Product Description:

The MAC090B-0-PD-2-C/130-B-1/S012 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a compact rotary actuator, it delivers commanded torque and speed profiles in industrial automation lines such as packaging, material handling, and machine tools. By combining a permanent-magnet rotor with analog velocity feedback, the motor provides closed-loop motion control for tasks that demand moderate inertia and repeatable positioning. Its layout suits machinery that uses classic servo hardware and requires predictable response during repeated starts, stops, and short indexing moves.

The mechanical interface centers on a pilot of 130 mm, allowing direct seating in gearboxes or flanges without shims. Its winding designation of PD identifies the resistance and inductance set used with legacy MAC drive modules. Cooling is handled by natural convection, so heat leaves the housing through surface radiation and ambient airflow without an external blower. During continuous operation, the shaft reaches a nominal speed of 1500 rpm, providing a stable operating point for standard 50/60 Hz drive frequencies. For wiring convenience, the power cable exits through a connector on side B, keeping the opposite end free for feedback and brake leads when the motor is mounted in tight cabinets.

The speed loop uses a DC tachogenerator that supplies 3 V/1000 rpm. This signal, combined with internal tacho feedback, lets the drive regulate velocity without a digital encoder, and the control system receives a simple analog speed reference from the motor. A blocking brake is present, so the motor can hold load torque during power-off on vertical axes or other applications that need the shaft to remain at rest. Classified as a motor for analog drives, the unit remains compatible with classic VT-160 and similar controllers that use proportional command voltages to close the current loop.
