Product Description:

The MAC112C-1-HD-4-C/130-B-1/WI518LX/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts current-mode commands from legacy drive controllers into controlled shaft rotation for industrial robots, pick-and-place stages, and printing equipment. The frame size 112 and length code C give the unit a medium mechanical envelope that fits common mounting patterns while keeping inertia moderate for responsive speed loops. Its layout suits automated equipment that needs repeatable motion, stable speed control, and straightforward integration with established servo platforms.

The integrated blocking brake is supplied as standard and applies 45 Nm of holding torque to secure the axis whenever power is removed. A forced-air blower rated at AC 230 V pushes airflow through the housing ribs, and the axial surface cooling arrangement helps maintain thermal balance at the nominal speed of 2000 rpm. Precise concentric alignment is aided by a 130 mm centering diameter machined into the mounting face. The motor also uses tacho feedback together with an incremental or absolute encoder with standard mounting, allowing closed-loop velocity or position regulation in analog drive systems. This combination supports controlled motion during both continuous running and repeated start-stop operation.

Mechanical power is transmitted by a shaft with a DIN 6885 keyway, which helps prevent slippage under cyclic loads. Speed information for the controller comes from a tacho generator that delivers 3 V/1000 rpm, matching the standard tacho quality used in the MAC family. Mains leads attach through a connector on side B, which can simplify cable routing in compact cabinets and tightly arranged machine sections. The HD winding code identifies the winding arrangement used in this motor, and it works with the C-length lamination stack to support the intended thermal performance. These features make the motor suitable for axis duties that require dependable feedback, secure torque transmission, and consistent behavior under changing loads.
