Product Description:

The MAC093B-0-OS-3-C/110-A-1 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. The unit is intended for analog drives and converts ±10 V speed commands into controlled shaft rotation for regulated motion. In automated assembly lines, it provides repeatable torque and position accuracy for feeders, small presses, and gantry axes. A standard housing with metric mounting interfaces supports installation in existing machine frames while keeping cable routing straightforward.

A centering diameter of 110 mm forms the mechanical interface and helps keep the motor aligned with the driven load. Heat is removed through natural convection, so no external blower or coolant lines are required when the shaft runs at its nominal speed of 2000 min⁻¹. Power enters through a connector on side A, which can simplify cable routing along the machine frame. Velocity feedback to the drive is generated by the internal tacho generator, which delivers 3 V/1000 min⁻¹. This proportional signal allows the analog controller to close the speed loop with minimal signal processing, and the tacho quality is standard for applications that do not require tighter-than-normal manufacturing tolerance.

The motor has frame designation 093, which corresponds to the stator cross-section used for this model. Length code B gives the motor a longer active stack to support higher continuous torque than shorter versions in the same frame size. Winding code OS indicates the resistance and inductance combination used by the motor for compatible drive current levels. The feedback package includes tacho feedback and a second shaft end, so an auxiliary encoder or mechanical load can use the rear stub without additional couplings. A blocking brake is supplied as standard and holds the shaft when the analog drive is disabled.
