Product Description:
The MAC115B-1-GS-4-C/130-B-1/WA608XX is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it delivers controlled torque and speed in automated material-handling and process equipment where coordinated multi-axis motion is required. Its layout supports repeatable starts, stops, and speed changes during normal machine cycles. The motor is suited to positioning and speed-controlled applications that need stable motion across changing loads.
This motor integrates a blocking brake rated at 45 Nm to hold the load when power is removed. An external blower powered by AC 230 V provides axial surface cooling, allowing continuous operation at the nominal speed of 2000 rpm without excessive winding temperature rise. Accurate mechanical alignment during installation is supported by a 130 mm centering diameter. The product is intended for analog drives, so velocity references enter as continuous voltages instead of digital words. Motor length B offers moderate rotor inertia suited to general-purpose machinery. The internal tachogenerator is the standard quality version, and either tacho feedback or an absolute encoder can be fitted depending on the feedback configuration.
Motor dynamics are monitored through a tacho generator that outputs 3 V/1000 rpm, supporting fast velocity loops in classic analog control systems. The housing matches motor size 115, while the B-length frame keeps the installation depth compact. Power enters through a connector on side B, simplifying cable routing when the motor sits close to other components. The motor uses winding code GS, which aligns phase resistance and inductance with the intended amplifier range. An attachment set for position feedback devices is included, making it possible to upgrade from incremental to absolute sensing without mechanical changes.
