Product Description:

The MAC090C-0-GD-3-C/110-B-0 is a servo motor built by Bosch Rexroth Indramat and delivered as part of the MAC AC Servo Motors series. In automated assembly equipment and machine tools, it converts drive commands from the controller into precise rotary motion, allowing axes to accelerate, decelerate, and hold position in line with process demands. Its basic role is to provide controlled shaft movement for positioning and speed-regulated tasks. It is intended for use with a separate drive system that manages the surrounding motion functions.

The motor uses a centering diameter of 110 mm, which aligns the flange to the mounting surface and helps keep shaft runout within tolerance. Heat produced in the windings is removed by natural convection, so the housing can dissipate heat without an external blower. The motor uses tacho feedback and a second shaft end, allowing a permanent-magnet tachogenerator on the auxiliary shaft to supply an analog speed signal to legacy controllers. Motor power exits through a connector on side B, which can simplify cable routing at the non-drive end of the machine. The unit is a motor for analog drives, so the velocity loop is closed by the external control card rather than by integrated electronics.

The rotor is supplied without a blocking brake, so the installation must use mechanical clamps or continuous drive torque to secure stationary loads. Speed feedback quality is rated as Standard, which is suitable for medium-precision indexing tasks that do not require a low-jitter encoder signal. Electromagnetic behavior is set by winding code GD, which corresponds to the electrical values expected by matched drive modules. The feedback arrangement fits control platforms that use continuous analog speed signals instead of a digital encoder interface. This is useful in retrofit systems that still process tachometer feedback.
