Product Description:

The MAC112C-0-EG-4-F/130-B-1/WI511LV is a servo motor produced by Bosch Rexroth Indramat for use with analog drive controllers. As a member of the MAC AC Servo Motors series, it supplies closed-loop rotary motion for positioning axes, feeders, and other automation tasks where consistent torque and speed regulation are required. Integrated electronic feedback lets the connected drive monitor shaft angle and velocity in real time, so the motor can follow programmed motion profiles in industrial machinery. This arrangement suits applications that require repeatable starts, stops, and speed changes under changing load conditions.

Its nominal speed is 3000 rpm. A centering diameter of 130 mm aligns the housing with machine flanges and helps maintain concentricity during rotation. Heat is removed through natural convection, so no external blower or liquid circuit is required. Because cooling depends on free airflow around the housing, the mounting area should not block heat dissipation from the motor surface. The three-phase power leads terminate at a connector on side B, which helps guide cable routing and keeps the electrical interface on one side of the motor. Winding code EG indicates the stator resistance and inductance combination used with standard MAC drives.

A blocking brake is supplied as standard and delivers 45 Nm of holding torque to secure vertical loads when the drive is disabled. For speed feedback, the unit contains a tachogenerator that produces 3 V/1000 rpm, and this signal is used by the drive to monitor actual shaft velocity. The motor has size code 112, and stator stack length code C indicates the active magnetic length. An incremental encoder is mounted in the standard position for position feedback during operation. The encoder and tachogenerator provide the feedback signals needed by analog drive systems for stable speed and position control.
