MAC041A-0-FS-4-E/050-A-1/WI652LV
MAC AC Servo Motors
The Bosch Rexroth Indramat MAC041A-0-FS-4-E/050-A-1/WI652LV servo motor is a precision-driven actuator in the renowned MAC AC Servo Motors series, engineered to meet the rigorous demands of industrial automation. This high-performance unit delivers a Continuous Torque At Standstill of 9.2 Nm with a Continuous Current At Standstill of 11 A, operating at a Nominal Motor Speed of 3000 min⁻¹ for consistent motion control. Constructed to IP65 standards, the motor housing provides Protection Category IP65 sealing against dust ingress and low-pressure water jets, ensuring durability in harsh environments. With a compact design weighing Mass 13.0 kg and an Insulation Classification F rating, the MAC041A unit offers both mechanical robustness and high thermal endurance. The motor’s Rotor Moment Of Inertia of 22 × 10⁻⁴ kg·m² contributes to agile acceleration and precise braking, while the Thermal Time Constant of 50 min supports sustained operation under continuous load.
Performance characteristics of the MAC041A-0-FS-4-E/050-A-1/WI652LV highlight its finely tuned electrical parameters and dynamic response. The Torque Constant At 20 °C of 0.875 Nm/A demonstrates efficient torque generation per ampere, and the Winding Inductance of 16.0 mH coupled with a Winding Resistance At 20 °C of 1.313 Ω ensures precise current regulation with minimal electrical noise. A Maximum Peak Of Pulse Current of 54 A enables the motor to deliver short bursts of high torque for rapid accelerations. The combination of these characteristics yields smooth motion profiles and high responsiveness for cyclic or positioning tasks. The motor’s thermal management, governed by the 50-minute thermal time constant, maintains stable temperatures during extended operation. Together, these technical features offer a balanced, high-efficiency drive solution capable of meeting stringent cycle time requirements.
Reliability and integration are core strengths of the MAC041A series. Its Protection Category IP65 enclosure and Insulation Classification F ensure long-term performance even under dust exposure and wide temperature ranges from Permissible Ambient Temperature 0 °C to +45 °C to Permissible Storage And Transport Temperature –20 °C to +80 °C. The robust design supports seamless integration into automated production lines, robotics, conveying systems, and packaging machinery. Bosch Rexroth Indramat’s adherence to rigorous quality standards, coupled with a One-year Warranty, provides assurance for continuous uptime and low maintenance requirements. This servo motor is an ideal choice for engineers seeking compact, reliable, and high-precision motion control in demanding industrial applications.
