Product Description:

The MAC093B-0-JS-3-C/130-B-1/S005 servo motor is produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts drive current into controlled torque and speed for machine tools, packaging stations, and handling modules in industrial automation. The model includes a standard blocking brake to secure the load during shutdown, and it is supplied with a second shaft end for external couplings when required by the installation. This operating style supports controlled starts, stops, and steady speed regulation.

Its flange features a centering pilot of 130 mm, allowing precise concentric mounting to gear reducers or coupling hubs while minimizing radial runout. Heat is removed by natural convection, so the housing requires unobstructed ambient airflow during operation. The integrated measurement system uses tacho feedback with a second shaft end; the tacho supplies an analog speed signal, and the extra shaft end can support an external incremental encoder for position loops. Under rated excitation, the rotor reaches 3000 rpm, a speed commonly selected for medium-inertia axes that require rapid positioning. Power conductors enter through a connector on side B, which keeps the cable exit opposite the driven load to reduce bending stress.

The motor’s sensing circuit generates 3 V/1000 rpm of tacho output, enabling drive amplifiers to derive velocity feedback without extra scaling hardware. The JS winding code matches the stator impedance to analog controllers that supply the required current bandwidth. The motor uses size 093 proportions, and the active stack depth corresponds to length B. The B stack length provides additional active magnetic material within this frame size, which supports continuous torque for midsize automation axes.
