Product Description:

The MAC093B-0-GS-4-C/110-A-2/WI518LV/S005 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive current into precise rotary motion for positioning tasks in automated assembly lines, handling cells, and material processing stations. Its 093 frame size and B length place it in a mid-range torque class, and the 110 mm mounting pilot fits compatible machine interfaces used with MAC motors. This arrangement supports repeatable motion on indexing, transfer, and feed axes where stable response is needed across frequent start and stop cycles.

The unit includes a heavy-duty blocking brake that clamps the shaft when power is removed; this brake withstands up to 14 Nm so suspended loads remain stationary. A flange centering diameter of 110 mm keeps the rotor concentric with attached transmission elements and helps minimize vibration. Internal losses are shed by natural convection, eliminating fans and preserving the sealed housing. At its nominal speed of 4000 rpm, the motor delivers a smooth velocity profile that is monitored by the integral tachogenerator. Standard tacho feedback sends an analog voltage proportional to speed, and the incremental encoder in the standard mounting provides position pulses for the control loop.

The electromagnetic circuit uses the GS winding code, so rated current, back EMF, and resistance are matched to analog drives commonly used with MAC motors. Mechanical power is transferred through a shaft with a DIN 6885 keyway, supporting keyed couplings and synchronous pulleys. Three-phase supply conductors terminate on a connector on side A, keeping power and feedback cables on the same face for simpler routing in tight cabinets. During operation, the tachogenerator delivers 1.5 V/1000 rpm, which is suitable for velocity loops or for a secondary speed signal when incremental feedback is used.
