Product Description:

The MAC112B-0-LD-4-C/130-A-0/WI520LV/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is designed for analog drive controllers that regulate current and voltage, allowing the motor to produce precise rotary motion in automated presses, packaging stations, and transfer lines. Integrated feedback hardware supplies speed and position data directly to the drive, eliminating the need for separate transducers and simplifying machine wiring. The motor supports closed-loop operation in machinery that requires controlled acceleration, stable velocity, and repeatable positioning under changing loads.

The electromagnetic circuit uses winding code LD, which matches the stator impedance and back electromotive force to controllers operating in the 40 to 60 A range. A centering diameter of 130 mm aligns the flange with gearboxes or mounting plates while limiting radial runout at the coupling. Heat produced by copper losses is removed through natural convection, so the motor does not require an external blower or liquid-cooling loop. At a nominal shaft speed of 2000 rpm, the motor can follow velocity commands commonly used by material-handling axes while keeping commutation frequencies within the regulator’s operating bandwidth. The frame size 112 provides a balance between torque capacity, motor mass, and installation space for medium-duty machinery. Its B-length housing accommodates a midrange magnetic stack that supports continuous torque without adding unnecessary axial length.

Mechanical power is transmitted through a DIN 6885 keyway, allowing secure engagement with pulleys, pinions, or rigid couplings without relying only on clamping friction. The integrated tachometer produces 3 V/1000 rpm, providing a proportional speed signal for the velocity control loop. Power conductors enter through a connector on side A, which helps keep the cable route clear of adjacent axes installed near the opposite side of the housing. Rotor position is monitored by an incremental encoder, enabling the controller to track shaft movement and regulate positioning during operation. The motor does not include a blocking brake, so vertical or suspended loads require an external holding device when power is removed. Standard tachometer quality supports general automation applications in which speed ripple must remain within normal operating tolerances.
