Product Description:

The MS2N05-B0BNN-ASDG0-NNANN-NN Servo Motor made by Bosch Rexroth is a precise motion control solution. It comes with features such as phase current and rotational accuracy that are widely used in Industrial robotics, automation and CNC machinery.

The MS2N05-B0BNN-ASDG0-NNANN-NN servo motor has a rated speed of 2850 rpm. It is not equipped with a mechanical brake to hold its position when power is off. Its back electromotive force per unit speed at 20°C is 108.4 volts. During operation it generates a noise level of 75 decibels. The product family of this module is MS2N Synchronous Servo Motors. The mechanical precision of shaft alignment is according to DIN 42955 standards which ensures acceptable limits for runout and alignment. Before thermal or mechanical limits are reached it can produce maximum torque of 11.5 nm. The module cooling mode is IC410 which means it follow self cooling procedure. It has a 4kg of total weight. It has a Hiperface encoder with 128 signal periods per revolution and conforms to Safety Integrity Level 2. The continuous power output of this module at 100K (Kelvin) temperature rise is 1.11 kW. It can provide 3.72 newton meters of torque at a 100K temperature rise above ambient.

The MS2N05-B0BNN-ASDG0-NNANN-NN servo motor shaft is cylindrical without keyway or spline and includes a seal. Its encoder can determine the absolute position of the shaft within one full rotation (0–360°). The module shaft is smooth and sealed for protection. The max speed capability of the motor is 6000 rpm which it can reach safely. Its vibration severity is according to European standard EN 60034-14 and it can work effectively from 0 to 40°C. It uses a dual M17 connector system for power and signal connections.

Frequently Asked Questions about MS2N05-B0BNN-ASDG0-NNANN-NN:

Q: How does the singleturn absolute encoder improve positioning in the MS2N05-B0BNN-ASDG0-NNANN-NN motor?

A: The singleturn encoder provides precise 0–360° absolute position feedback, eliminating the need for homing. This ensures faster start-up and accurate repeatability.

Q: Why is the IC410 self-cooling method beneficial for the MS2N05-B0BNN-ASDG0-NNANN-NN motor?

A: IC410 allows passive heat dissipation without external cooling, reducing system complexity. It’s ideal for compact, enclosed installations with limited airflow.

Q: What advantage does the 128-period Hiperface encoder bring to closed-loop control systems?

A: It enables high-resolution position sensing, ensuring smoother motion and better control accuracy. This enhances responsiveness in dynamic servo applications.

Q: How does the thermal class F rating extend motor lifespan?

A: Class F insulation tolerates higher temperatures, reducing degradation over time. It increases durability under demanding thermal conditions.

Q: What’s the purpose of using a smooth shaft with a shaft seal in this motor?

A: The smooth shaft reduces mechanical wear and simplifies coupling. The shaft seal prevents ingress of dust and fluids, enhancing operational reliability.
