Product Description:

Bosch Rexroth Indramat builds the MAC090C-0-GD-4HC/110-A-0/WI524LV as part of the MAC AC Servo Motors series. This model is supplied as a motor for analog drives used in positioning axes, material handling, and general machine-tool automation. Within such systems, the unit converts drive current into controlled rotary motion that is regulated by an external amplifier and feedback loop, allowing precise speed and torque delivery without the need for mechanical transmission stages. Because the MAC platform is brushless and permanently excited, it offers high dynamic response and continuous duty capability that suits repetitive industrial cycles.

For electrical performance, this motor carries the GD winding code, indicating the resistance and inductance set selected for operation with analog velocity drives. Its centering pilot is machined to 110 mm, allowing accurate coaxial seating against the machine flange and helping maintain runout tolerances. Heat generated in the stator is dissipated by natural convection, so installation must permit free airflow around the housing. The power leads exit through a connector on side A, which simplifies cable routing inside compact cabinets. The motor has no blocking brake, so holding torque must be supplied by the drive or by an external mechanism.

Signal processing is handled through a hybrid feedback package that supports tacho feedback with an incremental or absolute encoder, letting the external controller use speed or position regulation as required. The main position channel is delivered by an incremental encoder with standard mounting, ensuring straightforward alignment with Indramat amplifier scaling factors. For velocity loops, the built-in tacho generator produces 1.5 V/1000 rpm, giving a linear analog voltage that the drive card uses for rapid speed correction. The tacho output smoothness is Standard, which suits general motion tasks where ripple within normal limits does not affect machining accuracy.
