Product Description:

The MAC11C-0-HD-2-C/130-A-0 W is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, the unit supplies regulated torque and speed to automated machinery such as conveyor axes, packagers, and gantry tables, linking electrical commands with mechanical movement in industrial automation. It is suited to applications that need repeatable motion but use established analog servo architectures instead of newer networked drive platforms. Power conductors are routed on side A, which can simplify cable runs when the drive is mounted in line with the motor.

Its mounting interface provides a centering diameter of 130 mm, allowing accurate alignment with gearboxes or machine frames. Under continuous standstill conditions, the motor draws a current of 41.0 A to generate a holding torque of 27.0 Nm, which supports load retention while the shaft remains stationary. During motion, the windings deliver rated rotation at 2000 rpm, while transient acceleration can be supplied by a peak pulse current of 195 A. Heat created by these operating points is removed through natural convection, so no external blower or liquid circuit is required. This cooling method reduces installation complexity because the motor does not require separate airflow hardware or coolant plumbing.

The rotor inertia of 0.0170 kg·m² balances rapid response with stable velocity regulation, and the overall motor mass of 48 kg adds structural damping on rigid machine plates. Thermal conditions rise slowly thanks to a time constant of 100 min, giving the drive additional margin before temperature-based derating occurs. Each ampere applied through the windings produces torque at a rate of 0.730 Nm/A, and this value pairs with a winding inductance of 2.5 mH and a resistance of 0.150 Ω to support predictable current-loop behavior. Tacho feedback provides a tacho voltage of 3 V per 1000 rpm, allowing analog controllers to close the speed loop without digital encoders. That analog speed signal supports conventional velocity control without extra digital feedback processing. Because the motor has no blocking brake, position retention during power-off must be handled by external mechanics.
