MAC071B-0-PS-4-C/095-A-0/WA612XX/S001

The MAC071B-0-PS-4-C/095-A-0/WA612XX/S001, Bosch Rexroth Indramat, MAC AC Servo Motors model is a brushless, permanent magnet-excited AC servo motor engineered for precision motion control. It employs electronic commutation to activate windings in sequence, delivering smooth, high-dynamic performance without brushes. Fitted with pre-lubricated bearings for lifetime maintenance-free operation, this motor is optimized for packaging, textile, robotics, and general industrial automation. The design integrates a B-type encoder and tachogenerator feedback for accurate position and speed monitoring.

Detailed specifications emphasize the motor’s robust capabilities: a nominal speed of 4000 min-1 and a torque constant of 0.460 Nm/A ensure rapid response and precise torque delivery. Its rotor inertia of 9.9×10⁻⁴ kgm² combines with a winding inductance of 5.9 mH and winding resistance of 0.72 Ω (at 20 °C) to balance dynamic performance and current control. The unit’s mass of 8.8 kg (including tachogenerator) and compact Motor Length: B and Motor Size: 71 profile simplify integration into space-constrained installations. Cooling is maintained via Cooling Type: Natural Convection, while a Blocking Brake: Not Equipped configuration reduces complexity when brake holding is managed externally. Power is delivered through the standardized Power Connection: Side A interface and the housing conforms to MAC series mechanical dimensions.

Engineers benefit from the MAC071B’s seamless compatibility with standard MAC servo drives and controllers, streamlining commissioning and diagnostics. The lifetime-lubricated bearings and brushless construction impart high reliability and long service intervals in harsh industrial environments. Ideal for synchronized multi-axis systems, robotics, and packaging machinery, this motor maximizes uptime and reduces total cost of ownership.
