Product Description:

The MAC112B-0-LD-4-C/130-A-1/WI524LX is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive amplifier commands into controlled rotary motion for robots, transfer lines, and other position-regulated axes in industrial automation. Its electrical design matches controllers that regulate current and velocity through continuous command signals. Integrated feedback channels allow the paired amplifier to monitor motion behavior during acceleration, steady speed, and positioning moves.

The integrated blocking brake delivers 45 Nm of holding torque, allowing vertical or suspended loads to remain stationary when power is removed. A centering diameter of 130 mm aligns the flange with machine mounts and helps maintain accurate installation. Heat is dissipated through the housing because the unit relies on natural convection, which permits installation without external fans but requires unobstructed airflow. Under rated conditions, the rotor reaches 2000 rpm, a speed that balances dynamic response with mechanical life for medium-inertia loads. Power conductors are routed through a connector on side A, which can simplify cable management when the motor is installed with its shaft facing forward.

The winding designation LD identifies the electrical setup used with legacy drive amplifiers. The motor has a frame size of 112, and the stator depth corresponds to length code B, giving a profile suited to moderate frame spaces. Speed feedback is supplied by a tachogenerator that produces 3 V/1000 rpm, while the incremental encoder provides position data for fine motion loops. This combination supports stable velocity feedback and helps the drive maintain consistent axis response during changing load conditions.
