Product Description:

The MAC112D-0-ED-4-C/130-A-0/WI520L/S05 is a Bosch Rexroth Indramat servo motor supplied within the MAC AC Servo Motors series. It is identified by the manufacturer as a motor for analog drives, allowing speed and torque regulation through legacy amplifier modules in automated machinery. Within an installation, this unit converts electrical power into precise rotary motion so that conveyors, press axes, or handling gantries can follow programmed velocity profiles.

The stator housing sits on a centering flange that measures 130 mm, providing positional repeatability when the motor is bolted to a gearbox or machine frame. Heat produced by the windings leaves the enclosure by means of natural convection; no fan or liquid circuit is required, so ambient airflow must remain unobstructed. During rated operation, the rotor turns at 3000 rpm, a speed selected for medium-inertia loads that need quick acceleration without excessive gear reduction. Power leads exit through a connector on side A, which simplifies routing when cable trays are placed along the drive end of the machine. The ED winding code indicates the electromagnetic characteristics used with compatible Indramat MAC drives that supply the correct voltage constant and current limit.

The motor has no blocking brake, so mechanical holding devices must be added if back-driving is a risk. The frame size is 112, indicating the stator diameter used across this portion of the series and setting expectations for torque capacity and mounting pitch. Rotor position is reported by an incremental encoder that bolts to the housing with standard alignment, allowing the controller to evaluate phase angle for commutation. A built-in tacho generator delivers 3 V/1000 rpm, giving the analog drive immediate velocity feedback, while the unit’s tacho quality is rated as standard for general-purpose servo loops.
