Product Description:

The MAC090C-0-KD-4-C/110-A-0/WI522LV belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is a motor for analog drives that supplies closed-loop torque and speed control to positioning axes, pick-and-place heads, and other automated machinery. By combining a permanent-magnet rotor with electronic feedback, the unit converts controller commands into precise rotary motion required for industrial automation lines. Because the motor is intended for closed-loop use, the external amplifier can correct speed deviation and torque demand as operating conditions change. This arrangement helps the connected drive maintain stable motion response during repeated start, stop, and positioning cycles.

The winding code KD identifies the electrical resistance and inductance values used with analog drive amplifiers. Under rated excitation, the shaft reaches a nominal speed of 1500 rpm, which supports moderate-speed applications and common gearbox selections. A centering diameter of 110 mm aligns the flange on mounting faces and helps keep the shaft concentric during installation. Heat is removed through natural convection, so the housing requires clear surrounding space for airflow. This cooling method avoids separate fan hardware and keeps the motor layout simple. The motor operates without a blocking brake, so any load that must remain fixed at standstill requires external holding force when power is removed.

Power terminals are routed through a connector on side A, which can simplify cable entry when the drive controller is mounted nearby. Speed feedback to the analog drive is proportional to rotor velocity at 3 V/1000 rpm from the integrated tachogenerator, and position information is delivered by an incremental encoder mounted in the standard feedback location. That feedback arrangement supports steady speed regulation and repeatable axis positioning during routine machine cycles. The electronics also provide tacho feedback support for absolute encoders, which broadens interface compatibility across legacy and newer motion-control systems. The tacho signal is standard quality, and unobstructed ambient airflow around the housing helps maintain consistent thermal behavior during continuous operation.
