Product Description:

The MAC112C-0-ED-3-C/180-A-2/S029 is an AC servo motor built by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. The unit belongs to the 112-frame class and is configured for analog drive systems that need fast acceleration, accurate speed holding, and secure load retention. Within industrial automation cells, it converts commanded current into rotational motion, and its factory-installed heavy-duty blocking brake maintains shaft position during power-off or emergency stops.

The motor’s blocking brake delivers a holding torque of 60 Nm, giving the axis sufficient reserve against gravitational or process forces when stationary. Alignment with the driven machine is simplified by a centering diameter of 180 mm, which is a common flange size for this frame class. Heat generated in the stator is removed by natural convection, allowing installation without forced-air ducts as long as ambient airflow is unobstructed. During normal operation, the rotor reaches 3000 rpm at nominal current, a speed range matched to medium-inertia loads in indexing tables and gantries. The ED winding code identifies the electromagnetic layout used to balance torque output with permissible current density.

Electrical terminations are routed through a connector on side A, keeping power cables on the driven side of the machine and shortening conduit runs. Position and speed feedback are available because the unit is supplied with tacho feedback and a second shaft end; the tachogenerator outputs 3 V/1000 rpm, giving drive controllers an analog reference proportional to actual speed. Classified as a motor for analog drives, it integrates directly with legacy current-controlled amplifiers. The length code C and the 112 frame size provide moderate rotor inertia that supports quick reversals without overshoot, while the tacho quality is rated standard for consistent gain settings across identical axes.
