Product Description:

Bosch produces the servo motor MS2N10-E0BHL-BSBK3-NNNNN-NN with a rated current of 55.20 A at 100K and its nominal torque at the same temperature is specified as 137 Nm. It comes with an integrated size 3 holding brake that supplies 90 Nm torque and possess 0.0027 kg·m² of inertia. This motor is provided with M58 and M17 connectors for power and feedback connectivity.

The MS2N10-E0BHL-BSBK3-NNNNN-NN motor features a rotor inertia of 0.01410 kg·m² for dynamic responsiveness at high speeds and its torque constant at 68 °F is 2.9 Nm/A. It relies on liquid cooling for maintaining ambient thermal range and its coolant duct is manufactured from stainless steel. The duct compensates a recommended volume of 0.35 liters and its pressure drop at minimum flow is recorded as 0.36 bar, while its maximum inlet pressure of coolant is 6 bar. This motor delivers 234.0 Nm of cold maximum torque at 68 °F and its maximum mechanical speed supported is 6000 rev/minute. Its rated rotational speed at 100K is 1540 rev/minute and it consumes a rated power of 2210 W. The MS2N10 motor is rated for a stationary current of 65.40 A at 100K conditions and its peak current utilization can go up to a value of 102.5 A under full load. Its winding resistance at 68 °F is 0.2440 Ohms and its inductance is 7.430 mH.

The MS2N10-E0BHL-BSBK3-NNNNN-NN motor is constructed with 5 pole pairs and it has a keyway shaft orientation. The unit possess 5.20 minutes of thermal time constant and it is equipped with an HIPERFACE technology encoder for feedback that possess single revolution design. Its encoder provides 1 VSS of sinusoidal signals as output and offers 120” of accuracy for positioning through its 128-signal period design.

Frequently Asked Questions about MS2N10-E0BHL-BSBK3-NNNNN-NN:

Q: How does the 90 Nm brake in MS2N10-E0BHL-BSBK3-NNNNN-NN help in safety or holding loads?

A: The integrated holding brake prevents motion when power is lost, securing the axis under load. It ensures the motor holds position without external mechanical locks.

Q: Why choose HIPERFACE encoder technology in MS2N10-E0BHL-BSBK3-NNNNN-NN?

A: HIPERFACE provides high-resolution, one-cable digital feedback, reducing wiring complexity. It enhances synchronization and minimizes electromagnetic interference.

Q: What is the benefit of a liquid cooling duct in MS2N10-E0BHL-BSBK3-NNNNN-NN?

A: Liquid cooling allows the motor to run at higher continuous currents without overheating. It yields more stable performance, especially in compact, high-power installations.

Q: Why is the rotor inertia (0.0141 kg·m²) significant in MS2N10-E0BHL-BSBK3-NNNNN-NN?

A: Lower rotor inertia enables faster acceleration and deceleration, improving dynamics. It helps the motor respond quickly under varying loads.

Q: How does the 5.2 min thermal time constant affect operation of MS2N10-E0BHL-BSBK3-NNNNN-NN?

A: The time constant gives an estimate of how fast the motor heats or cools under load changes. It helps in designing duty cycles and managing temperature control strategies.
