MAC112C-0-ED-3-C/130-A-2/S030

The Bosch Rexroth Indramat MAC112C-0-ED-3-C/130-A-2/S030 AC servo motor in the MAC AC Servo Motors series offers a robust permanent magnet design tailored for demanding automation tasks. Featuring dual winding sets and a side-A power connector, this unit delivers high dynamic response and precise control. The integrated blocking brake on the second shaft end provides fail-safe holding at standstill without external intervention. With full IP65 protection for its connections and second shaft end, the MAC112C-0-ED-3-C/130-A-2/S030 is engineered for reliability in harsh industrial environments. This model includes a C-type encoder and tachogenerator feedback for enhanced position and speed monitoring.

Detailed technical specifications define its core performance: the motor achieves a Continuous Standstill Current of 57 A and generates a Continuous Standstill Torque of 24 Nm at zero speed. Peak dynamics are supported by a Maximum Pulse Current of 312 A while maintaining a Moment of Inertia of Rotor of 170 x 10^-4 kgm^2. Its nominal rotational speed of 3000 min-1 is matched to a torque constant of 0.47 Nm/A at 20°C and winding inductance of 1 mH. The copper windings present a Resistance of 0.06 Ω at 20°C, and the thermal time constant is rated at 100 Minutes. The bare motor mass of 48 kg reflects a compact yet rugged construction, with a motor length classified as C and size 112. Cooling is achieved through Natural Convection without auxiliary hardware.

Operational features emphasize ease of integration and reliable performance under variable conditions. The blocking brake uses a magnetic armature disc at zero current for immediate shaft lockout, controllable via hardware switch or PLC interface. Dual feedback channels—encoder and tachogenerator—permit closed-loop control with selectable output direction on the angle feedback connector. Thermo switches embedded in the stator housing protect against thermal overload, ensuring safe operation through self-regulating temperature monitoring. The permanent magnet architecture provides a high power-to-weight ratio and brushless operation, reducing maintenance requirements and extending service life.

System integration is simplified by the standard flange with through-holes and universal power cable compatibility in both inch and metric diameters. The unit must be grounded to the drive amplifier and stored in a clean, dry environment to maintain its IP65 protection integrity. The MAC112C-0-ED-3-C/130-A-2/S030 interfaces seamlessly with PLCs and servo drives for synchronized multi-axis motion control. Target applications include packaging machinery, CNC equipment, and robotic assemblies where precise torque, rapid response, and environmental resilience are critical.
