Product Description:

The MAC090B-0-PD-1-B/110-A-0/I01250/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed to work with analog velocity and position controllers, the unit supplies controlled torque for feed axes, transfer systems, and automated processing stations in industrial plants. Its internal electromagnetic design transforms regulated current from a drive into rotary motion that can be coupled directly or through gear reduction to the mechanical load. This supports repeatable motion in applications that require steady speed control and accurate positioning during continuous operation.

The mechanical interface starts with a centering diameter of 110 mm, allowing the motor flange to fit standardized mounting faces without misalignment. The stator uses winding code PD, which sets the phase resistance and inductance for the intended continuous current rating. Heat is removed by natural convection, so additional fans or coolant lines are unnecessary when ambient airflow is available. Under rated conditions, the rotor reaches 1500 rpm, which establishes the base speed for the connected control loop. Power is brought in through a connector on side A, which keeps cables on the same end as the feedback line and helps simplify routing in compact machine layouts.

Position and velocity data are supplied through incremental encoder feedback, enabling the analog controller to calculate correction signals during operation. For an additional analog speed reference, the built-in tacho generator produces 3 V/1000 rpm, giving drive electronics a linear voltage proportional to shaft speed. Because the device is specified as a motor for analog drives, its signal levels and insulation design match the voltage and current ranges typical in those systems. The assembly is delivered without a blocking brake, so static holding force must be provided by external clamping hardware or by drive-applied torque when the application permits.
