Product Description:

The MS2N07-B1BNN-BMUG1-NNNNN-NN model number is referred to a Servo Motor. Its rated speed is 2920 rpm with 8.2 Nm torque. It offers a reliable and stable operation in demanding applications.

This MS2N07-B1BNN-BMUG1-NNNNN-NN servo motor by Bosch Rexroth supports a standstill current of 4.25 A under 60 K conditions. It is designed to achieve the highest mechanical speed of 6000 rpm. The rotor’s moment of inertia is 0.00223 kg·m² that allows quick acceleration and deceleration. The torque of this MS2N series motor at standstill position is 8.2 Nm at 100 K and 7.4 Nm at 60 K. It features a thermal time constant of 34.9 seconds and 31.29 mH inductance. The design of the motor includes a PT1000 temperature sensor for winding temperature monitoring. The encoder offers 128 signal periods that ensures accurate position feedback. The motor's smooth shaft is fitted with a precision engineered shaft sealing ring that is designed to prevent the ingress of contaminants such as dust, moisture and lubricants. The leakage capacitance of the component is rated at 0.9 nF. At 20 °C of housing temperature, the MS2N07 motor features 22.8 Nm of peak torque.

The MS2N07-B1BNN-BMUG1-NNNNN-NN servo motor is designed with a 24 VDC blocking brake. This brake enables safe position retention during de-energized state. The brake has a maximum connection time of 40 milliseconds. The disconnection time reaches up to 100 milliseconds. This brake supports reliable stopping in emergency or power off conditions. The motor is designed with a standard flange and weighs 11.5 kg that is suitable for medium duty industrial machines. The maximum current supported by the motor is 14.8 A which allows for high dynamic operation when peak torque is needed.
