MAC AC Servo Motors
The Bosch Rexroth Indramat MAC041A-0-FS-4-E/050-B-0/WI671LV/S001 is a precision AC servo motor within the MAC AC Servo Motors series by Bosch Rexroth Indramat, designed for demanding industrial automation tasks. Featuring a nominal motor speed of 2000 min-1 and a continuous torque at standstill of 9.2 Nm, this unit delivers reliable static torque for holding and positioning applications. Its robust protection category IP65 ensures resistance to dust and water ingress, making it ideal for harsh factory environments.
This servo motor is engineered for performance and efficiency, with a continuous current at standstill of 11 A and a torque constant at 20 °C of 0.875 Nm/A, ensuring accurate torque generation under varying loads. The windings resistance at 20 °C of 1.313 Ohm and windings inductance of 16.0 mH support consistent current regulation and low electrical noise. For rapid acceleration and deceleration, the motor handles a maximum peak of pulse current up to 54 A. Integrated tachogenerator feedback with a voltage constant of 0.0143 Vs/rad provides precise speed measurement for closed-loop control systems.
Durability and operational flexibility are enhanced by a thermal time constant of 50 min, allowing extended duty cycles before reaching thermal limits. With a rotor moment of inertia of 22 x 10⁻⁴ kg·m², the motor delivers stable dynamic response during high-precision motion. Weighing 13.0 kg and capable of operating between 0 °C to +45 °C (storage from -20 °C to +80 °C), it adapts to varied installation conditions. The IP65 rating confirms its suitability for wash-down and dusty settings, minimizing maintenance downtime. In industrial applications, this servo motor’s efficiency, feedback accuracy, and rugged design translate into higher throughput, reduced cycle times, and dependable performance in automation systems.
