Product Description:

The MAC090C-1-GD-4-C/110-A-2/WI521LX/S013 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for use with Indramat analog drive amplifiers, where it converts commanded current into controlled torque and speed for automated equipment such as pick-and-place arms, gantry axes, and feeders. In these installations, the motor forms the electromechanical link between the drive power stage and the mechanical load, supporting precise motion while remaining compatible with legacy analog control loops. This arrangement is useful in systems that still rely on established control hardware but require stable servo response during repeated positioning tasks.

Axial surface cooling is used, and an external fan channels air along the housing fins. The blower operates at AC 230 V to provide steady airflow that limits winding temperature rise during continuous duty. A heavy-duty blocking brake is integrated to lock the shaft whenever the drive is disabled, which helps prevent load drift on vertical or positioning axes. A 110 mm centering diameter seats the flange against gearboxes or machine plates for accurate alignment. The motor uses the GD winding code, which indicates electrical values matched to MAC drive ratings. For motion feedback, a built-in tacho generator works with the encoder so the controller receives both speed-related and position-related signals during operation.

Cable routing is simplified because the power leads exit through a connector on side A, keeping motor and cabinet wiring on one face of the machine. Classified as a motor for analog drives, the unit receives current and velocity commands from legacy drive cards while returning position through an incremental encoder with standard mounting. Speed supervision is provided with standard tacho quality, which supplies a linear voltage proportional to rotor speed for conventional PI speed loops. This feedback arrangement supports stable response at changing speeds and helps the drive maintain consistent regulation during routine axis movement.
