Product Description:

The MAC090C-0-GD-3-C/110-A-2/S023 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It converts drive controller commands into controlled shaft rotation for indexing tables, pick-and-place heads, and similar motion axes in automated assembly and packaging lines. The motor is intended for mid-range duties where repeatable acceleration, predictable stopping, and stable running speed are needed during frequent cycle changes. Its compact housing allows it to fit machine layouts that use planetary gearboxes or belt stages without requiring a large mounting footprint.

A mechanically integrated heavy-duty blocking brake locks the shaft whenever supply power is removed, which helps prevent back-driving on vertical or overhung loads. The motor seats against pilot surfaces with a centering diameter of 110 mm, supporting accurate alignment to flanges or gearboxes. Heat is removed by natural convection, so the surrounding air must remain within allowable limits during operation. The motor includes tacho feedback and a second shaft end, allowing speed feedback to the drive and mechanical coupling to an external encoder or handwheel. Incoming three-phase power reaches the stator windings through a connector on side A, which can simplify cable routing around nearby machine components.

Electrical behavior is set by the GD winding code, which establishes the current-related characteristics expected by compatible analog amplifiers. Low-speed operation uses a standard tacho quality signal that is suitable for velocity loops where very high digital resolution is not required. The unit is classified as a motor for analog drives, so it works with amplifier families that regulate current and speed through continuous control signals rather than digital communication. This arrangement suits established machine platforms that still use analog servo control for coordinated axis motion.
