Product Description:

The MAC090B-0-JD-4HC/110-A-0/WI524LV is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Designed for direct connection to analog drive controllers, it translates armature current into controlled torque and speed so automated lines, printing presses, and machining centers can position axes with repeatable accuracy. The motor fits into modular drive cabinets, allowing the drive amplifier to receive real-time velocity and position data while the output shaft delivers synchronized rotary motion to the load. Its feedback arrangement also allows the external controller to correct load-related speed deviations quickly during acceleration, deceleration, and steady-state operation. This arrangement supports precise motion on feed axes, handling systems, and other equipment that depend on stable servo response.

The unit is supplied without a blocking brake, so holding torque during shutdown must be provided externally. A 110 mm centering diameter aligns the motor flange with the machine interface and helps keep radial runout low. Heat is removed through natural convection, eliminating the need for fans and simplifying the surrounding installation. Three-phase power reaches the stator through a connector on side A, which keeps the main connection path straightforward when cables enter from that direction. During operation, the internal tacho generator produces 1.5 V/1000 rpm, delivering an analog velocity signal that the drive amplifier compares with its command set point for closed-loop speed regulation.

In addition to the tacho output, the motor incorporates an incremental encoder mounted in the standard rear housing, supplying pulse trains for position interpolation and motion tracking. The encoder and generator share standard tacho quality, which supports consistent phase behavior across the usable speed range. Because the design is a motor for analog drives, its feedback format and voltage levels match legacy MAC controllers without the need for conversion modules. The separate feedback channels help the controller distinguish coarse velocity monitoring from finer position evaluation during indexing and synchronized axis movement. This combination allows the motor to provide both speed and position information while remaining compatible with established analog servo systems.
