Product Description:

The MAC112B-0-GG-4-F/130-B-1/WI522LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it supplies closed-loop torque and speed control to older drive amplifiers still used in automated transfer lines, packaging stations, and index tables. By converting electrical input into precisely metered mechanical rotation, the unit serves as the main actuator in systems that require consistent positioning under varying load.

The motor frame carries size code 112 and length code B, giving a compact yet high-inertia stack matched to mid-range machine axes. A standard blocking brake is included, and its holding capability is rated at 45 Nm, so vertical loads remain stationary when power is removed. The flange has a centering diameter of 130 mm for repeatable alignment with gearboxes or mounting plates. Heat is removed by natural convection, eliminating the need for external blowers. Under continuous duty, the rotor reaches a nominal speed of 3000 rpm, a value selected for direct coupling to 1:1 belt drives. Power is delivered through a connector on side B, simplifying cable routing inside tight cabinets.

Signal hardware is arranged for tachometer and encoder feedback. The servo includes a tachogenerator that delivers 3 V/1000 rpm; this voltage slope lets analog controllers derive real-time speed. The tachometer is configured for increased smooth-running quality, reducing velocity ripple at low rpm. Position data comes from an incremental encoder mounted in the standard interface used for the series, and the wiring harness also supports absolute sensors when required. This combination lets the drive monitor both velocity and position through separate feedback paths during operation. Winding code GG identifies the resistance and inductance set used for balanced current draw and thermal rise during convection-cooled operation.
