Product Description:

The MAC112C-0-ED-4-C/130-A-2/MR121/S018 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is a motor for analog drives. It generates controlled torque and speed in automated machine axes, material-handling equipment, and other motion tasks where closed-loop regulation is handled by an analog controller. This arrangement lets the external drive regulate position and speed through analog command signals during normal operation.

This model includes a heavy-duty blocking brake that can hold up to 60 Nm at standstill, preventing axis drift during power-off or vertical loading. Heat produced by the stator is removed through natural convection, so no auxiliary fan or liquid circuit is required. Under rated excitation, it reaches a nominal speed of 3000 rpm, matching the operating range of typical analog servo amplifiers. Tacho feedback is supplied at 3 V/1000 rpm, and the standard-quality tacho provides proportional voltage for velocity loops or redundant monitoring alongside an incremental or absolute encoder. Installation is aided by a 130 mm centering diameter that aligns the flange precisely with planetary gearboxes or machine frames.

The power leads are terminated through a connector on side A, simplifying cabinet routing when the motor is mounted with the shaft facing forward. Electrical characteristics follow winding code ED, which corresponds to resistance and inductance values used with the matching drive family for this frame. Mechanical dimensions correspond to size 112, giving a shaft height and bolt pattern consistent with other motors in the series, while the medium-length stator designated by code C balances continuous torque capability with moderate rotor inertia. This connector placement also helps keep the power connection accessible in compact machine layouts.
