Product Description:
The MS2N07-D0BNN-ASUH2-NNNNN-NN is developed by Rexroth as an AC synchronous motor from the MS2N series that operates on 400 VAC and utilizes 5.2 kW of nominal power. It has a rated speed of 2940 r/min and at standstill it produces a torque of value 22 Nm, while its maximum supported torque at 20°C is 79.7 Nm.
The MS2N07-D0BNN-ASUH2-NNNNN-NN motor uses self-cooling through natural radiation/convection and it operates effectively between 0°C and 40°C, with derating options up to 60°C. It features an encoder feedback system that provides 16-signal periods and allows precise speed and position control up to 520”. The unit also includes a PT-1000 temperature sensor for thermal protection, with warning and disconnection thresholds set at 140°C and 145°C, respectively. It is designed with a seal less smooth shaft and its protection class is IP64. This MS2N07 motor is equipped with a holding brake option that is electrically released at 24V DC ±10% to ensure the motor stays in position when not in operation. Its brake possesses 16.5 Nm of dynamic torque and kg·m² of inertia, along with 850 J of peak braking energy. The unit is provided with M23 and M17 rotatable connector for separate power and feedback connections.
The MS2N07-D0BNN-ASUH2-NNNNN-NN motor complies with the EMC directive 2014/30/EU to ensure safety and compatibility with other equipment. It uses standard greased bearings that lasts up to 30000 h at 60K and they provide a peak mechanical speed of 6000 r/min. The motor has a back emf value of 124.1 V/1000 rotations and its winding has an inductive value of 10 mH. Its peak overload current is measured as 49.5 A, while in normal conditions of 100K it uses a continuous current of 9.35 A.
Frequently Asked Questions about MS2N07-D0BNN-ASUH2-NNNNN-NN:
Q: What benefit does the encoder feedback provide in the MS2N07-D0BNN-ASUH2-NNNNN-NN?
A: The encoder feedback enhances positioning accuracy by providing high-resolution speed and position data. This enables smoother control and tighter loop tuning during dynamic operations.
Q: Why is self-cooling via natural radiation/convection used rather than forced cooling?
A: Its self-cooling simplifies design by eliminating external fans, reducing maintenance and noise. It’s ideal for environments where airflow may be limited or dust accumulation is a concern.
Q: How does the PT1000 temperature sensor improve the MS2N07-D0BNN-ASUH2-NNNNN-NN’s longevity?
A: The PT1000 monitors internal temperatures and triggers warnings or shutdowns at defined thresholds. This protects winding insulation and bearings from thermal damage.
Q: Why is a holding brake option valuable on the MS2N07-D0BNN-ASUH2-NNNNN-NN?
A: The holding brake ensures the motor remains stationary when powered off, critical in vertical or safety-sensitive applications. It provides immediate torque retention during shutdown.
Q: How does the M23 and M17 rotatable connector design benefit maintenance?
A: The rotatable connectors simplify cable routing and orientation flexibility during installation. This reduces strain on cables and speeds up service procedures.
