Product Description:

The MAC090C-0-GD-4-C/110-B-0/WI524LV/S001 is manufactured by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It serves as a rotary actuator that receives analog command voltages from a drive controller and produces proportional shaft torque and speed for coordinated motion in industrial automation cells, conveyor stations, and assembly robots. Integrated feedback allows the connected amplifier to monitor motion continuously, which helps maintain stable speed regulation and repeatable positioning during normal operation.

The stator is wound according to the GD code, which identifies the motor's electrical resistance and inductance values so the paired amplifier can supply the proper current. A centering flange with a diameter of 110 mm aligns the housing concentrically to gearboxes or mounting plates, reducing radial runout at the coupling. Heat generated by copper losses is removed through natural convection, so installation must leave open airflow around the fins. Power enters through a connector on side B, which can simplify cable routing when the drive is mounted behind the motor. The motor has no blocking brake, so an external holding device is required if a vertical axis must remain fixed after power is removed.

For velocity feedback, the unit uses tacho feedback with an incremental or absolute encoder, while position control is handled by an incremental encoder with standard mounting. This arrangement supplies both speed-proportional analog information and pulse-based position signals to the connected control system. Being a motor for analog drives allows direct use with legacy amplifier families that regulate current through ±10 V reference signals rather than network-based commands. The encoder signals are provided with standard tacho quality, which is suitable for mid-range indexing and general velocity regulation. This feedback setup supports steady operation on machinery that relies on conventional analog servo control.
