Product Description:

The MAC112C-0-HD-2-C/130-A-2 is an AC servo motor manufactured by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Built for analog drives, it converts voltage commands into controlled rotary motion for positioning tables, pick-and-place arms, and similar automation axes. Its integrated blocking brake and tacho generator support older velocity-control systems that still rely on direct speed feedback rather than digital encoder data. This arrangement allows the motor to serve equipment that uses established analog control architecture and conventional speed-loop regulation.

A heavy-duty blocking brake is integrated so the shaft remains stationary when power is off. Its holding capacity is rated at 60 Nm, allowing vertical loads to stay locked without external clamps. The motor flange provides a centering diameter of 130 mm, which helps seat the housing accurately against machine frames or gearheads. Heat is removed through natural convection, eliminating auxiliary fans and keeping the motor suitable for installations that depend on passive cooling. At rated excitation, the rotor reaches 2000 rpm, supporting mid-speed machining and handling cycles. Power conductors are routed through a connector on side A, which helps keep supply wiring separate from feedback lines and can simplify cable routing in compact assemblies.

Velocity control in analog loops is realized through tacho feedback. The generator delivers 3 V/1000 rpm with standard linearity, giving the drive a predictable speed signal during acceleration, steady running, and deceleration. The motor uses length code C and frame size 112, which indicate the housing depth and mounting pattern used by this unit. The stator uses winding code HD, matching the electrical characteristics expected by the associated drive family. These codes correspond to the physical package and electrical setup used on this motor.
