Product Description:

The MAC112C-0-HD-4-C/180-A-0/WI522LV/S011 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 converts command voltages from legacy controllers into precise torque and velocity. This makes it suitable for positioning tables, gantries, and machine-tool spindles in industrial automation environments. The motor is intended for applications that rely on stable rotary motion and repeatable response from an external drive amplifier.

The motor uses an HD winding, which affects the electrical resistance, inductance, and thermal behavior seen by the connected drive. Under rated conditions, it reaches a nominal speed of 2000 rpm, a value that matches many conventional drive ratios and helps keep mechanical resonance outside the working band. A centering diameter of 180 mm aligns the stator housing concentrically with adjoining machinery to minimize vibration. Heat is removed by natural convection, so no external blower or liquid circuit is required. For velocity feedback, an integrated tacho generator produces 3 V/1000 rpm, giving analog drives a proportional voltage signal that supports stable speed regulation across the load range.

The power leads exit through a connector on side A, allowing conduit routing to remain clear of moving axes. Mechanical torque transfer is handled by a shaft machined with a DIN 6885 keyway, which provides positive engagement with couplings or pulleys. Position and speed can also be monitored through an incremental or absolute encoder with tacho feedback, providing additional feedback for closed-loop motion tasks. The motor has no blocking brake, so static holding force must be supplied by external clamping or drive torque when required. It has motor length C and motor size 112 for the intended frame arrangement, and it uses standard tacho quality for general-purpose accuracy.
