Product Description:

The MAC090B-0-PD-1-B/110-B-0/I00625 is an AC servo motor developed by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It turns controlled drive currents into regulated shaft torque and speed for positioning or process-driven motion tasks on automated machinery. Typical duties include indexing tables, material-handling axes, and other machine modules that require precise bidirectional rotation. The design keeps motion-control electronics in the external drive, so the motor can serve as a compact actuator in systems that rely on centralized regulation.

The electromagnetic configuration uses the PD winding code, which sets the motor's voltage constant and nominal current demand for the analog amplifier. Under rated excitation, the rotor reaches a nominal speed of 1500 rpm, allowing direct coupling to gear stages that are optimized around this base speed. Heat generated in the stator is removed by natural convection, so installation must leave free airflow around the housing instead of relying on forced cooling. Position and velocity loops in the drive are closed with incremental encoder feedback, and the encoder supplies phase-shifted pulse tracks that the controller converts to counts per revolution. For coarse speed monitoring, the built-in tacho produces 3 V/1000 rpm at the motor terminals. Mechanical centering during mounting is simplified by the 110 mm centering diameter on the flange. These feedback signals allow the connected controller to track shaft motion without adding extra electronics inside the motor housing.

All power conductors reach the windings through a connector on side B, a layout that keeps cabling on the non-drive face of the machine frame. Because the unit is a motor for analog drives, its electrical interface is limited to power and incremental feedback lines, and there is no embedded fieldbus or parameter memory. The motor ships with no blocking brake, so external holding mechanisms must be used whenever vertical loads or safety stops are required. This arrangement suits applications where brake holding is handled elsewhere in the axis design.
