Product Description:

The MAC112D-0-ED-4-C/130-B-2/WI520LV/S018 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It functions as a motor for analog drives, supplying closed-loop speed and position control for automated machine axes that require continuous operation and repeatable motion accuracy. A tacho feedback channel or an incremental or absolute encoder can be selected to match the drive controller’s regulation method.

The motor belongs to size 112, and its housing follows length code D, so the stack depth supports higher continuous torque without enlarging the flange outline. A centering diameter of 130 mm aligns the front face precisely on mounting surfaces, which helps reduce runout during installation. The rotor is optimized for high-speed duty, and the nominal operating velocity is 3000 rpm, a figure that balances dynamic response with bearing life in typical indexing or conveying tasks. Electrical characteristics are tied to winding code ED, which identifies the copper fill, slot pitch, and insulation parameters used by the companion analog drive to deliver the correct current and voltage profile.

A heavy-duty blocking brake is integrated to maintain shaft position when power is removed, and it supplies up to 60 Nm of static torque to counteract gravitational or process loads. Heat produced in the stator is removed by natural convection, eliminating the need for external blowers and allowing installation in sealed enclosures with adequate air clearance. Power conductors exit through a connector on side B, which keeps cable bends outside the fan-free airflow zone. The tacho channel delivers 3 V per 1000 rpm, providing a proportional feedback signal for analog speed loops while the incremental encoder supplies position data where required.
