Product Description:

The MAC093B-0-JS-3-C/110-B-1/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a rotary actuator for analog drive systems, it converts proportional current from a controller into tightly regulated torque and speed. This operation allows automated equipment to index, feed, or follow process commands with high repeatability on production lines.

The motor uses a centering pilot of 110 mm, allowing direct flange mounting to gearboxes that share this registration diameter. Its stator and rotor assembly has a nominal speed of 3000 rpm, providing a fixed operating point for selecting gear ratios and configuring feedback scaling. A built-in DC tachogenerator delivers 3 V/1000 rpm, providing an analog velocity signal compatible with legacy servo amplifiers. The tachogenerator uses the standard quality level for this motor family. Thermal energy is dissipated through natural convection, removing the need for an external blower when sufficient airflow is available. The electromagnetic circuit uses winding code JS, which indicates the phase resistance and inductance used to tune current regulators. Frame code 093 and motor length B establish the magnetic stack height and overall shaft extension, balancing rotor inertia for moderate loads.

An integrated standard blocking brake locks the shaft when power is removed, preventing drift on vertical or indexing axes. The encoder side has tachofeedback and a second shaft end, allowing the free end to connect to an additional encoder or manual handwheel without interfering with the built-in tachogenerator. Power conductors reach the windings through a connector on side B, allowing the cable to be disconnected without disturbing the flange bolts. Classified as a motor for analog drives, the unit supports current-mode amplifiers that use the tachogenerator signal for closed-loop speed regulation. The additional shaft connection also gives the machine layout flexibility when a secondary feedback device or mechanical accessory is required.
