Product Description:

The MS2N05-B0BTN-CSHK0-NNNNN-Z1 is a Bosch Rexroth Indramat’s manufactured synchronous servo motor, used in applications where high performance is required. The 20-bit encoder resolution in this servo motor delivers precise feedback to control both the position and speed in a closed-loop system.

At 100 K, the MS2N05-B0BTN-CSHK0-NNNNN-Z1 motor provides a rated speed torque of 2.34 ± 5% Nm to support smooth operation with moderate loads. When greater force is required in applications, this motor can provide the highest torque of 10.6 ± 5% Nm at 100 K while maintaining the same performance. Furthermore, this motor offers 3.75 Nm standstill torque at 60 K, which makes it good at holding loads even when it is not working. Having a keyway with half key balancing, the shaft of this motor provides a reliable and accurate mechanical coupling and torque transfer. A shaft sealing ring is also provided to stop dust or moisture from getting into this motor, thus allowing it to operate longer in tough environments. The MS2N05-B0BTN-CSHK0-NNNNN-Z1 supports safe transport and storage with an allowed ambient temperature range of -25 to +70 °C and a humidity range between 5 and 75%.

The power handling efficiency of this motor is improved by its 5.45 A standstill current to ensure stable current consumption under rated conditions. The 12.7-minute thermal time constant enables this motor to maintain heat accumulation over long durations and minimizes frequent thermal shutdowns. This motor supports installation at up to 1000 meters above sea level, which is viable for operations in a range of industrial conditions without impacting efficiency. This motor’s winding resistance rating of 2.704 Ohms (at 20 °C) aids controlled thermal rise and optimal electrical performance. In this motor, the winding inductivity of 14.09 mH provides effective control over magnetic flux to minimize ripple effects.

Frequently Asked Questions about MS2N05-B0BTN-CSHK0-NNNNN-Z1:

Q: How does the 14.09 mH winding inductivity benefit motor performance?

A: It helps manage current ripple and enhances electromagnetic stability during fast acceleration. This ensures smoother motion control and reduced torque fluctuations.

Q: Why is half key balancing used on the shaft?

A: Half key balancing maintains rotational symmetry and reduces vibration. This is essential for precise and high-speed applications in automation systems.

Q: What role does the shaft sealing ring play in the motor?

A: The shaft sealing ring prevents ingress of contaminants and moisture. It extends motor life in environments exposed to dust or oil.

Q: How does the 12.7-minute thermal time constant affect motor operation?

A: It allows the motor to withstand prolonged thermal loads without quick overheating. This supports continuous operation in high-cycle applications.

Q: Why is a standstill current of 5.45 A important in MS2N05-B0BTN-CSHK0-NNNNN-Z1?

A: It ensures sufficient electromagnetic force to maintain torque without rotor movement. This is vital in holding applications or when position locking is required.
