Product Description:
The MAC115B-1-GS-4-C/130-B-0/AM164SG 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 converts drive-amplifier current into controlled rotary motion for positioning tables, packaging stations, and other industrial axes. The model combines tacho feedback with incremental or absolute encoder signals so both speed and position can be closed accurately by the host controller. Its mechanical envelope follows the 115 frame format with centering features that simplify installation across the series.
The motor uses winding code GS, which sets the stator resistance and inductance for predictable torque production. A centering diameter of 130 mm guides the housing into machine plates with minimal runout. Its frame is classified as size 115 and length class B, giving a balanced ratio between inertia and continuous power. At a nominal speed of 2000 rpm, the rotor remains within the linear region of the tachogenerator, supporting smooth velocity loops. Ventilation is provided by an external blower rated at AC 230 V, letting the drive maintain rated current during continuous duty.
The unit relies on axial surface cooling, so heat is removed along the outer stator laminations rather than through the shaft bearings. Tachogeneration delivers 3 V/1000 rpm, supplying the controller with a proportional speed signal, while the built-in absolute encoder transmits multi-turn position data. Power conductors are terminated through a connector on side B, which separates high-current lines from feedback cabling on side A. Because a blocking brake is not present, any vertical axis must use external holding devices or dynamic drive torque to secure the load when power is off. The standard tacho quality meets general automation requirements, and the feedback configuration remains compatible with analog and digital drive cards.
