Product Description:

The MAC090C-0-KD-2-C/110-B-0 is an AC servo motor manufactured by Bosch Rexroth Indramat and placed within the MAC AC Servo Motors series. Designed for analog velocity and current loops, this motor drives shafts and machine elements in automated assembly cells, conveyors, and material-handling axes. It converts an analog drive command from the controller into controlled mechanical rotation, supplying the torque and speed response needed for coordinated multi-axis movement. This type of motor is suited to applications that depend on smooth speed regulation and repeatable shaft motion over varying loads.

A centering diameter of 110 mm sets the pilot fit for flange mounting and keeps the stator concentric with the driven equipment. Heat generated by copper losses is removed through natural convection, so no external blower or liquid circuit is required. This cooling method helps keep the machine layout simple where added airflow hardware is not desired. Under rated conditions, the shaft reaches 1500 rpm, a speed suited to gear stages and feed screws used in general automation. The electromagnetic package uses winding code KD, which corresponds to resistance and inductance values matched to the analog amplifier range. For velocity feedback, the integral tacho generator outputs 3 V/1000 rpm, giving the drive a linear voltage signal that follows actual shaft speed.

The motor is cabled through a connector on side B, allowing service access from the rear of a cabinet or gantry beam while keeping the opposite side clear for mechanical coupling. Rear cable entry can also simplify routing where couplings, pulleys, or gearheads occupy the front working area. It is supplied without a blocking brake, so inertial loads must be held by drive torque or an external clamp when power is removed. The tachometer section is built to standard tacho quality, and the control loop uses tacho feedback for stable speed regulation during continuous operation.
