Product Description:

The MAC041C-0-LS-2-E/050-A-0 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It acts as the electromechanical output stage in analog positioning loops, converting drive current into precisely metered shaft torque for light-duty axes on pick-and-place, printing, and small machining equipment. Power conductors exit through a Side A plug-in connector, which can simplify cable routing when the motor is mounted with its shaft toward the machine center. Its compact format also helps it fit smaller machine sections where available space and moving mass must remain limited.

Cooling is handled exclusively by natural convection, so installation must allow free airflow around the housing to maintain winding temperature. The frame is designated C, and the laminated stack length code 041 gives the rotor a short axial dimension that favors compact machine layouts. Inside that frame, the stator carries the LS winding set, whose voltage and current profile matches the characteristic output of legacy analog MAC drive amplifiers. Because no external fan is used, surrounding panels and nearby components should not restrict the air path around the motor surface. These physical and electromagnetic properties set the continuous torque capability, usable speed band, and thermal load that the connected drive must handle.

Mechanical holding force is not supplied because the motor has no blocking brake, so any static load retention must be provided by an external clamp or by drive-applied torque. Speed feedback is derived from a permanent-magnet tachogenerator, listed as tachofeedback, allowing the analog controller to close the velocity loop without digital encoders. That feedback method supports stable speed regulation in systems that rely on continuous motor-generated velocity signals. The unit is categorized as a motor for analog drives, so its electrical characteristics are tuned for voltage-controlled amplifiers rather than modern field-oriented inverters. By relying on passive cooling and omitting a brake assembly, the design remains lightweight, reduces maintenance points, and suits continuous-duty automation where fast response and low inertia are priorities.
