Product Description:

Bosch Rexroth Indramat manufactures the MAC112D-0-ED-4-C/130-B-0/W1520LV/S005 servo motor within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts command voltages from legacy amplifiers into regulated torque and speed, letting automated machinery position tools, conveyors, or auxiliary axes with repeatable accuracy. The frame follows size 112 geometry and carries the D-length stator, which gives the motor a solid balance of continuous torque capacity and overall mass for mid-range motion duties. It can be used on indexing tables, feed axes, and transfer systems where stable speed control is important during repeated cycle changes.

Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, which helps match the motor to common belt, screw, and gearbox ratios. Thermal energy leaves the housing by natural convection, so unobstructed airflow around the finned surface is required during operation. A flange-mounted 130 mm centering diameter aligns the motor concentrically with adjacent machine plates for accurate installation. Incoming three-phase power is fed through a connector on side B, keeping cable routing consistent when the shaft faces the user. The unit is supplied without a blocking brake, so static load retention must rely on external clamps or continuous drive torque during power loss.

Velocity and position signals are generated by tacho feedback with an incremental or absolute encoder, permitting analog speed loops or higher-resolution motion controllers to use the same motor. Shaft torque is transferred through a DIN 6885 keyway, allowing the use of standard metric couplings, pulleys, and gear inputs in conventional machine layouts. The integral tachogenerator outputs 3 V/1000 rpm, giving the drive a proportional voltage for precise velocity regulation across the operating range. This analog signal helps the amplifier correct speed deviations caused by changing load conditions. The motor uses ED winding, which sets the electrical characteristics expected by compatible analog amplifiers.
