MAC041A-0-FS-3-E/050-A-1
MAC AC Servo Motors
The MAC041A-0-FS-3-E/050-A-1, Bosch Rexroth Indramat, MAC AC Servo Motors combines high-speed performance with industrial-grade robustness. The motor achieves a nominal speed of 6000 min⁻¹ while delivering a standstill torque of 0.8–2.7 Nm depending on configuration. Its compact black housing (Housing color: Black (RAL 9005)) is protected to IP65 standard, safeguarding internal components from dust and water ingress. Rugged design and precision manufacturing ensure reliable operation in demanding automated systems.
In detailed specifications, the motor supports a standstill current of 3.5–8.4 A and handles peak pulse currents of 19–46 A for rapid torque bursts. The rotor inertia ranges from 2.4×10⁻⁴ to 4.8×10⁻⁴ kg·m², enabling fast acceleration and deceleration with minimal overshoot. Temperature tolerances extend from 0 to +45 °C ambient and –20 to +80 °C storage, while the bearing lifetime exceeds 20 000 h under normal load. Electrical characteristics include a torque constant of 0.23–0.53 Nm/A, winding resistance of 0.7–3.7 Ω, and a tacho-generator constant of 0.0143 Vs/rad to support closed-loop feedback.
Engineers benefit from seamless integration thanks to a smooth shaft with DIN 6885 keyway that mates with standard couplings. Its IP65 protection class and long bearing life ensure dependable uptime in industrial automation, robotics, and packaging lines. The MAC041A-0-FS-3-E/050-A-1’s balanced torque-to-inertia ratio and efficient thermal management translate into precise motion control and reduced maintenance costs.
