Product Description:

The MAC112C-0-ED-1-B/130-A-0/I00625/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as a rotary actuator for analog drive systems, converting drive amplifier current into controlled torque and speed for positioning tasks on packaging, printing, and material-handling machinery. By integrating a tacho generator and feedback interface, the motor supplies real-time velocity data to the drive, enabling closed-loop regulation within industrial automation cells.

This model is built on frame size 112, and its housing aligns to machinery with a centering diameter of 130 mm. The shaft can reach a nominal speed of 3000 rpm, and winding code ED identifies the motor's electrical configuration. These values influence drive matching, coupling selection, and the expected operating range. The stator and rotor are proportioned for this housing length, giving a balanced ratio between inertia and peak torque. Axial wiring is simplified because the power conductors use a dedicated connector, which helps separate high-current lines from encoder cabling. Heat generated in the copper windings is transferred to the ambient air by the cast-iron frame, allowing the drive to sustain its rated cycle in many fan-free cabinets.

Thermal dissipation relies on natural convection, so no external blower or liquid circuit is required. Position and velocity are relayed through incremental encoder feedback, giving the analog controller a high-resolution pulse train for velocity loops. The motor uses length code C, and the armature terminals are accessed through a connector on side A that locks with a quarter-turn bayonet. A built-in tacho generator outputs 3 V/1000 rpm, which the drive uses for velocity feedback in legacy analog systems. Because a blocking brake is not present, any load-holding function must be provided by external brakes or the drive's torque-clamp features.
