Product Description:

The MAC090C-2-GD4-C/110-A-0/WI520LX is a three-phase servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts command voltages from positioning controllers into regulated rotary motion for machinery axes, conveyors, and forming equipment. Axial surface cooling is provided by an external 115 V AC blower that moves air across the housing to keep the stator windings within their thermal limits. An incremental encoder and tacho feedback supply speed and position data to the drive amplifier, while a 110 mm centering diameter helps align the flange and the power connection is located on side A. This arrangement allows the motor to operate in closed-loop systems that use external analog amplification for speed and position control.

A continuous phase current of 41.3 A allows the motor to deliver a steady mechanical output of 16.0 Nm without exceeding the permissible temperature rise. During rated operation, the shaft turns at 3000 rpm, balancing torque output with operating speed for general industrial motion tasks. The motor produces about 0.43 Nm/A, showing how effectively drive current is converted into torque by the permanent-magnet design and winding layout. For rapid acceleration, the drive can supply short pulses up to 196 A, and the auxiliary tacho generator produces 3 V per 1000 rpm for velocity-loop feedback.

The rotor inertia of 0.0053 kg·m² supports stable servo response when the motor is paired with mid-mass loads. A thermal time constant of 45 min means absorbed heat dissipates gradually during continuous duty, giving the system some tolerance for brief overloads. The winding inductance of 1.5 mH helps filter current ripple, and the winding resistance of 0.24 Ω influences copper losses and the drive's voltage demand. These electrical values affect current response, heat buildup, and acceleration behavior under changing loads. The GD winding code and axial airflow shape the motor's electrical and thermal behavior during typical industrial operation.
