.730 Nm/A. The electrical design includes a Windings resistance at 20 °C of 0.150 ohm and a Windings inductance of 2.5 mH, optimizing current response and minimizing losses. A Rotor moment of inertia of 170 x 10^-4 Kgm^2 ensures smooth acceleration profiles and reduced settling times. The integrated AC Servo Motor control electronics support analog drive interfaces, facilitating straightforward integration into existing systems.

Operational robustness is achieved through a Thermal time constant of 100 min (75 min under peak load), enabling sustained operation under varying workloads and minimizing thermal degradation. The motor’s natural convection cooling eliminates the need for external fans or pumps, reducing maintenance and enhancing reliability. Incremental feedback is provided by the built-in encoder with standard mounting, offering high-resolution position and speed monitoring critical for closed-loop control. Optional tachofeedback further refines velocity regulation, ensuring precise motion control in applications with rapid acceleration and deceleration demands. The absence of a blocking brake simplifies mechanical interfacing while maintaining dynamic responsiveness.

Integration into automation platforms is simplified by the forward-mounted power connector on Side A, streamlining cabling in compact layouts. This motor seamlessly interfaces with Bosch Rexroth drives and controls, supporting advanced features such as electronic parameter recognition and adaptive tuning. Typical applications include packaging machinery, CNC positioning systems, robotic manipulators, and other precision motion tasks where high torque density, accurate feedback, and low maintenance are paramount. The MAC112C-0-HD-4-C/180-A-0/WI522LV/S035 offers engineers a versatile, high-reliability solution for modern industrial challenges.
