Product Description:

The MAC071B-0-PS-4-C/095-A-1/AM154SG/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Delivered as a motor for analog drives, it converts current-loop commands into controllable torque for positioning tables, pick-and-place axes, and other industrial automation stations that rely on precise speed and holding functions. The built-in blocking brake and multi-mode feedback hardware allow the driven shaft to accelerate, stop, and maintain position under closed-loop control routines. Because it is intended for analog drives, motion is commanded through continuous control signals rather than a networked digital interface.

This model reaches a nominal speed of 4000 rpm, giving motion controllers a predictable velocity reference across its continuous operating range. A centering diameter of 95 mm aligns the frame with standard machine flanges, and motor size 071 with length B gives the unit its mounting depth. The integrated brake supplies 3 Nm of static holding torque so vertical loads remain stationary when the drive is de-energized. Heat is removed by natural convection, eliminating the need for external blowers or liquid circuits. The PS winding code indicates the stator configuration used with matching drive voltage and current. For velocity feedback, the internal tacho generator outputs 1.5 V/1000 rpm, providing a proportional signal that helps the controller regulate dynamic speed changes without overshoot.

The mechanical interface uses a DIN 6885 keyway so torque can be transferred directly into couplings or pulleys without slip. Position verification is refined by an integrated absolute encoder, allowing the axis to report its angular location immediately after power-up without a homing cycle. Power conductors enter through a connector on side A, which orients the cable away from moving machine parts and simplifies access to the connection point.
