MAC041A-0-FS-4-E/050-A-1/WI668LV
The MAC041A-0-FS-4-E/050-A-1/WI668LV servo motor from Bosch Rexroth Indramat is a high-performance solution within the MAC AC Servo Motors series, designed for demanding industrial automation applications. It delivers a nominal motor speed of 2000 min⁻¹ and a continuous torque at standstill of 9.2 Nm under natural cooling, which increases to 12.0 Nm with surface cooling support. The motor draws a continuous current at standstill of 11 A, rising to 14 A when surface cooling is applied, ensuring optimal thermal management. With a robust mass of 13.0 kg and an IP 65 protection class, this servo motor withstands harsh environments while maintaining precision performance. Its sturdy design and compact footprint make it ideal for integration into complex machinery where space and reliability are critical.
Performance is further enhanced by a maximum peak of pulse current of 54 A, enabling the motor to handle abrupt load changes without compromising control. The rotor moment of inertia of 22 × 10⁻⁴ kg·m² supports stable acceleration and deceleration profiles, minimizing overshoot in dynamic operations. Electrical characteristics include a windings inductance of 16.0 mH and a windings resistance of 1.313 Ω at 20 °C, which together yield smooth current regulation and reduced electromagnetic interference. The torque constant at 20 °C of 0.875 Nm/A and the voltage constant of tachogenerator at 0.0143 Vs/rad (1.5 V/1000 min⁻¹) enable precise closed-loop speed and torque control. Thermal performance is characterized by a thermal time constant of 50 min under natural cooling, reduced to 30 min with surface cooling, ensuring sustained operation under high-duty cycles.
Reliability is assured by the motor’s housing coating of black prime coat (RAL 9005), weather- and acid-resistant, which protects internal components from environmental exposure. An operational permissible ambient temperature range of 0 °C to +45 °C ensures consistent performance across diverse industrial settings. The integrated tachogenerator provides accurate feedback for advanced motion controllers, simplifying integration with existing drive systems and PLC architectures. Rated to IP65, this servo motor resists dust ingress and water jets, making it suitable for food processing, packaging, robotics, and metalworking applications. A one-year warranty further underscores Bosch Rexroth Indramat’s commitment to quality and long-term support.
