Product Description:

The MAC112D-0-ED-2HC/130-B-2/S018 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts electrical input from classic velocity or current controllers into rotary motion for industrial positioning axes, conveyors, and forming equipment. Within these installations, the motor supplies continuous torque with closed-loop regulation, supporting repeatable cycle times and stable operation. Its layout suits machines that rely on established analog servo hardware rather than newer digital motion platforms.

The motor is fitted with a heavy-duty blocking brake that delivers holding torque of 60 Nm, so vertical or intermittent-duty axes remain stationary when the drive is de-energized. A shaft flange with a 130 mm centering diameter aligns the housing to machine frames and helps maintain accurate mechanical fit during installation. Thermal management relies on natural convection, allowing installation without forced-air ducts and reducing the number of external cooling components. Feedback is supplied by integrated tacho feedback, producing a proportional voltage for speed loops handled by analog amplifiers. Under rated excitation, the rotor reaches a speed of 3000 rpm, supporting common operating ranges for general industrial motion tasks. The mechanical build follows length code D, balancing rotor inertia and installation space.

Winding code ED sets the phase resistance and inductance used with legacy 300 V class analog drives. The tachogenerator issues a reference signal of 1.5 V/1000 rpm, giving the drive electronics a linear speed indication for fine velocity tuning during acceleration and deceleration. Power conductors exit through a connector on side B, which can simplify cable routing when the motor is mounted with the shaft facing the operator. This arrangement helps separate the connection area from the driven load and keeps the wiring path straightforward in tightly packed machine layouts.
