Product Description:

The MAC090C-0-GD-3-C/110-B-2/S013 is a servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Built for analog motion loops, it translates proportional voltage commands from legacy drive cards into controlled rotation for machine tools, packaging stations, and material handlers. By combining a permanent-magnet rotor with incremental tachometer feedback, the device supplies precise torque and speed so that axis regulators can perform closed-loop positioning without high-bandwidth digital buses.

The motor’s mechanical interface begins with a centering flange of 110 mm, allowing repeatable alignment when it is doweled into a mounting plate. Thermal management depends solely on natural convection, so ambient airflow must be adequate because no fan or liquid circuit is present. Feedback hardware is supplied with tacho feedback and a second shaft end, giving the control cabinet a velocity signal while leaving room for a belt pulley or handwheel on the auxiliary stub. Power conductors route through a keyed connector on side B, keeping cables clear of the opposite shaft side and matching standard Indramat pin assignments. Electrical constants are tuned so the unit serves as a motor for analog drives, accepting a ±10 V reference rather than a serial fieldbus command.

For static holding duties, a heavy-duty blocking brake is built into the non-drive end; once de-energized, it locks the rotor so vertical or rotary tables remain fixed during power loss. The speed signal line uses standard tacho quality, providing consistent voltage per revolution for straightforward gain calculations and stable speed regulation. Magnetic and thermal behavior aligns with winding code GD, which indicates the wire gauge, turns count, and nominal current used for this frame size. This arrangement supports the current and voltage characteristics expected by compatible analog amplifiers.
