MAC025A-0-WS-4-E/040-B-0/WI670LV
MAC AC Servo Motors
The MAC025A-0-WS-4-E/040-B-0/WI670LV, manufactured by Bosch Rexroth Indramat and part of the MAC AC Servo Motors series, is a high-performance industrial servo motor designed for precise automation tasks. This unit delivers a Power Output (P_BM) of 1.2 kW while drawing a Power from the DC Bus (P_DC) of 0.2 kW, ensuring energy-efficient operation. With a Maximum Torque (M_max) of 1.27 Nm and a Short-Term Overload Torque (M_KB) of 0.66 Nm, the motor supports demanding acceleration and deceleration profiles. It operates on a 3-Phase supply at a Frequency of 60 Hz, achieving a Speed at 100% Load (n_100) of 7,220 min⁻¹ and a Speed at 90% Load (n_90) of 5,990 min⁻¹. The integrated Air-Cooled design and a Efficiency of 95% maintain optimal thermal management and reduce downtime.
Performance is enhanced by a robust braking system featuring a Braking Time (t_B) of 24/18 ms, offering rapid deceleration for urgent stop requirements. The motor provides a Holding Torque of 0.27 Nm when stationary and a Detent Torque (M_dN) of 0.33 Nm for secure positioning under load. Its Intermittent Duty Cycle (ED) of 0.25 ensures reliable operation in cyclic applications, while the compact rotor inertia facilitates agile response to control commands. The combination of high output power and controlled torque delivery yields stable operation across the entire speed range. Precision control is further supported by consistent torque output and minimal thermal drift during extended cycles.
Built for seamless integration into industrial automation systems, the MAC025A-0-WS-4-E/040-B-0/WI670LV offers proven reliability in harsh environments. The sturdy construction and high-efficiency cooling mechanism underpin long service intervals and reduced maintenance. Its compatibility with standard servo drives and control platforms ensures straightforward commissioning and scalability. Ideal applications include high-speed pick-and-place machines, indexing tables, and precision assembly equipment. The servo motor’s blend of responsiveness, robustness, and compact form factor makes it a critical component in advanced manufacturing workflows.
