Product Description:

The MAC112B-0-GD-4-C/130-A-1/WI522LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a drive element for analog velocity and position loops, the unit converts ±10 V commands from legacy servo amplifiers into regulated rotary motion for machine tools, printing presses, and packaging equipment. Integrated tacho and encoder electronics inside the rear cover provide the feedback signals needed to maintain speed, follow motion profiles, and detect positional errors. This arrangement supports continued use in systems that rely on established analog control structures.

Mechanically, the rotor is held at rest by a built-in blocking brake rated for 45 Nm, allowing load retention when power is removed. Alignment to gearboxes is aided by a centering diameter of 130 mm that matches the flange pattern of its frame. Heat generated in the stator is dissipated through natural convection, eliminating the need for external blowers. The electromagnetic core corresponds to frame size 112, and winding code GD indicates a resistance and inductance combination suited to mid-range speeds with elevated standstill torque. These characteristics make the motor suitable for installations that need predictable thermal behavior and stable low-speed operation.

Electrical interfacing is simplified by a power connection on connector on side A, allowing straight cable routing along the machine bed. Overall length code B gives the motor its corresponding housing length and rotor inertia for this frame. Feedback is delivered by tacho feedback with an incremental or absolute encoder, supporting analog velocity regulation and position monitoring. Tacho quality is listed as standard, which suits conventional analog loop operation. As a motor for analog drives, the model allows existing motion systems to remain in service without changes to the controller architecture.
