Product Description:

The MAC112D-2-FD-4-C/130-A-0/WI520LV/S005 is a servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive controllers, it provides closed-loop torque and speed control for industrial axes that require accurate continuous-duty operation. An axial surface cooling system with an external blower carries heat away from the stator, which helps the motor maintain its rated output in enclosed machine frames. This arrangement supports repeatable motion on packaging, handling, and other automated equipment where the drive must respond smoothly to changing load conditions.

The motor delivers a continuous shaft torque of 38.0 Nm while drawing 56.0 A at standstill. An auxiliary blower rated at AC 115 V supports the axial surface cooling path by forcing air along the housing ribs. The nominal speed is 2000 rpm, which suits many general industrial motion systems that use analog servo control. A centering diameter of 130 mm helps align the motor on precision mounting plates, and a DIN 6885 keyway transfers torque to the driven load. Power is connected through a connector on side A, which keeps cable routing straightforward when the motor is installed in compact machinery.

During acceleration, the drive can supply up to 260 A of peak current for short overload periods. The winding has an inductance of 1.8 mH and a phase resistance of 0.110 ohm, and the rotor inertia is 0.0230 kgm². The frame size is 112 with length D and winding code FD, and the motor is supplied without a blocking brake, so holding torque must come from the drive or the machine. Standard tachofeedback provides 3 V/1000 rpm, and an incremental encoder with standard mounting returns position information to the controller. The torque constant is 0.760 Nm/A, and the thermal time constant is 120 minutes. Rapid speed changes are supported by the combination of peak current capability and rotor inertia during start-stop duty.
