Product Description:

The MAC112C-0-ED-3-C/130-A-2 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is designed for analog drive controllers that require continuous velocity and torque control in automated production lines. The motor uses a C-length lamination stack and an ED winding, allowing it to reach its intended operating point while supporting the speed linearity expected from closed-loop tacho feedback. Its compact arrangement makes it suitable for positioning axes, indexing equipment, and other machinery that requires controlled rotary motion.

The internally fitted blocking brake develops 60 Nm of holding torque, allowing the axis to remain stationary when power is removed during vertical or indexing duties. A centering pilot of 130 mm supports accurate flange alignment and helps minimize radial loading on the bearings. Heat is removed through the housing by natural convection, so unobstructed airflow must be maintained around the motor frame. Under nominal conditions, the rotor reaches 3000 rpm, supporting applications with medium-inertia loads. Motion feedback is delivered by a standard DC tacho generator that outputs 3 V per 1000 rpm, providing the connected drive with a proportional voltage reference for closed-loop speed regulation. This feedback method allows the analog controller to monitor velocity changes and correct deviations caused by variations in the connected load.

The motor includes a heavy-duty blocking brake intended for demanding holding requirements. The feedback package is supplied with tacho feedback and a second shaft end, enabling an additional encoder or mechanical load to be coupled without modifying the motor. Power conductors enter through a connector on side A, which determines the cable-routing direction when the unit is installed in a compact machine layout. The frame designation 112 identifies the standardized motor frame size used for selecting compatible mounting hardware, couplings, and machine adapters. The second shaft end should remain properly guarded when it is not connected to another component, while the cable connection should be positioned to avoid excessive bending or mechanical strain during operation.
