Product Description:
The MS2N07-B1BNN-BMUH1-NNNNN-NN identifies the MS2N Synchronous Servo Motor from Bosch Indramat a trusted manufacturer of automation components. This motor has a standstill current of 4.25 A and a static torque of 7.4 Nm at 60K. At 100K the standstill torque increases to 8.2 Nm with a static current of 4.74 A.
The MS2N07-B1BNN-BMUH1-NNNNN-NN Synchronous Servo Motor supports a maximum torque of 22.8 Nm at 20 °C in cold conditions. It provides a maximum torque of 21.0 Nm at 100K heated conditions. The frame length is defined as B and it includes winding designed for 3000 1/min. The cooling is handled through a self-cooling mechanism which confirms stable operation under continuous load. The holding brake is size 1 and operates electrically. It produces a holding torque of 20.0 Nm and runs at a rated voltage of 24 V. The motor supports a maximum current of 14.8 A and operates up to 6000 rpm mechanically and electrically. The encoder uses Hiperface® technology and is multiturn with 4,096 revolutions. It provides absolute positioning and performs under typical conditions with 128 signal periods. The electrical connections are provided with a double cable interface using M23 and M17 connectors, both rotatable.
The MS2N07-B1BNN-BMUH1-NNNNN-NN Synchronous Servo Motor has a torque constant at 20 °C is rated at 1.89 Nm/A which provides an efficient torque-to-current ratio. To provide stable voltage performance, the voltage constant is 115.1 V/1000 min⁻¹. The winding resistance is measured at 4.62 Ohms and winding inductance is specified as 31.29 mH. The rated speed reaches 2920 rpm at 100K with a rated torque of 6.8 Nm and an operating current of 4.04 A.
