Product Description:

The MAC122B-2-PD-4-C/130-B-0/DT520IV/S005 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, this motor converts commanded current into controlled torque and speed for axis control in industrial automation lines, packaging equipment, and material-handling cells. Its mechanical interface and electrical features follow the legacy MAC platform, supporting use in compatible motion-control equipment. It is suited to positioning and speed-regulated axes that require stable feedback and predictable operating behavior during repeated production cycles.

It is supplied without a blocking brake, so the machine must rely on external holding methods when power is removed. Internal ventilation is supported by a blower that runs on AC 115 V, ensuring continuous airflow through the stator windings during high-duty cycles. Heat is removed by axial surface cooling, so mounting clearances must allow unobstructed airflow along the motor housing. A 130 mm centering diameter helps align the motor with standard flange seats during installation. During continuous operation, the motor has a nominal speed of 1500 rpm. This cooling arrangement supports stable operation in applications that run for long periods under sustained load.

Control feedback is delivered through tacho feedback with an incremental or absolute encoder, letting the analog drive close both speed and position loops through one feedback system. Power conductors enter the housing through a connector on side B, which can simplify cable routing when the motor is installed with the fan toward the workspace. For velocity monitoring, the integrated tacho generator provides 3 V/1000 rpm as a proportional speed signal. The electromagnetic design uses the PD winding code, which matches the electrical characteristics expected by compatible MAC amplifiers. This feedback and winding combination supports consistent motor response in established analog servo applications.
