Product Description:

The MAC093B-0-GS-3-C/110-B-2/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts voltage commands from legacy controllers into controlled mechanical motion for positioning tasks in industrial automation. The unit’s 093 frame size permits moderate power density, and a heavy-duty blocking brake is fitted so vertical or suspended loads remain fixed when power is removed during normal stops or unexpected outages. That arrangement suits packaging, transfer, and lift axes that must resume controlled motion after a stop without unwanted shaft movement.

The motor reaches a nominal speed of 4000 rpm, which is its continuous operating velocity under rated voltage and load. Holding capability is provided by a blocking brake that can withstand 14 Nm of static torque, preventing the load from backdriving the shaft during idle states. A centering diameter of 110 mm aligns the housing precisely on mating flanges, reducing radial runout in coupled mechanisms. The centering fit also helps maintain consistent coupling alignment over long operating periods. Heat generated by the winding is dissipated through natural convection, so no external fan or liquid circuit is required. For speed monitoring, the built-in tacho generator delivers 1.5 V/1000 rpm, giving analog feedback proportional to shaft velocity for closed-loop regulation by the connected drive.

The GS winding code identifies the stator’s resistance and inductance so matching drive electronics can supply the correct current without saturation. Power is routed through a connector on side B, allowing cable runs to stay inside the machine envelope and simplifying routing near adjacent components. The motor uses tacho feedback and a second shaft end, which allows speed monitoring and supports the attachment of an additional encoder or auxiliary mechanical element. This layout is useful where cable exit direction and accessory mounting space are limited. The motor has length B, balancing inertia against the available installation depth, and the standard tacho quality helps maintain repeatable speed signals during operation.
