Product Description:
The MAC090B-0-JD-1-B/110-A-0-100625 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drives, it converts commanded current into controlled torque and speed for positioning tables, conveyors, and similar motion axes in industrial automation environments. Its closed-loop feedback arrangement helps the paired drive monitor shaft movement and correct speed deviations during operation, which supports stable motion in both indexing and continuous-running tasks.
The motor can sustain a continuous standstill torque of 6.7 Nm, allowing it to hold a load steadily without rotation when required. Its nominal operating speed is 3000 rpm, which is the rated synchronous velocity under full load. A continuous standstill current of 18.2 A is needed to generate the rated holding torque, and this current flows through a stator winding resistance of 0.38 Ω, which indicates the basic copper loss during constant-torque operation. The winding inductance of 2.0 mH influences how quickly current can rise and how much ripple appears under pulse-width-modulated drive signals. Heat is removed by natural convection, and the power connector is located on side A for straightforward cabling in compact machine layouts.
During acceleration or shock loading, the drive may send a peak pulse current of 137 A, giving the machine headroom for rapid dynamic moves. A rotor inertia of 0.0036 kg·m² balances responsiveness with mechanical stability, while the thermal time constant of 60 min shows that internal temperatures change gradually during extended operation. The enclosure meets the IP65 protection class, so dust and low-pressure water jets will not impair service. Additional features include a 110 mm centering diameter for flange alignment, a 24 mm shaft diameter for coupling selection, incremental encoder feedback for speed and position reporting, and permitted operation at installation altitudes up to 1000 m.
