Product Description:

The MAC112C-0-ED-3-C/130-B-1/S005 is a servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, the unit accepts command voltages and produces corresponding torque. It also delivers position or speed feedback for closed-loop control in automated machinery such as gantry axes, tool spindles, and pick-and-place heads. In this role, the motor works with an external drive that regulates current to the windings in response to the commanded motion.

This model runs at a nominal speed of 3000 rpm, allowing it to suit applications that require steady servo operation over a common speed range. A centering diameter of 130 mm provides accurate piloting on mounting flanges so that shaft misalignment is minimized during installation. Heat is removed through natural convection, eliminating the need for forced air or liquid circuits and simplifying the surrounding layout. Because the cooling method is passive, no separate fan wiring or coolant plumbing is required at the motor. The integrated blocking brake supplies 45 Nm of static holding torque, keeping vertical or load-bearing axes motionless when power is off. For velocity feedback, the tacho generator develops 3 V/1000 rpm, a signal level suited to analog speed regulators that rely on proportional voltage input.

A frame size of 112 establishes the stator diameter and magnetic cross-section, while motor length code C extends the active iron for higher continuous power without changing the footprint. Electromagnetic properties are set by winding code ED, matching phase resistance and inductance to drives that deliver the required current. The power terminals are grouped on side B, which shortens cable runs in right-hand-mounted cabinets and keeps the power connection area concentrated on one side of the motor. The motor also includes a second shaft end for auxiliary transducers, allowing additional mechanical feedback devices to be connected when required by the machine layout.
