Product Description:

The MAC112D-0-ES-2-C/130-A-0 is a three-phase AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It converts drive current from companion analog controllers into controlled torque and speed, enabling precise feed axes, traversing carriages, and general automation stages to follow reference commands accurately. The motor couples directly to gearboxes, ball screws, or timing pulleys, delivering repeatable motion without open-loop slip, which is important for dimensional consistency and stable cycle times in production equipment.

Its mechanical interface uses a centering pilot of 130 mm, allowing the housing to seat concentrically in flange recesses and maintain alignment with downstream mechanics. The motor has a frame size of 112 and a length code of D, a combination that balances torque density with overall envelope dimensions. Heat leaves the stator through natural convection, so no auxiliary blower or liquid circuit is required in typical cabinet-free installations. The winding code is ES, which sets the phase resistance and voltage constant for use with designated analog drive modules. The motor has no blocking brake, so any vertical load must be secured by external means during power-off events.

Signal fidelity is reinforced by the built-in feedback channel, which combines rotor position sensing with tacho feedback. The tachometer furnishes real-time velocity data to the controller for smooth speed regulation during changing load conditions. Power conductors exit through a connector on side A, which simplifies cable routing when the drive cabinet is located to the left of the axis. As a motor for analog drives, its internal insulation system and sensor scaling are matched to voltage-controlled amplifiers rather than digital pulse trains. The tacho unit follows a standard quality grade, supporting consistent calibration throughout the product’s service life without requiring field adjustment.
