Product Description:

The MAC090B-0-PD-2-C/110-B-2/S013 is a closed-loop servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. The motor supplies continuous rotary motion to indexing tables, handling axes, and packaging equipment that rely on tight velocity and position control. Integrated tachometer feedback allows the associated analog drive to monitor shaft speed directly, keeping cycle times predictable while minimizing overshoot in dynamic moves.

This model includes a heavy-duty blocking brake that clamps the shaft when power is removed so suspended or vertical loads do not drift. A centering collar diameter of 110 mm aligns the stator housing with machine frames, ensuring repeatable concentricity between the motor and driven mechanics. Heat produced by copper losses is released through natural convection, so no external fan or liquid circuit is required. Under rated conditions, the rotor turns at a nominal speed of 1500 rpm, a value that matches many gear ratios found in transfer lines and material-feed drives. All three power phases terminate through a plug oriented toward the non-driven end as a connector on side B, which eases cable routing in crowded enclosures.

The motor is classified as a motor for analog drives, so its current loop is closed in the external controller rather than on an embedded processor. Speed feedback accuracy is supported by a tachogenerator that outputs 3 V/1000 rpm, and this standard tacho signal is sufficient for most velocity regulators used with this family. Coil impedance corresponds to winding code PD, allowing the drive to estimate thermal load from current measurements without additional sensors. The feedback assembly is delivered with tachometer feedback, providing a direct voltage proportional to speed and eliminating the need for separate incremental encoders in applications where only velocity control is required.
