Product Description:

The Bosch Rexroth Indramat MAC112C-0-HD-2-C/130-B-0/S005 is part of the MAC AC Servo Motors series and is classified as a motor for analog drives. Designed for closed-loop position and velocity control in industrial automation, it translates armature current into precise rotary motion for gantries, packaging axes, and general machinery. The unit interfaces with Indramat analog amplifiers that modulate torque in real time so commanded speed and position can be followed with stable response. This operating style supports machines that need smooth acceleration, repeatable movement, and continuous correction when load conditions change.

Its centering diameter is 130 mm, which is the bore required on the mounting plate for accurate shaft alignment. Heat is removed through natural convection, so the motor operates without fan-driven airflow and avoids moving cooling parts. Because air is not forced through the frame, dust is less likely to collect on the laminations during operation. Rotor speed and direction are relayed by integrated tacho feedback, letting the controller respond quickly to load changes. The shaft reaches a nominal speed of 2000 rpm, and the tacho generator outputs 3 V/1000 rpm for the velocity loop. This feedback arrangement provides the amplifier with a direct signal for closed-loop speed regulation. Incoming power is connected through a connector on side B, which helps simplify cable routing when the motor is mounted near a machine wall.

The motor has no blocking brake, so external holding must be used when the application requires the shaft to remain fixed at standstill. The stator uses winding code HD, which indicates the electrical characteristics expected by matching drive cards, and the active magnetic length is coded as C. The selected winding and stack length affect the electrical match between the motor and the amplifier, especially in current response and sustained operation. In the size 112 housing, this arrangement suits medium-inertia axes that need steady speed control and a compact motor layout for analog drive systems.
