Product Description:
The MAC090B-0-PD-2-C/110 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is built for analog drive amplifiers, where it generates controlled torque and speed for industrial axes that require precise, feedback-regulated motion. Typical installation points include packaging stations, small machining centers, and material-feed units that rely on continuous duty cycles without supplemental cooling fans. The motor is suited to applications where the amplifier closes the speed loop and where predictable response is more important than very high peak speed. That makes it appropriate for conveyor indexing, feed control, and other repeated motion tasks.
This motor seats against machine frames with a centering diameter of 110 mm, allowing accurate shaft alignment during assembly. Heat is removed through natural convection, so cabinet airflow calculations do not need to account for an internal blower. Rotor velocity is monitored by an integral tachogenerator, and the housing therefore includes tacho feedback to create an analog speed signal for the drive. Under rated electrical excitation, the shaft turns at 1500 rpm, giving a fixed base speed for gear-ratio selection. Winding code PD indicates the electrical values expected by a compatible analog amplifier.
Tachogenerator linearity is classified as Standard, which maintains proportionality between actual shaft speed and the feedback voltage in general-purpose motion loops. At nominal speed, the tachogenerator produces 3 V/1000 rpm, and this output can be read directly by the drive for closed-loop speed control. Because it is specified as a motor for analog drives, its connector layout and signal levels follow the conventions used by legacy MAC drive cards. The feedback arrangement also helps the amplifier correct minor load changes quickly, so commanded velocity remains steady during normal process variations. This arrangement supports stable operation during extended production runs and keeps the interface compatible with established analog control hardware.
