Product Description:

The MAC090B-0-JD-4-C/110-B-1/W1524LX is an AC servo motor built by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for closed-loop motion axes that rely on analog velocity or torque commands, the unit converts electrical energy into controlled rotary motion for positioning tables, gantries, and processing equipment in automated lines. Its design supports repeatable axis movement in systems that need steady response during frequent starts, stops, speed changes, and direction reversals under normal production duty.

The flange on this motor has a centering register of 110 mm, allowing accurate alignment with gearboxes or machine frames. Heat is shed through natural convection, so no external blower or liquid circuit is required when the housing operates within its rated ambient range. Power conductors terminate through a connector on side B, which keeps high-current wiring away from feedback cabling on the opposite face. Rotor speed information is derived by a tacho feedback device, enabling fine velocity regulation without relying solely on drive electronics. A standard blocking brake holds the shaft when power is removed, helping prevent load drift on vertical or overhung axes.

The unit is identified as a motor for analog drives, so its internal windings and sensor signals are scaled for ±10 V command interfaces typically found in legacy drive racks. Position verification can be upgraded with an incremental or absolute encoder that fits in the same mechanical envelope as the tacho, allowing migration to more modern control loops without changing the basic motor footprint. The standard tacho quality rating indicates permissible ripple in the generated velocity signal, which is suitable for most general-purpose applications that do not demand extremely fine positioning accuracy. It shares mounting patterns and electrical pinouts with other frame sizes, which helps it fit established machine layouts.
