MAC041A-0-FS-2-E/050-A-0
MAC AC Servo Motors
The Bosch Rexroth Indramat MAC041A-0-FS-2-E/050-A-0 in the MAC AC Servo Motors series delivers precision motion control with a nominal motor speed of 2000-6000 min⁻¹ and a continuous torque at standstill of 5.0-16.0 Nm. It supports a continuous current at standstill of 11-24.8 A and features a holding brake torque of 6.5 Nm for reliable load holding. Integrated motor feedback ensures smooth rotor position monitoring, while brushless construction minimizes maintenance. Designed for temperatures up to +45 °C and harsh industrial environments, this motor excels in demanding automation tasks.
Mass-optimized and robust, the MAC041A weighs 12.5-23 kg depending on the version and delivers peak performance with a maximum peak of pulse current of 47 A. Its protection category IP65 rating guarantees complete sealing against dust and moisture. The rotor’s moment of inertia ranges from 20 × 10⁻⁴ to 53 × 10⁻⁴ kg·m², balancing dynamic response and load stability. Thermal endurance is evident in a thermal time constant of 100-250 minutes, reducing thermal stress during cyclic operation.
High drive efficiency is supported by a torque constant at 20 °C of 0.31-0.68 Nm/A and a voltage constant of 0.0143-0.0572 Vs/rad, ensuring accurate torque-to-current translation. Winding characteristics include inductance of 0.8-5.1 mH and resistance at 20 °C of 0.12-0.85 Ω, enabling precise current control and minimal overshoot. Sealed bearings with permanent lubrication contribute to extended maintenance intervals and low lifecycle costs, making this servo motor an ideal solution for industrial automation, packaging machines, and robotics where reliability and performance are paramount.
