Product Description:

The MAC112C-0-ED-4-C/130-A-1/WI517LX is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts the current issued by legacy servo amplifiers into controlled torque and speed for machine axes, material-handling carts, or packaging spindles. The unit forms the electromechanical interface between the controller and the load, allowing closed-loop motion tasks that require repeatable positioning and steady velocity tracking in industrial automation cells. Because it is intended for legacy analog drive systems, the motor relies on external control electronics to regulate current and interpret feedback during motion. Its compact frame allows direct mounting on machinery where installation space is limited.

Frame size 112 sets the flange pattern, while body length C establishes the motor's overall length without increasing its width. A centering diameter of 130 mm aligns the shaft precisely with the mating gearbox or machine face. The centering fit helps maintain shaft alignment and reduces coupling stress during continuous operation. The electromagnetic layout uses winding code ED, which matches the stator characteristics to compatible analog drive outputs. The motor is intended for nominal operation at 3000 rpm. Power leads exit through a connector on side A, which can simplify cable routing along a machine bed. The motor uses a standard tacho configuration for stable speed feedback in continuous duty.

The unit is delivered with a blocking brake that produces 45 Nm of holding torque, permitting vertical-axis retention when power is removed. Heat is removed by natural convection, so the installation must allow free air circulation around the housing. Speed monitoring is supported by a tacho generator that outputs 3 V/1000 rpm, and the feedback assembly supports an incremental encoder for position signals used by legacy analog controllers. The encoder and tacho signals share a multi-pin interface near the power connection. This arrangement keeps the feedback wiring compact without changing the motor's external footprint.
