Product Description:

The MAC112D-0-ED-2-C/130-B-0 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts electrical input into controlled mechanical rotation for positioning and velocity tasks in automated machinery. The unit is selected when precise speed regulation and direct coupling to analog controllers are necessary in conveyor lines, packaging cells, and machine tools. Its format suits machine platforms that rely on analog command signals and conventional motor feedback.

The housing follows the D length code and aligns to mounting surfaces through a centering diameter of 130 mm, helping maintain shaft concentricity during installation. Heat dissipation relies on natural convection, so no external blower or liquid circuit is required and the mounting space must allow free air circulation. This cooling method keeps the motor mechanically simple and avoids auxiliary fan wiring. Under rated load the rotor reaches 3000 rpm, and electrical power is supplied through a connector on side B to simplify cable routing away from the driven shaft. For velocity feedback, the integrated tacho generator delivers 3 V/1000 rpm, giving the analog drive continuous speed information.

Because the motor has no blocking brake, the mechanical load must be held by drive current or an external clamp when power is removed. This arrangement is common in applications where the axis is supported by a gearbox brake or another holding device. The frame code 112 gives the motor a stator cross-section capable of higher continuous torque than smaller MAC models, while the winding set marked ED adjusts phase resistance and inductance for medium-voltage analog amplifiers. The motor uses standard tacho feedback, which is suitable for speed loops that need linear response but not encoder-level resolution.
