Product Description:

The MAC115D-0-CS-4-C/130-B-0/WI520LV/S001 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it accepts ±10 V velocity or position references from legacy control amplifiers and converts them into regulated torque for industrial axes. The mechanical format combines a size 115 frame with an elongated D-length lamination stack, offering higher continuous power than shorter variants while remaining compatible with common flange patterns in metal-cutting, material-handling, and packaging equipment.

A centering pilot of 130 mm keeps the housing concentric to mounting flanges, reducing misalignment forces on the shaft bearings. Thermal energy is dissipated by natural convection, so airflow around the ribbed stator surface must not be obstructed. The shaft is furnished with a DIN 6885 keyway that helps lock couplings against slip during high-cycle reversals. Under rated excitation, the rotor reaches 3000 rpm, allowing the motor to track analog command voltages across typical drive operating ranges. Main power conductors exit through a connector on side B, which helps keep the cable bundle clear of the driven load and supports cleaner routing into cable tracks.

Speed feedback is generated by a tacho generator that supplies 3 V/1000 rpm, while incremental position information is delivered through an incremental encoder with standard mounting so legacy controllers can implement velocity and position loops without additional converters. The winding code CS indicates the resistance and inductance values expected by matching MAC analog amplifiers. The frame designation 115 provides moderate rotor inertia, balancing rapid acceleration with stable velocity regulation for medium-duty axes that cycle continuously throughout a production shift.
