Product Description:

The MS2N05-B0BNN-CMSH1-NNNNN-GE120N2040BN-NN Servo Motor is a product of the Bosch company. Its winding has a quick thermal response time of only 21.2 seconds to reach 63.2% of the final temperature. It is part of the MS2N Synchronous Servo Motors series and it can track the shaft position over 4,096 full turns.

The MS2N05-B0BNN-CMSH1-NNNNN-GE120N2040BN-NN servo motor base or nominal winding configuration speed is 3000 revolutions per minute which helps define its electrical and mechanical performance range. It has the capability of producing 3.72 nm of torque at 2.36 amperes of continuous current. It includes a high resolution encoder with 1,048,576 steps per revolution using ACUROlink communication protocols. 2.29 ampere of current it draws when holding position under rate torque at zero speed. Its nominal operating speed of 2850 rpm is just lower than its base winding speed. It gives fast response to control inputs as it has a 0.00028 kg·m² of moment of inertia. The maximum amount of speed it can safely operate is 6000 RPM for industrial automation applications. The capacitive coupling to ground value is 1.3 nF which influences EMC behavior and filtering needs in high-speed drives.

The MS2N05-B0BNN-CMSH1-NNNNN-GE120N2040BN-NN servo motor has a rotatable M23 single cable connector which makes the installation easier in tight places. The current that builds up in response to voltage changes as represented by winding inductance is 56.4 mH. When it is operating at 20 °C its peak torque availability is 11.5 nm. The whole motor has a thermal time constant of 12.7 min. It is designed for quick accelerations and decelerations as it has a lower rotor inertia. It has a self-cooling capability which means it does not require fans for dissipating heat.

Frequently Asked Questions about MS2N05-B0BNN-CMSH1-NNNNN-GE120N2040BN-NN:

Q: Why does the MS2N05-B0BNN-CMSH1-NNNNN-GE120N2040BN-NN have a multiturn encoder with 4096 revolutions?

A: The multiturn encoder enables absolute position tracking across multiple rotations, which is critical for high-precision positioning. This ensures the motor retains position data even after power loss.

Q: How does the 56.4 mH winding inductance improve motor operation?

A: Higher inductance reduces current ripple, improving smooth torque output and protecting motor electronics. It enhances control stability in precision drive systems.

Q: What is the advantage of a 20-bit encoder in this servo motor?

A: A 20-bit encoder provides over one million discrete positions per revolution, enabling ultra-fine motion control. This results in superior positioning accuracy and feedback resolution.

Q: Why is low rotor inertia important in the MS2N05-B0BNN-CMSH1-NNNNN-GE120N2040BN-NN servo motor?

A: Low rotor inertia allows rapid acceleration and deceleration, essential for dynamic applications. It helps improve response time and reduces overshoot during motion changes.

Q: How does the 1.3 nF leakage capacitance affect EMC performance?

A: Lower leakage capacitance minimizes electromagnetic interference, which helps maintain signal integrity. It also simplifies compliance with EMC standards in complex installations.
