Product Description:

Bosch Rexroth Indramat builds the MAC112D-0-EG-4-F/130-B-1/WI511LV as part of the MAC AC Servo Motors series. This AC servo motor is configured for analog drives and converts commanded torque and speed into controlled mechanical rotation for production lines, packaging units, and material-handling axes. Its design combines motor windings with feedback devices so external control hardware can regulate motion accurately during continuous industrial operation. The unit is suited to applications that need stable servo response without adding unnecessary complexity to the drive system.

The motor includes a blocking brake rated at 45 Nm, which allows the axis to remain held when power is removed. Accurate mechanical alignment is supported by a 130 mm centering diameter that matches common flange patterns on machine frames. Heat from the stator is dissipated by natural convection, so no auxiliary fan or liquid cooling circuit is required. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, which supports responsive operation in mid-power axis duties. This combination of holding capability, passive cooling, and steady speed behavior makes the motor suitable for machines that run repeated motion cycles throughout the day.

Electrical power is connected through a connector on side B, which can simplify cable routing when the rear of the axis faces the cabinet. Velocity information is provided through tacho feedback with an incremental or absolute encoder, and the signal level of 3 V/1000 rpm remains proportional to shaft speed for analog control circuits. For position regulation, the motor uses an incremental encoder with standard mounting, allowing integration with common motion-control hardware. Winding code EG identifies the motor’s electromagnetic setup for this configuration. These features support stable speed feedback, consistent position tracking, and straightforward integration with compatible servo amplifiers.
