Product Description:

The MAC090B-0-JD-4-C/130-B-2/WI518LV/S019 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for integration with analog velocity and current controllers. The unit translates three-phase electrical power into tightly regulated shaft motion that keeps automated cutting heads, pick-and-place arms, and indexing tables synchronized with master control loops. Its servo design supports coordinated motion where rapid correction of speed error is important for process quality.

Cooling is done through natural convection, allowing the motor to dissipate heat without auxiliary blowers and reducing overall noise. A heavy-duty blocking brake locks the rotor when the drive is disabled, which helps hold suspended or overhung loads in place. The mounting pilot measures 130 mm, giving a consistent datum for coupling concentricity and flange alignment. Power conductors enter through a connector on side B, which keeps the connection layout direct and helps separate high-current wiring from low-level feedback cabling. This cable direction can simplify routing when the motor is mounted near guards, slides, or other closely spaced machine elements.

For motion feedback, the motor offers tacho feedback with an incremental or absolute encoder, letting analog drives use either a speed-proportional voltage or digital position tracks. The internal tacho element has standard accuracy, which is suitable for general axis regulation without fine-pitch interpolation. Position sensing is also supported by an incremental encoder with standard mounting, so the housing does not require special mechanical changes for this feedback arrangement. This arrangement is useful on existing analog platforms that rely on familiar feedback handling rather than fieldbus-based motor electronics. Classified as a motor for analog drives, the electrical interface supplies symmetrical sinusoidal back EMF suitable for current-controlled amplifiers that accept ±10 V velocity commands. These feedback and interface choices affect cable length, signal conditioning, and loop bandwidth in the drive system.
