Product Description:

The MAC112A-0-VD-3-C/130-A-1/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it interfaces with legacy current-controlled amplifiers to generate precise shaft motion in material handling stations, tool changers, and other automated assemblies. By converting regulated armature current into controllable torque, the unit forms the core mechanical element that moves loads in synchronization with external command signals.

To hold positions during power-off, the unit is supplied with a standard blocking brake that develops 45 Nm of static torque, preventing axial drift on vertical axes. Accurate mounting is simplified by the 130 mm centering diameter, a clearance fit that seats the housing concentrically inside machine frames. Heat produced by copper losses is removed through natural convection, eliminating the need for forced-air ducts in compact cabinets. Under continuous duty, the rotor attains 2000 min⁻¹ at rated voltage, matching speed loops typical of mid-capacity transfer lines. Power conductors enter through a connector on side A, so cabling can exit the drive cabinet in the same direction as adjacent field wiring.

The feedback chain is built around tacho feedback and a second shaft end, allowing a mechanical encoder or belt pulley to share the rear stub while the tacho generates the velocity signal. This tacho produces 3 V/1000 min⁻¹, a level compatible with analog controllers that expect linear speed feedback at standard quality. Electromagnetic parameters follow the VD winding code, and the active cross-section corresponds to motor size 112, giving a continuous torque range appropriate for medium inertia loads. With motor length A, the stack height stays moderate, easing installation in machines where axial space is limited.
