Product Description:

The MAC112B-0-GD-2-C/130-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It functions as the rotary actuator in industrial automation systems that require precise velocity and position regulation through external drive electronics. By translating commanded current into controlled mechanical torque, the unit supports applications such as indexing tables, packaging lines, and material-handling axes where repeatable motion profiles are critical. The motor is intended for analog drive systems that use current command signals and external feedback processing to maintain stable motion during changing load conditions.

A centering diameter of 130 mm positions the housing accurately in a pilot bore, ensuring coaxial alignment with the driven machine element. Thermal energy leaves the frame by natural convection, so no supplemental blower or liquid circuit is necessary under rated load. The integrated tacho generator provides tacho feedback, delivering a proportional voltage signal that closes the speed loop in analog servo amplifiers. Frame size code 112 identifies the motor housing size and matches the flange and shaft proportions used for this version. Winding code GD indicates the coil impedance set, allowing the drive to reach nominal torque without exceeding permissible current. This arrangement supports steady operation without the added complexity of forced-air cooling hardware.

The motor uses stator stack length B, which provides an intermediate continuous torque level while keeping overall weight moderate. The power lead exits through a connector on side A, facilitating cable routing toward the machine's main cabinet. Operation is without a blocking brake, so holding force must come from the drive or external clamps when the shaft is stopped. Classified as a motor for analog drives, the unit accepts current commands instead of digital fieldbus signals and relies on standard tacho-quality feedback rather than high-resolution encoders for velocity control. This layout suits machines that need straightforward integration with legacy analog servo amplifiers.
