Product Description:

The MAC112D-0-ED-4-C/130-B-2/WI520LV/S013 is a servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it translates current-mode commands from legacy drive controllers into controlled rotary motion. It is intended for positioning, indexing, and speed-controlled axis duties in automated production equipment. Its control style fits installations that continue to use analog amplifiers rather than newer digital servo platforms.

This model integrates a heavy-duty blocking brake capable of holding 60 Nm when the shaft is at rest, supporting vertical axes and emergency stops. The brake is used for holding at standstill, while motion control is handled by the external drive. Thermal energy produced during operation is dissipated by natural convection, eliminating the need for forced airflow or liquid coolers. Under rated conditions, the rotor reaches 3000 rpm, a speed suited to velocity loops driven by analog reference signals. Precise concentric mounting is aided by a 130 mm centering diameter on the front flange, which helps keep coupling misalignment low. Electrical behavior corresponds to winding code ED, which sets resistance and inductance values to match MAC-series power amplifiers.

Power cabling attaches through a connector on side B, simplifying wiring when the feedback devices occupy the opposite face. The feedback system combines tachogenerator output with encoder data and uses tacho feedback with an incremental or absolute encoder to provide both speed and position information. The tachogenerator delivers 3 V per 1000 rpm, supplying a proportional voltage that stabilizes analog velocity control. Housing dimensions follow motor size 112, and length code D adds stack height for higher torque without changing the mounting footprint. Separating the power connection from the feedback devices can help keep cable routing orderly in compact machine frames.
