Product Description:

The MAC112D-0-ED-4-C/130-A-2/W1520/S013 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. The designation indicates that it is a motor for analog drives, where commanded current is translated into controlled torque and speed for coordinated axis movement. With length code D and frame size 112, the housing provides the mechanical envelope needed for high continuous output while remaining compatible with standard MAC mounting flanges. In industrial automation, this motor converts commanded current into precise shaft rotation for presses, handling axes, and machine tools that require stable closed-loop motion across a wide operating speed range.

The motor uses a heavy-duty blocking brake to hold the shaft when the drive is disabled. Its braking torque reaches 60 Nm, which helps resist back-driving on vertical axes or other loads that can move under gravity. A centering pilot of 130 mm helps align the motor with adjacent mechanical components and supports coaxial mounting. During operation, the rotor can sustain a nominal speed of 3000 rpm, making the unit suitable for rapid point-to-point moves. Heat generated at that speed is removed by natural convection, so the motor should be installed where surrounding air can circulate freely.

The three-phase stator windings use code ED, which identifies the resistance and inductance values expected by the paired analog amplifier. For power cabling, the plug is located at connector on side A, keeping cable routing on the same face as the brake terminal. Rotor speed and position are monitored through tachofeedback with an incremental or absolute encoder, giving the drive the information needed for regulated motion. The tacho generator supplies 3 V/1000 rpm as proportional velocity feedback, which supports stable analog speed control without requiring external sensing devices in typical closed-loop operation.
