Product Description:

The MAC112B-0-PD-2-C/130-A-0/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive systems, it converts current-loop commands from a drive controller into precise shaft rotation for automated tooling, material handling, and general machinery. A built-in tachogenerator supplies velocity feedback so the amplifier can correct speed changes during load variation and maintain closed-loop speed regulation. Because that feedback device is integrated into the motor, the unit suits multi-axis equipment that relies on a direct internal speed signal rather than a separate external sensor.

The motor uses a 130 mm centering diameter so the housing seats accurately against machine flanges, and the size 112 frame establishes the overall stator envelope. It has a PD winding that matches the electrical characteristics expected by compatible analog drives. Under rated excitation, the rotor reaches a nominal speed of 1500 rpm, giving a steady operating point for applications tuned around that shaft speed. Cooling is handled by natural convection, which releases heat through the housing without auxiliary airflow, while the B length version provides a longer active stack for greater torque capability than shorter versions in the same frame.

The motor is supplied without a blocking brake, so holding force during power loss must come from the driven mechanism or another external device. Speed information is returned through tacho feedback, and the generator output of 3 V/1000 rpm gives the drive a linear velocity signal across the normal operating range. Power conductors leave through a connector on side A, which helps keep cable routing organized when the motor is mounted in compact machine spaces. This cable position can also reduce interference between the connection area and nearby machine components.
