Product Description:

The MAC090C-1-GD-4-C/110-A-2/WI525LV/S013 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for integration with analog drive controllers, the motor supplies regulated torque and speed to automated machinery that requires repeatable rotary motion for conveyors, pick-and-place heads, or indexing tables. Its cooling and feedback options allow it to support continuous motion and stable speed regulation in general automation applications.

The stator uses winding code GD, which sets the electrical resistance and inductance so the drive can deliver rated current without saturation. Heat generated in the windings is removed through axial surface cooling, and an external blower operating at AC 230 V moves air along the housing ribs to maintain permissible temperatures. A centering shoulder measuring 110 mm locates the motor precisely on the machine frame, which helps reduce radial runout during installation. Power conductors are routed through a connector on side A, which can simplify cable layouts when the motor is mounted with the shaft facing the work area and the wiring exit turned toward the control cabinet.

A heavy-duty blocking brake is fitted to lock the shaft during power-off conditions or emergency stops, allowing vertical axes or suspended loads to remain stationary without external clamps. For velocity feedback, the housing accommodates tacho feedback, incremental encoder, or absolute encoder devices, while position loops can rely on an incremental encoder with standard mounting. Classified as a motor for analog drives, the device delivers speed signals directly to legacy amplifiers that regulate armature voltage rather than exchange digital packets. Its tacho quality is specified as standard, providing the accuracy level customary for general-purpose motion axes.
