Product Description:

The MAC090C-0-KD-1B/110-A-0-I01250 is an AC servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. Built for analog drive systems, it converts command voltages from a servo amplifier into rotary motion for indexing tables, pick-and-place modules, and similar stations on automated lines. Its compact frame mounts directly to gear stages or belt transmissions inside protected machinery. This arrangement supports controlled speed changes and repeatable axis movement in enclosed automation equipment.

Its nominal operating speed is 1500 rpm, which is the rated shaft speed during normal operation. At standstill, the motor can exert 10.4 Nm while drawing 17.0 A. The torque constant is 0.68 Nm/A, so analog current commands produce predictable torque, and the windings can accept short bursts up to 125 A before current limiting intervenes. Winding code KD identifies the electrical layout, while the 0.60 Ω resistance and 3.6 mH inductance affect copper loss and current rise time. A minimum power-lead cross section of 1.5 mm² is required to keep cable heating within acceptable limits during continuous and transient duty.

The mechanical interface uses an output shaft diameter of 30 mm and a 110 mm centering diameter for accurate alignment with couplings and pulleys. An INS 108/02 power connector works with the housing to maintain an IP65 seal against dust and water jets. Heat is removed by natural convection, and the thermal time constant of 60 min means the housing warms gradually during continuous duty. Incremental encoder feedback returns position data to the analog drive for speed and position correction during motion. Because the motor does not include a blocking brake, external locking or drive-applied holding torque is needed when the load must remain fixed at standstill.
