Product Description:
The MS2N07-D0BHN-DMSH2-NNNNN-NN is an AC servo motor that is produced by Bosch with an optical advanced 24-Bits ACUROlink encoder. Its encoder is designed with a multiturn design that provides 4096 revolution periods and 20” of system accuracy for precise positioning. This motor is rated for 4600 W of nominal power and it provides a maximum shaft speed of up to 6000 rev/min.
The MS2N07-D0BHN-DMSH2-NNNNN-NN motor generates a rated standstill torque of 28.2 Nm at 100K and utilizes 11.1 A of current. It uses permanent magnet synchronous technology with 5 poles pairs that contributes in its efficient torque generation and it operates at a normal speed of 2000 rev/min. The motor gets self-cooled naturally for efficient operations and possess 0.312 h of heat dissipation value. It is designed with a smooth shaft, without a sealing ring and it measures 58 mm in length. The MS2N07 motor features a holding brake of size 2 that offers a 36 Nm of torque and an electrically released design for quick operation. The brake possess 850 J of energy and it takes 60 ms to connect as well as 200 ms to disconnect. The unit offers a maximum torque of 73.2 Nm at rated conditions of 100K and at the same temperature it uses 8.85 A of current. It possesses a 1.30 Ohms of winding impedance and its torque constant is measured as 2.76 Nm/A.
The MS2N07-D0BHN-DMSH2-NNNNN-NN motor is provided with M23 connector for electrical connectivity from a 400 VAC supply source and as a B5 unit it allows only flange mounting. It has a rotor inertia of 0.00251 kg·m² and offers low vibrations due to its classification of level A resonance. The motor comes with fitted thermistor in the winding for overheating protection and it is coated from outside for weather proofing.
