Product Description:

The MAC090A-0-RD-3-C/110-B-1 is a rotary AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor component matched to analog servo amplifiers, it translates ±10 V command signals into controlled torque and velocity for automated production axes, indexing tables, or material-handling gantries. The construction supports direct coupling to mid-range loads so that motion systems can achieve repeatable positioning without intermediary gear trains. This arrangement suits positioning tasks that require smooth speed control and stable response in general automation equipment.

Mounting is guided by a 110 mm centering diameter that aligns the stator housing to standard flange patterns while maintaining concentricity between the motor and the driven shaft. Thermal energy is removed by natural convection, allowing the unit to operate without auxiliary blowers or liquid circuits when cabinet airflow is limited. A standard blocking brake is integrated to hold the shaft at standstill after power loss, which supports vertical-axis holding requirements. All three-phase leads exit through a connector on side B, keeping the cable bundle away from front-side mechanical interfaces. Because it is a motor for analog drives, its electrical characteristics match current-controlled amplifiers that expect a proportional speed signal.

Velocity feedback is supplied by internal tacho feedback, which provides a speed signal for closed-loop analog regulation. The inclusion of a second shaft end allows mounting of an external incremental encoder or handwheel without changing the primary load connection. The motor uses standard tacho quality, which provides a linear voltage proportional to speed and supports typical ripple limits in analog control loops. The additional shaft access also supports auxiliary devices in machines that separate feedback hardware from the main load coupling.
