Product Description:
The MS2N07-B1BNN-BSUG0-NNNNN-NN is a synchronous motor that has a 21 Nm peak torque with a 100K operating temperature and can be used in high-demand dynamic load applications. This motor runs using a rated electrical current of 4.04 A at 100K to enable controlled and consistent performance for rated thermal conditions.
The rotor's inertia of rotation of this MS2N07-B1BNN-BSUG0-NNNNN-NN motor is 0.00197 kg·m², which aids smooth transition during motion, enhances responsiveness, and allows for fast adjustment to changes in speed. This motor’s resistance in winding is 4.62 Ohms at 20°C to make energy consumption efficient and thermal responses predictable. The stator winding's thermal response time is 34.9 seconds for stable heat dissipation and enabling this motor to cope with thermal loads during prolonged running. For position and feedback control, this motor features an absolute encoder single-turn type for accurate positioning across one full revolution. The number of pole pairs in this motor is 5, which is an added factor towards increased commutation resolution and torque ripple smoothness. This servo motor’s shaft design is plain cylindrical, which provides compatibility with the majority of coupling possibilities in mechanical assemblies.
The MS2N07-B1BNN-BSUG0-NNNNN-NN motor incorporates a standard bearing type for mounting, which is capable of providing repetitive rotational accuracy and reducing vibration when under load. The mounting face tolerance of this motor is within the normal precision class, to facilitate a dependable mechanical fit during fitting. The connection system for this synchronous motor comprises a rotatable connector dual-cable interface (M23/M17) for easy electrical integration and cable routing through tight spaces. This motor’s vibration severity class rating is Class A, as per EN 60034-14, to support its usage in environments where low vibration is essential. It also has a noise emission rating of 75 dB(A) ±3 dB(A), which makes it suitable for applications with a need for low acoustic disturbance.
Frequently Asked Questions about MS2N07-B1BNN-BSUG0-NNNNN-NN:
Q: How does the absolute single-turn encoder in this motor benefit motion control?
A: The single-turn encoder ensures precise positioning within one shaft rotation, enhancing accuracy. This is crucial for applications that require exact angular measurements and repeatable movement.
Q: Why is a 5 pole pair design used in the MS2N07-B1BNN-BSUG0-NNNNN-NN?
A: More pole pairs improve torque smoothness and allow finer control at lower speeds. This enhances synchronization in servo systems under varying load conditions.
Q: How does the dual-cable M23/M17 setup support flexible installation?
A: It separates power and signal lines, reducing interference and simplifying cable routing. The rotatable connectors make it easier to manage in space-limited cabinets.
Q: What is the significance of Class A vibration rating in this servo motor?
A: Class A vibration limits reduce mechanical stress and extend bearing life. It ensures consistent operation in sensitive mechanical assemblies.
Q: Why is the rotor inertia value of 0.00197 kg·m² important?
A: This low inertia supports rapid acceleration and deceleration cycles. It improves responsiveness in fast-moving automation sequences.
