Product Description:
The MAC112B-0-GD-1-B/130-A-0-I01250 is an AC servo motor manufactured by Bosch Rexroth Indramat and included in the MAC AC Servo Motors series. It functions as a rotary actuator in industrial automation, converting current commands from the drive into controlled shaft movement for positioning tables, tool heads, and pick-and-place modules. Closed-loop operation is achieved by combining the motor’s electromagnetic design with external control electronics, allowing precise velocity and torque regulation throughout the working cycle. This operating method helps the motor respond consistently when load conditions change during repeated motion sequences.
The flange centering pilot is 130 mm, which helps keep the motor and coupled mechanics in accurate alignment. Heat generated in the stator is dissipated by natural convection, so installation should allow free air circulation around the housing. Rotor angle is reported through incremental encoder feedback, giving the drive a high-resolution signal for commutation and speed control. Frame size 112 corresponds to the outside diameter of the stator lamination pack and is associated with the mounting bolt pattern and power density of this motor. Mains conductors enter through a connector on side A, which places the power connection on that side of the housing for straightforward cable routing.
The mechanical build uses length code B, which gives the motor a medium axial stack that balances torque capability and rotor inertia. Electromagnetic characteristics follow winding code GD, matching phase resistance and inductance to legacy voltage-controlled amplifiers. The assembly is supplied with no blocking brake, so any load-holding requirement must be handled by external clamping devices or continuous current from the drive. The unit is classified as a motor for analog drives, which confirms compatibility with controller platforms that rely on analog command structure and matching motor constants. This makes the motor suitable for systems that continue to use established analog control architecture.
