Product Description:

The MAC11C-0-HD-2-C/130-A-0 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it generates controlled rotary motion for positioning and speed-regulated axes in automated machinery. The motor interfaces with analog drive amplifiers and supports closed-loop motion control without discrete fieldbus communication. This arrangement suits equipment that relies on current-controlled servo operation for repeatable speed and positioning tasks.

It operates at a nominal speed of 2000 rpm, which matches standard gearbox ratios and spindle demands in medium-inertia systems. Under continuous stall, the stator can supply 27.0 Nm while drawing a standstill current of 41.0 A, so the drive must sustain that load thermally. For rapid acceleration, the windings can accept a peak pulse of 195 A, allowing short bursts of torque before controller limiting intervenes. Torque is generated in proportion to current with a constant of 0.730 Nm/A, allowing load estimation from measured current. The windings have an inductance of 2.5 mH and a resistance of 0.150 Ω, and power is routed through an INS 108/06 connector that requires cables with a cross-section of 6.0 mm² to limit voltage drop. These electrical values influence current response and the voltage demanded from the amplifier during dynamic motion.

The unit weighs 48 kg and has an overall length of 460 mm from the flange to the rear housing, so mounting and support must account for its size. A centering diameter of 130 mm and a 32 mm keyed shaft establish the mounting interface, while the rotor inertia of 170 × 10⁻⁴ kg·m² affects servo tuning by resisting changes in speed. Cooling is provided by natural convection, so airflow around the frame should remain unobstructed during operation. The thermal time constant is 100 min, which gives the motor a measured delay before winding temperature rises during load transients.
