Product Description:

The MAC112D-0-ED-4-C/130-A-0/WI520LX/S005 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drives, it converts commanded current into precisely regulated mechanical rotation, allowing industrial automation equipment to position loads with high repeatability and quick dynamic response. In this role, it pairs with Indramat drive amplifiers to deliver constant torque across a wide speed range while remaining compatible with legacy analog control architectures. This type of motor is suited to positioning axes, feed systems, and transfer mechanisms that depend on stable speed control and predictable acceleration.

The unit reaches a nominal speed of 3000 rpm, which is used by the matching analog drive for velocity control. Heat generated by copper losses is dissipated through natural convection, so the motor can be mounted without external blowers when surrounding airflow is available. A 130 mm centering diameter aligns the housing to machine frames and helps keep radial runout within tolerance. Electrical behavior is identified by the ED winding code, which corresponds to resistance and inductance values used with the MAC112 drive family. For power, a sealed connector on side A routes the three-phase supply conductors away from the moving axis and simplifies cable management inside the cabinet. This arrangement supports installation in machine layouts where cable routing space is limited and a clean motor connection path is preferred.

The shaft uses a DIN 6885 keyway, giving a positive torque interface for pulleys or gearboxes. Because the motor is supplied without a blocking brake, holding torque during power loss must be provided by an external mechanism when the application requires it. Speed feedback to the analog drive is delivered by a tacho generator that produces 3 V/1000 rpm, and position information comes from an incremental encoder with standard mounting. This feedback arrangement suits systems that rely on separate analog velocity control and position supervision through the connected drive electronics.
