Product Description:

The MAC025C-0-QS-2-E/040-B-1 servo motor is manufactured by Bosch Rexroth Indramat. It’s all about precision control. This comes from balancing electrical and mechanical factors. Each one is optimized for performance and reliability. The motor has a permanent magnet-excited rotor that produces the torque for a wide range of industrial applications. The rotor has low inertia because of the chosen permanent magnets. This feature enables quick acceleration and deceleration. So, the motor is great for tasks needing dynamic motion control. The electrical specs are impressive, too. 230V and 50Hz, 1.2kW and 88% efficient performance and energy efficiency.

The torque constant of 0.370 Nm/A at 20°C means the motor can convert electrical current into mechanical torque efficiently. This linearity makes the control algorithms simpler and the motor behavior more predictable. The mechanical design of the MAC025C-0-QS-2-E/040-B-1 motor matches its electrical capabilities. The rotor’s moment of inertia is 2.4 × 10⁻⁴ kgm², so it can change speed quickly, essential for applications that require fast and precise movements. The motor can deliver continuous torque of 0.8 Nm at a standstill and 1.0 Nm with surface cooling, it’s versatile and can handle demanding scenarios. The thermal management system has a time constant of 30 minutes. With surface cooling, this drops to 15 minutes. This setup helps maintain stable operation under continuous load.

To top it all, there are thermo switches in the windings and stator housing to protect the motor from thermal overload. The MAC025C-0-QS-2-E/040-B-1 servo motor’s performance goes beyond its electrical and mechanical specs. It can handle a maximum peak pulse current of 12A, so it can handle high-demand applications. The compact design (3.2kg) allows it to be integrated into many industrial environments. The holding brake (optional) ensures secure positioning when the motor is not powered when load stability is critical. The MAC025C-0-QS-2-E/040-B-1 servo motor shows how well integrated electromechanical design works. It’s a great solution for industrial automation challenges.
