Product Description:

The MAC090C-0-KD-4-C/130-B-1/WI511LV/S011 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a permanent-magnet servo unit intended for closed-loop motion tasks in automated machinery that uses legacy servo control hardware. By converting amplifier commands into controlled torque and position, the motor supports precise axis control in packaging lines, material-handling gantries, and similar equipment. Its compact servo design also suits machines that need repeatable motion without a separate cooling system.

This model uses a mechanical frame with a centering diameter of 130 mm, allowing straightforward flange mounting to gearboxes or direct-drive arrangements. Heat is removed through natural convection, so no external blower or liquid circuit is required. The nominal shaft speed is 1500 rpm, which supports steady operation in moderate-speed positioning and feed applications. Power conductors connect through a connector on side B, keeping the opposite face clear for associated signal routing. Electrical characteristics are set by the KD winding, whose resistance and inductance values match compatible Indramat controllers for proper current regulation.

Rotary position is monitored by an incremental encoder mounted in the standard feedback location, and it works with the installed tachogenerator so both angle and velocity information are available to the drive. The tachogenerator produces 3 V/1000 rpm, providing a linear speed signal across the operating range. A factory-installed blocking brake holds the shaft when power is removed, which helps prevent load drift on vertical or suspended axes. The unit is a motor for analog drives, so its combination of tacho feedback and encoder signals fits legacy drive racks that rely on voltage-based control rather than digital fieldbus communication.
