MAC071B-0-FS-4-C/095-A-1/WI531LX

The MAC071B-0-FS-4-C/095-A-1/WI531LX, Bosch Rexroth Indramat, MAC AC Servo Motors series introduces a high-performance permanent magnet AC servo motor engineered for demanding automation tasks. The robust housing features an IP65 protection class and weighs only 8.8 kg, balancing durability with ease of installation. Its Side A power connection simplifies cabinet wiring layouts, while the integrated Incremental Encoder with Standard Mounting provides precise position feedback. A Standard blocking brake rated at 3 Nm ensures reliable holding torque during power-off conditions.

This motor delivers a nominal speed of 2000 min⁻¹ and maintains a continuous torque of 4.4 Nm with a standstill current (Idn) of 5 A. Internally, the rotor moment of inertia (Jm) of 9.9×10⁻⁴ kg·m² and a torque constant (Km) of 0.880 Nm/A at 20 °C enable agile acceleration. The stator winding inductance (La) of 22 mH and resistance (Ra) of 2.7 Ω at 20 °C define the motor’s electrical dynamics, while a thermal time constant (Tth) of 45 min supports extended duty cycles. Peak pulse currents up to 25 A accommodate transient torque demands without oversizing the drive inverter.

Designed for seamless integration, the MAC071B motor is available in Motor Size 71 with Motor Length B dimensions and mounts via face (B14) or flange (B05) interfaces. Natural convection cooling preserves a compact footprint without auxiliary fans, and operation is rated from 0 °C to +45 °C at elevations up to 1000 m. Engineers benefit from the built-in encoder and brake, reducing auxiliary component costs and streamlining assembly. Its combination of precise feedback, robust braking, and standardized connections makes this MAC permanent magnet motor ideal for robotics, packaging machinery, and high-duty-cycle automation systems.
