Product Description:

The MAC090B-0-JD-1-B/130-B-0-I01000/S003 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, this motor converts electrical energy into controlled rotary motion for positioning, conveyor, and tooling axes within industrial automation cells. It works with an external drive controller that regulates phase current so commanded motion profiles are tracked with minimal error. This arrangement makes the motor suitable for applications that need repeatable speed control and accurate shaft positioning during continuous machine cycles.

During operation, the unit reaches a nominal speed of 3000 rpm, which suits general industrial motion tasks that require a broad working speed range. Under locked-rotor conditions, it can sustain a stall torque of 6.7 Nm while drawing a stall current of 18.2 A. Short acceleration bursts are supported by a peak pulse current of 137 A, which helps the motor respond quickly during indexing moves. The electromagnetic conversion is characterized by a torque constant of 0.41 Nm/A, so output torque changes in proportion to commanded current. Copper loss and thermal rise are also affected by the winding resistance, which should be considered when the drive is tuned for stable response.

Mechanical integration is aided by a centering diameter of 130 mm and a shaft ground to Ø24 k6, and a shaft seal is fitted at the output end to help limit ingress. The motor mass is 18 kg, and the rotor inertia supports predictable response when matched to the driven load. The enclosure has an IP65 rating, and cooling is handled by natural convection, so no external blower is required. Feedback is provided by an incremental encoder, and power is routed through a connector on side B for straightforward cable routing. Because the motor does not include a blocking brake, static holding must be provided externally. The winding inductance is 2.0 mH, and the thermal time constant is 60 min.
