Product Description:

The MAC090B-0-PD-1-B/110-A-0/J1000/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. The unit is intended for closed-loop motion tasks in industrial automation, where precise velocity regulation and high positioning repeatability are required by analog drive controllers. In typical use, it works with external servo electronics that regulate torque and speed from command signals generated by the motion system. This makes the motor suitable for packaging equipment, transfer axes, and other machines that depend on repeatable rotary movement.

The housing is aligned to the machine interface by a centering diameter of 110 mm, allowing rigid mounting without radial misalignment. During continuous operation, the rotor turns at a nominal speed of 1500 rpm, which matches common gear ratios and operating ranges in machine tools and handling modules. A built-in tacho generator delivers 3 V/1000 rpm, and this linear voltage signal is used by analog regulators to establish speed feedback without digital conversion. Coil set designation PD identifies the winding resistance, inductance, and thermal limits that the drive must observe when setting current loops. Rotor position is tracked through incremental encoder feedback, enabling the controller to detect phase angle and issue commutation commands with low delay.

Thermal losses are removed by natural convection, so the motor can be installed on compact plates without forced airflow hardware. The three-phase supply is routed through a connector on side A, simplifying cable runs when multiple axes are stacked in a single cabinet. The design is specified without a blocking brake, so systems that require holding torque during power-off must use external clamping or maintain drive current. Its mechanical and electrical interfaces classify the unit as a motor for analog drives, which keeps it compatible with legacy Indramat drive cards that use voltage and tacho signals rather than fieldbus networks. This arrangement suits applications where straightforward integration with established analog control hardware is required.
