MAC025C-0-QS-2-E/040-B-1
MAC AC Servo Motors
The Bosch Rexroth Indramat MAC025C-0-QS-2-E/040-B-1 from the MAC AC Servo Motors series operates on 230 V and 50 Hz supplies to deliver a 1.2 kW Power Output at a nominal speed of 3500 min⁻¹. With an Efficiency of 88% and a Current Rating of 5 A, this servo motor balances power delivery and energy economy. Its electromagnetic circuit features a Torque Constant at 20°C of 0.370 Nm/A, a Windings Inductance of 9.1 mH, and a Windings Resistance at 20°C of 9.6 Ohm for predictable, linear control across the operating range. These electrical characteristics ensure smooth torque generation and precise current-to-torque conversion for high-performance motion control applications.
The motor’s mechanical design leverages a Rotor Moment of Inertia of 2.4 × 10⁻⁴ kgm² to enable rapid acceleration and deceleration, meeting the demands of dynamic positioning tasks. It provides a Continuous Torque at Standstill of 0.8 Nm (1.0 Nm with surface cooling) while drawing Continuous Current at Standstill of 2.2 A (2.7 A with surface cooling). For peak demand conditions, the device supports a Maximum Peak of Pulse Current of 12 A, ensuring reliable short-term overload capability. Thermal management is handled by a Thermal Time Constant of 30 min (15 min with surface cooling), maintaining stable winding temperatures under extended duty.
Weighing just 3.2 kg, the MAC025C-0-QS-2-E/040-B-1 offers a compact footprint for integration into tight machine spaces without compromising structural robustness. Its high torque density and optimized thermal characteristics make it ideal for applications requiring frequent start-stop cycles and precise speed regulation. This servo motor delivers dependable, repeatable performance across a wide array of industrial automation tasks.
