Product Description:

The MAC071B-0-FS-4-C/095-B-0/WI1520LV/S001 is supplied by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it delivers regulated rotary motion to machine axes, indexing tables, and other positioning elements used in automated production cells. Natural-convection cooling, a 95 mm centering diameter, and an IP-rated housing allow the unit to mount directly on equipment frames while exchanging heat only through its surface.

This model can produce a continuous stall torque of 4.4 Nm while drawing a continuous stall current of 5.0 A. Under rated conditions it reaches a nominal speed of 2000 rpm, a value matched to mid-range feed or spindle tasks that do not require additional fans. The magnetic design yields a torque constant of 0.880 Nm/A, so drive electronics can estimate output torque from measured phase current. An ingress rating of IP 65 seals the stator interior against dust and low-pressure water jets, supporting installation in machining, packaging, or material-handling environments where airborne contaminants are present. The rotor inertia is 9.9 × 10⁻⁴ kg·m², and the thermal time constant is 45 minutes, indicating moderate responsiveness and a gradual temperature rise during cyclic loads.

For rapid accelerations the winding can accept a maximum pulse current of 25 A, giving headroom for short torque peaks without breaching thermal limits. Electrical losses are governed by a winding resistance of 2.7 Ω at 20 °C and an inductance of 22 mH, parameters that influence drive bandwidth and filter requirements. Overall mass is 8.8 kg, light enough for gantry or robotic joints yet heavy enough to damp vibration. Incremental encoder feedback with standard mounting supplies velocity and position signals, while allowable ambient temperature tops out at 45 °C and storage limits span –20 °C to 80 °C.
