Product Description:

The MAC112D-0-HD-3-C/130-A-1/S005 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive amplifier commands into precise rotary motion for positioning and velocity control in automated machinery and transfer lines. By combining a laminated stator, permanent-magnet rotor, and a closed-loop tacho circuit, the unit supplies smooth torque production for machine tools, packaging stations, and general assembly axes. Because it is intended for analog drive systems, the motor supports predictable response during repeated starts, stops, and speed changes in everyday industrial motion tasks.

Rated for a nominal speed of 1500 rpm, the motor can sustain continuous operation at that shaft velocity without exceeding thermal limits. An integrated blocking brake is supplied in the standard version, and when activated it applies up to 45 Nm to hold the load at standstill. Rotor position is monitored by an internal tacho generator that produces 3 V/1000 rpm. Heat generated in the winding is removed by natural convection, so no external blower or liquid circuit is needed. Accurate mounting is aided by a centering pilot of 130 mm, which helps align the motor with the mating machine surface.

The electrical design follows winding code HD, matching coil resistance and inductance to analog servo amplifiers in the same family. Mechanically, the frame corresponds to size 112, giving a housing diameter that fits standard MAC stator laminations. For feedback and auxiliary coupling duties, the shaft is extended on the rear and equipped with tacho feedback and a second shaft end, allowing additional mounted components without extra adapters. This rear extension can be useful where feedback devices or other coupled elements must share limited space behind the motor. Power is introduced through a keyed connector positioned on side A, which helps keep the cable run parallel to the machine bed and away from moving parts.
