Product Description:

The MAC025C-0-QS-4-E/040-A-0/WI652LV is a compact AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is designed for analog drives and interfaces with voltage-commanded amplifiers to deliver closed-loop motion in industrial machinery. Its role is to supply controlled torque and speed so that automated tooling, feeders, and gantry axes can follow position or velocity commands with minimal error during repeated operating cycles.

The mechanical build follows the MAC size coding, with the unit designated size C and the stator stack cut to length 025. This combination gives the motor a narrow frame and a short magnetic core, which helps reduce rotor inertia for rapid start-stop motion and responsive axis control. Heat produced by copper losses is removed by natural convection, so the housing can operate without an external blower or liquid cooling system. Installation is also simplified by a single connector on side A, which helps keep cable routing straightforward when the drive is mounted on the same side of the machine. For holding functions, the motor is supplied without a blocking brake, so any stationary holding force must come from drive torque or an external mechanical device.

The position loop is supported by a tacho feedback encoder, and the motor carries an incremental encoder with standard mounting hardware that keeps the overall package compact. This arrangement supports stable speed regulation at low shaft speeds and maintains compatibility with analog control architecture commonly used with this motor family. Because the winding and feedback combination is intended for analog amplifiers, the unit is recognized as an analog drive motor in matching drive setups. The feedback cable reaches the controller through the same side-A routing path as the power connection, which helps reduce cable congestion inside compact control enclosures.
