MAC071C-0-NS-4-C/095-A-0/WA612XX/S001

The MAC071C-0-NS-4-C/095-A-0/WA612XX/S001 is a high-performance AC servo motor from Bosch Rexroth Indramat in the MAC AC Servo Motors series. With a continuous torque at standstill of 6.6 Nm and a nominal motor speed of 3000 RPM, it delivers precise motion control in applications requiring rapid response. This motor features a side-A power connector and an integrated C encoder, making it ideal for drive systems that demand accurate feedback and agile starts. Its primary function is to provide reliable torque and speed control in sectors such as robotics, packaging, and machine tooling.

This motor sustains a continuous current at standstill of 11.0 A and can handle a maximum peak of pulse current of 55 A, ensuring short bursts of high torque when needed. The torque constant at 20 °C is 0.6 Nm/A, enabling efficient conversion of electrical input into mechanical output. Electrical characteristics include a windings inductance of 7 mH and windings resistance at 20 °C of 0.69 Ω, which contribute to stable current flow and precise torque generation. The rotor’s moment of inertia of 12.9 × 10^-4 kg·m² and a thermal time constant of 45 min ensure consistent performance under varying load cycles.

Constructed to DIN 40 050 standards, the motor housing and covers offer robust protection against external objects and moisture. Key components, including the output shaft and power supply terminals, carry an IP 65 rating, while the cooling section is rated IP 24 and the blower motor IP 44. The motor’s size 71 frame and length C configuration, combined with natural convection cooling, deliver durability and maintenance-free operation. Weighing 11 kg, this compact unit integrates seamlessly into systems at elevations up to 1000 m and ambient temperatures from 0 °C to 45 °C. Its adherence to international protection standards and efficient thermal management ensures reliable performance and longevity in industrial environments.
