Product Description:

Bosch Rexroth develops the 3-phase 400 VAC motor MS2N07-B1BNN-ASUG1-NNANN-NN from the MS2N series, with a maximum rotational speed of 6000 rev/minute. It features a 340J of braking system that possess a holding torque of 20.0 Nm and operates on 24 VDC. The brake takes 40 ms of time to engage and 100 ms to disengage.

The MS2N07-B1BNN-ASUG1-NNANN-NN servo motor comes with a low rotational inertia of 22.3 kg·cm² along with a lightweight rotor to tackle rapid speed changes. It operates with a rated speed of 2920 rounds/min and utilizes 2.080 kW of energy along with 4.04 A of current in normal conditions. This motor has rated torque of value 6.80 Nm and it produces 8.2 Nm locked rotor torques at 100 K. Its measured turning effect constant is 1.890 Nm for every 1 A of current utilization at 20°C and its back emf is 115.10 V for every 1000 revolutions. The MS2N07 servo motor possess a winding resistance of 4620 mΩ at 20°C and its thermal characteristics include a 34.90 sec of winding heat dissipation along with 780 sec of overall heat constant to normalize in temperature naturally. Its components possess a leakage capacitance of 0.90 nF and it weighs 11.5 kg with the attached brake. This MS2N07 servo motor is designed with a smooth shaft that is protected with a sealing ring.

The MS2N07-B1BNN-ASUG1-NNANN-NN servo motor uses a single-turn encoder for feedback that functions on DC voltage up to 12 V and provide accurate positioning through its 16-signal cycle. The MS2N07 servo motor uses standard industrial bearings that lasts up to 30000 hours at 60K and it comes with double cable connectors of M23/M17 for electrical connectivity through its rotatable plugs at the terminals.
