Product Description:

The MAC50B-0-J0-2-C/110-A-1 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is intended for analog drive systems where precise torque and speed regulation are handled by an external amplifier. This arrangement lets the motor respond to drive commands while supporting stable operation during varying load conditions. Within automated machinery, the unit provides closed-loop rotary motion for axes that require repeatable positioning, indexing, or continuous feed. Its mechanical design fits standardized mounting interfaces, allowing integration into conveyors, machine tools, and material-handling stations without additional adapters.

Mechanical alignment starts with a centering diameter of 110 mm, which positions the flange accurately against gearboxes or mounting plates. The bearings are filled with lifetime grease, so routine relubrication is not required during normal service. Heat generated in the stator is removed through natural convection, eliminating the need for forced-air accessories in most cabinets. This cooling method helps keep the surrounding layout simple where extra airflow hardware is not desired. Rotor position feedback is supplied by an integrated tacho, giving the analog drive continuous velocity information for loop control. An enclosure rating of IP65 protects the windings and terminals from dust ingress and low-pressure water jets.

The motor can be installed at elevations up to 1000 m without derating. All power conductors enter on Side A, so cable routing remains consistent regardless of the selected mounting orientation. This arrangement can simplify cable entry on machines with fixed routing paths. Thermal protection is provided by embedded Thermo Switches that open the control circuit if winding temperature exceeds the permitted limit. A Standard blocking brake is integrated to hold the load when the amplifier is disabled or during power loss.
