Product Description:

The MAC090A-0-RD-4-C/110-B-0/WI518LV is an AC servo motor developed by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, the unit transforms voltage-based commands into controlled rotary motion so industrial machinery can position loads with repeatable accuracy and short cycle times. When used with a matching amplifier, it provides closed-loop torque and speed control without adding mechanical transmissions. This operating arrangement helps the axis respond quickly to load changes while maintaining smooth motion during indexing and feed movements.

Installation accuracy is helped by a centering flange that measures 110 mm, allowing the housing to seat squarely against gearboxes or machine frames. Thermal energy leaves the stator through natural convection, eliminating the need for fans or liquid circuits and simplifying cabinet layouts. Power conductors terminate on a connector on side B, keeping cable routing clear of the shaft end. The motor has no blocking brake, so load holding during a power-off state must rely on the drive or an external clamp. Rotor position and velocity are detected by an incremental encoder mounted in the encoder section, supplying the feedback that analog regulators require for proportional control.

Frame size 090 and motor length A indicate a compact housing format, while winding code RD identifies the electrical design used in this version. The feedback device fits in a standard encoder pocket, which helps preserve the same basic mechanical arrangement when a different signal source is required. Because the motor is intended for voltage-controlled amplifiers, its response suits indexers, pick-and-place axes, and material-handling equipment where stable speed feedback and repeatable motion are important. The encoder section can support alternate feedback arrangements within the same general mounting concept when the application calls for a different control approach.
