Product Description:
The MAC090C-1-GD-4-C/110-A-1/WI525LV belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is a permanent-magnet synchronous motor intended for use with analog servo drives where precise speed and torque control are required in automated machinery. Within an installation, the motor converts electrical energy from the drive into mechanical rotation for positioning tasks or continuous motion in industrial automation cells. Its operating concept suits applications that need stable response during repeated starts, stops, and controlled speed changes.
This model uses axial surface cooling, so external airflow moves across the housing to remove heat generated by the stator windings. A separate blower rated at AC 230 V supplies that airflow, allowing the motor to remain within its thermal limits during extended duty cycles. The flange carries a centering pilot of 110 mm, which aligns the frame concentrically on the mounting surface and helps reduce shaft offset during installation. A standard blocking brake is integrated to hold the load when drive power is removed, preventing unintended motion on vertical or indexing axes. The GD winding sets the electrical characteristics used with Indramat analog controllers for this frame size.
Position and velocity feedback are provided through a sensor package that offers incremental or absolute encoder signals, enabling the drive to close control loops without external transducers. Power leads exit through a connector on side A, which simplifies cable routing along machine frames that use a single service corridor. Speed estimation for the control loop is aided by a tacho generator built to standard tacho quality, contributing repeatable analog voltage proportional to shaft speed. Classified as a motor for analog drives, this unit works with legacy Indramat drive racks and supports closed-loop servo operation. The combined feedback arrangement helps the drive maintain stable motion during acceleration, steady running, and position correction.
