Product description

With IP65 protection and natural-convection cooling, the Bosch Rexroth MAC071C-0-NS-4-C/095-A-1/WI520LX is clearly positioned within the Indramat MAC series. This permanent-magnet AC servo motor in size 071C has an NS winding rated for 3,000 min⁻¹. At standstill, the motor design provides 6.6 Nm continuous torque at 11.0 A continuous current. Its data include a torque constant of 0.600 Nm/A, winding resistance of 0.69 Ω, and winding inductance of 7 mH. The peak pulse current is 55 A. Type-code position 4 denotes tacho feedback with a mounted incremental or absolute encoder; the encoder code on this motor is WI520LX. The centering diameter is 95 mm, while the power connection is located on side A of the housing. Type-code position 1 identifies the electrically released standard holding brake. It operates at 24 V DC and 0.6 A and provides 3 Nm holding torque. The brake releases within 30 ms and clamps within 15 ms. The naturally cooled motor has a thermal time constant of 45 minutes. Its insulation class is F, and the permitted ambient temperature range is 0 to +45 °C. Storage and transport are specified between -20 and +80 °C, with a maximum installation elevation of 1,000 m. Motor dimension A remains 292 mm with the standard holding brake. Size 071C, 95-mm centering, and connection side A further identify the mechanical version. Total weight from the 11-kg base motor, brake, and mounted encoder is conservatively estimated at approx. 12 kg.
