Product Description:

The MAC093B-0-GS-4-C/110-A-3/WI522LV/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it translates voltage-controlled command signals into regulated torque and speed for machinery such as pick-and-place stations, feeders, or forming axes. The unit offers a mid-size footprint that fits many machine beds while still accommodating the components required for the brake, feedback devices, and power connections.

An integrated extra heavy-duty blocking brake provides mechanical load securing, and its stall capacity of 22 Nm helps prevent vertical axes from drifting when power is removed. Accurate mounting is assisted by a 110 mm centering diameter that aligns the flange to the machine plate. Shaft torque is transmitted through a DIN 6885 keyway, so standard keyed couplings can be used without additional machining. Its frame pairs with a B-length stator to balance inertia against rated output. Under nominal excitation, the motor reaches a synchronous speed of 4000 rpm, supporting rapid positioning cycles while keeping thermal rise within the limits of its passive cooling design.

Thermal management relies on natural convection, eliminating blowers and reducing maintenance points. Mains power enters through a connector on side A, which simplifies cable routing inside compact cabinets. For velocity loops, the motor integrates a tacho generator that produces 1.5 V/1000 rpm, and its signal quality is classified as standard. Position data is delivered by an incremental encoder with standard mounting, and the combined tachofeedback interface also accepts an absolute encoder when higher resolution is required. The armature uses winding designation GS, giving electrical characteristics matched to MAC amplifiers.
