Product Description:

The MAC112B-0-GD-1-B-130-A-0-J625-S05 is an AC servo motor manufactured by Bosch Rexroth Indramat and delivered under the MAC AC Servo Motors series. It is engineered to pair with analog velocity or position drives, allowing closed-loop control of rotary axes in machine tools, printing lines, and material-handling stations. By converting electrical commands from the drive into controlled torque, the motor maintains commanded motion profiles that keep automated processes synchronized with sensors and actuators on the production floor.

This unit is built on a frame classified as size 112, giving a consistent mounting footprint for gearboxes or direct-drive couplings, while the centering pilot measures 130 mm to align the housing precisely to the machine plate. Heat generated in the stator windings is released through natural convection, eliminating the need for external blowers or liquid circuits in standard duty cycles. Rotor position is returned to the controller through incremental encoder feedback, so the drive can calculate speed and angle in real time. The motor is supplied without a blocking brake, so any load-holding function must be provided by external clamping or the drive’s active torque mode.

The motor has length code B, which balances continuous torque and overall weight for mid-range automation axes. Power terminations exit through a connector on side A, keeping high-current conductors on the same face as adjacent motors when multiple axes are arranged in a line. The design is categorized as a motor for analog drives, making it compatible with legacy MAC drive controllers that use ±10 V command signals. Its electromagnetic properties correspond to winding code GD, which indicates the resistance, inductance, and speed-torque gradient selected for the motor.
