Product Description:

Bosch Rexroth Indramat manufactures the MAC093-1-FS-4C/110-A-3/WA606XX servo motor for analog drives within the MAC AC Servo Motors series. This motor is designed for closed-loop motion axes in industrial automation, delivering rotational power to machinery that requires precise velocity and torque control. The unit includes a blocking brake and axial surface cooling, making it suitable for applications that must hold vertical loads while operating through sustained duty cycles.

The motor provides a continuous stall torque of 28.0 Nm, so it can hold that load indefinitely without exceeding its thermal limits. At its nominal speed of 3000 rpm, the motor supports consistent process timing with a connected analog drive. Supplying that torque at standstill requires a continuous current of 50 A, which is relevant when sizing the drive amplifier and cabling. The integrated blocking brake provides 22 Nm of static torque to resist back-driving forces when the axis is stopped. Transient acceleration demands are covered by a peak pulse current capability of 173 A, allowing rapid starts without overloading the motor. With a torque constant of 0.579 Nm/A, each ampere of phase current produces a predictable amount of shaft torque for controlled motion.

Thermal behavior is characterized by a time constant of 45 min, so the winding mass responds gradually to load changes. The blocking brake operates on 24 V DC, which matches common industrial control voltage. Electrical dynamics are influenced by a winding inductance of 2.9 mH and a phase resistance of 0.175 Ω, supporting smooth current rise while limiting copper losses. An external 230 V blower forces air across the housing’s axial fins, and the 110 mm centering diameter with a 24 mm shaft supports straightforward alignment with drive couplings.
