Product Description:

The Bosch Rexroth Indramat MAC090B-0-PD-4-C-110-A-1-WI520LV is an AC servo motor belonging to the MAC AC Servo Motors series. In automated production lines, it couples with a drive amplifier to transform controlled stator currents into repeatable shaft motion, supplying closed-loop speed and position control for indexing tables, handling units, and processing spindles. The motor operates as the electromechanical element within Indramat legacy drive systems where rapid response and continuous duty are required.

The motor has a centering diameter of 110 mm, allowing the housing to seat precisely into machinery frames or gearboxes without shims. Heat is removed by natural convection, so no blower or liquid circuit is required and installation can stay compact as long as ambient air can circulate freely. At a nominal speed of 1500 rpm, the magnetic circuit and copper layout reach rated torque while remaining within the continuous-duty range. Power is routed through a single plug-in connector on side A, which keeps the cable path clear when the motor is mounted with the shaft facing forward. The stator carries a PD winding, which uses electrical values suited to Indramat MAC drive modules.

Speed feedback for the control loop comes from a tachogenerator that produces 3 V/1000 rpm, supplemented by an incremental encoder mounted on the shaft end for digital position capture. Together, these devices provide speed and position signals for closed-loop operation in legacy motion systems. As a motor for analog drives, the unit presents a voltage interface that pairs with legacy current-loop amplifiers still used on many processing lines. A standard blocking brake is integrated to hold the load when power is removed, helping prevent drift on vertical axes. This arrangement supports stable holding at standstill without requiring a separate external locking device in many applications.
