Product Description:

The MAC093C-0-FS-3-C/110-B-0/S001 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analogue drives, it is used to supply regulated torque and speed to machinery axes in industrial automation cells, packaging stations, and material-handling gantries. Natural convection cooling allows the housing to shed heat without auxiliary fans, while a connector on side B carries power into the stator windings. A 110 mm centering diameter aligns the flange during installation and the second shaft end supports the integrated tacho generator that provides velocity feedback.

The motor can sustain a continuous stall torque of 19.5 Nm; this is the torque available when the rotor is locked and the windings are at rated temperature. To deliver that torque, the windings draw a continuous stall current of 35 A, so drive sizing must account for that steady current demand. At its nominal speed of 3000 min⁻¹ the rotor completes fifty revolutions per second, a common target for servo positioning applications that blend rapid moves with fine control. A torque constant of 0.579 Nm/A links phase current to produced torque, enabling the controller to convert current loop output directly into mechanical force commands. The winding resistance measured at 20 °C is 0.175 Ω, which affects copper losses and the drive’s ability to regulate current precisely during dynamic transitions.

For transient moves such as indexing or sudden load changes, the windings can accept a peak pulse current of 173 A without exceeding thermal limits. The housing carries a protection rating of IP65, so dust ingress and low-pressure water jets will not reach internal components. A thermal time constant of 50 min indicates how slowly the winding temperature rises, allowing short overloads before steady-state heat equilibrium is reached. Electrical dynamics are influenced by a winding inductance of 2.9 mH, which shapes current rise times and assists the drive in filtering switching ripple while preserving responsive torque control.
