Product Description:

The MAC090C-0-KD-1-B/110-A-1/J1000 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a compact synchronous unit, it interfaces with analog velocity or current-loop drives to convert electrical commands into controlled rotary motion. In automated machinery, this motor supplies continuous shaft power, holding torque when idle, and repeatable speed references so that conveyors, indexing tables, and tooling spindles follow the setpoints generated by the supervisory controller.

At a nominal speed of 1500 rpm, the rotor reaches its rated synchronous velocity under continuous load conditions, providing predictable mechanical output for tuning analog regulators. The internal tacho generator produces 3 V/1000 rpm, allowing the drive electronics to derive a proportional speed feedback signal without an external sensor. Heat produced in the stator is removed by natural convection, so the motor can be mounted without forced-air accessories when ambient airflow is sufficient. Position referencing is supplied through incremental encoder feedback, which transmits pulse trains for fine-resolution commutation and motion monitoring. Mounting into machine frames is simplified by a centering flange sized at 110 mm, which aligns the shaft accurately with coupled loads.

The mechanical package is delivered with a blocking brake, enabling the shaft to remain locked during power-off or emergency stops in vertical or suspended axes. Power conductors exit through a connector on side A, keeping cable routing consistent with other MAC family motors and reducing enclosure depth. The motor uses the KD winding, and this winding code corresponds to the rated voltage, current, and torque constants required by the associated analog amplifier. The designation motor for analog drives confirms compatibility with legacy transconductance controllers that rely on ±10 V command structures and analog servo loops.
