Product Description:

The MAC112D-0-ED-4-C/130-A-2/WI520LV/S018 is a servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it delivers rotational power to axis modules and standalone positioning tasks in industrial automation. It converts electrical input from a compatible analog amplifier into controlled rotary motion for feed axes, transfer units, and other repeatable machine movements. The motor uses a 112 frame with D length to reach the continuous speed and inertia range needed for medium-duty machine tools, packaging lines, and handling equipment.

Mechanical dimensions start with a centering diameter of 130 mm, which helps keep the motor aligned with mating flanges or gearboxes. Inside the stator, winding code ED identifies electrical characteristics matched to legacy analog drive cards and supports a nominal speed of 3000 rpm under rated voltage. Thermal management relies on natural convection, so heat dissipates through the housing without external blowers. This cooling method keeps the motor free of auxiliary fan hardware, and installation must allow unobstructed airflow for continuous duty. During emergency stops or vertical-axis holding, the integral brake provides 60 Nm of static torque, preventing shaft movement until drive current is reapplied.

A connector on side A carries the three-phase supply, keeping cables on the non-drive end for easier routing inside cabinets. Rotor position is monitored by an incremental encoder mounted in the standard interface, and for legacy speed loops a tacho generator outputs 3 V/1000 rpm with standard signal quality for repeatable velocity feedback. The heavy-duty blocking brake classification indicates that the brake is suitable for frequent clamping cycles on vertical axes. Placing the electrical connection on the non-drive end also helps separate motor cabling from the driven shaft and nearby mechanical components during installation.
