Product Description:

The MS2N07-D0BHL-BMVG2-NNNNN-NN is a synchronous servo motor from Bosch Rexroth Indramat that comes equipped with a water-cooling type. This cooling method provides uniform heat dissipation under heavy-duty cycles and ensures good performance over a long duration of use.

This motor has a maximum current rating of 36.4 A, which allows for temporary overloads without loss of efficiency. Its environmental resilience is supported through the relative humidity tolerance of 5% to 95%, and it is suited for diverse installation environments. It features a standard encoder with 128 signal periods Hiperface, which provides accurate position and speed feedback for motion systems. The rotor's moment of inertia of the MS2N07-D0BHL-BMVG2-NNNNN-NN motor is 0.0021 kgm², offering a balance between stability and responsiveness in operation. Its noise emissions are regulated with a sound pressure level of 75 dB(A) ±3 dB(A) to be in compliance with industrial noise standards. Its component features a leakage capacitance value of 4.1 nF, representing electrical properties during system integration. For safe holding functions, this servo motor incorporates an electrically released brake with a torque capacity of 36 Nm. This brake is equipped with a maximum connection time of 60 ms, providing quick actuation for safety purposes.

This servo motor’s design is based on B5 / IM3001 mounting with an onboard PT1000 sensor. The torque transmission by this synchronous motor is effective with a torque constant of 2.76 Nm/A at 20 °C. At higher temperatures, the MS2N07-D0BHL-BMVG2-NNNNN-NN motor delivers a standstill torque of 22 Nm at 60K temperature rise to maintain stable performance under load. This motor’s 20.2 mH winding inductance aids stable current control and uniform torque development within the operating range. The thermal endurance of this motor is specified in terms of insulation class 155 (F) according to EN 60034-1 for long life under temperature exposure.
