Product Description:

The MAC112D-0-HD-3-C/130-B-1 is an AC servo motor produced by Bosch Rexroth Indramat and listed in the MAC AC Servo Motors series. Classified as a motor for analog drives, the unit converts command voltages from legacy drive controllers into controlled rotational motion for positioning and speed regulation tasks on assembly lines, packaging stations, and other automated machinery. Its operating style suits systems that rely on continuous analog reference signals rather than fully digital motion networks. This makes the motor suitable for retrofit applications and for equipment that uses established closed-loop speed control methods.

Mechanical integration is aided by a centering diameter of 130 mm, allowing the flange to seat precisely against standardized mounting faces. A built-in standard blocking brake delivers a holding torque of 45 Nm, which helps prevent shaft movement when the drive is disabled and helps keep vertical axes from drifting. At continuous load, the rotor reaches its nominal speed of 1500 rpm, a value matched to analog speed command ranges in legacy control loops. Heat generated by copper and iron losses is dissipated through natural convection, so additional fans or liquid circuits are unnecessary. The three-phase power leads exit through a connector on side B, which can simplify cable routing when the motor back face is not accessible.

The motor does not use a resolver. Instead, it integrates tacho feedback and a second shaft end, allowing closed-loop speed measurement and the attachment of external encoders or mechanical loads. The tachogenerator produces 3 V/1000 rpm, giving analog controllers a linear feedback signal that aligns with the base speed range. Electromagnetic performance is set by the HD winding code together with motor size 112 and length class D, which determine the stator layout, resistance, and thermal capacity. Tacho quality and brake performance are standard, which supports consistent operation across identical units used on multi-axis machines.
