MAC071B-0-FS-4-C/095-A-0/WA612XX

The MAC071B-0-FS-4-C/095-A-0/WA612XX from Bosch Rexroth Indramat belongs to the MAC AC Servo Motors series and delivers a 2000 rpm top speed with a continuous torque of 4.4 Nm at standstill. This AC Servo Motor features a Motor Size 71 frame and a compact Motor Length B profile that streamline integration into precision machinery. Its AC Servo Motor type MAC construction ensures consistent performance across packaging, manufacturing, and automated assembly applications. A built-in B encoder provides high-resolution feedback for closed-loop control and positioning accuracy.

Electrically, the unit draws a nominal continuous standstill current of 5 A and tolerates a maximum peak pulse current of 25 A for short durations without damage. The windings exhibit a torque constant of 0.880 Nm/A, a winding inductance of 22 mH, and a resistance of 2.7 Ω at 20 °C, optimizing both responsiveness and energy efficiency. A thermal time constant of 45 minutes allows predictable thermal behavior under varying load, while the natural convection Cooling Type simplifies installation by eliminating the need for auxiliary fans.

Mechanically, the Power Connection Side A interface and the Not Equipped Blocking Brake option reduce installation steps and maintenance points. The enclosure meets IP65 protection standards to withstand dust ingress and water jets, and operates reliably up to a maximum ambient temperature of 45 °C. With overall dimensions of 435 mm x 118 mm and a mass of 8.8 kg, this motor balances compactness and robustness for demanding industrial environments.
