Product Description:

The MAC112C-0-ED-4-C/130-A-1/WI520LV/S0 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drives and delivers controlled torque and speed to machine axes in automated production equipment. When paired with legacy analog servo amplifiers, the motor converts electrical command signals into rotary motion for positioning, indexing, and speed-controlled conveying tasks. It also includes rotor position feedback and a mechanical holding function, which helps keep the axis stable during power loss or when the drive is disabled.

A blocking brake rated at 45 Nm provides holding torque so the shaft can remain fixed when motion must stop. A centering pilot of 130 mm supports accurate alignment to a gearbox or mounting surface without added bushings. Heat is removed by natural convection, so the motor does not require an external blower or coolant lines for standard operation. The housing fits within the size 112 frame, which gives it a compact footprint for its power class. Under continuous operation, the motor reaches a nominal speed of 3000 rpm, making it suitable for medium-power axes that require steady velocity response.

The built-in tachogenerator provides 3 V/1000 rpm to the analog drive for proportional speed feedback during closed-loop control. The motor uses winding code ED, which corresponds to electrical characteristics matched to standard MAC power modules. Power conductors connect through a threaded connector on side A, which allows the cable to run parallel to the motor axis. Position feedback is supplied by an integrated incremental encoder, which supports precise motion control without requiring a separate external sensor. This arrangement helps the motor serve packaging systems, tooling stations, and other factory automation equipment that relies on repeatable axis motion.
