Product Description:

The MS2N05-B0BNN-CMSL0-NNANN-NN Servo Motor features a keyway shaft with half key balancing, custom flange exactness and advanced 20-bit ACUROlink encoder technology which ensures accurate control and flexibility. It is developed by Bosch Rexroth and it delivers precision and high dynamic performance for industrial automation.

The MS2N05-B0BNN-CMSL0-NNANN-NN servo motor rated speed is 2850 1/min and it is optimized for specific performance or thermal profiles. The module has BN type winding which supports a nominal speed of 3000 RPM and is tuned for balanced performance. It comes with protective black coating (RAL 9005) for corrosion and environmental resistance which is used in standard industrial settings. The module is vital for automation tasks as it can retain its position information even after power loss and is also able to track absolute position over 4096 full revolutions with the help of multiturn encoder. Its product family is MS2N which is known for precision, connectivity and integration with advanced drive systems. This module has a voltage constant of 108.4 V at 20°C which is the back EMF generated per 1000 RPM that helps it size the drive and determine its operational voltage needs. Under peak load or short bursts of torque it can handle electric current up to 8.4 amps without any damage.

The MS2N05-B0BNN-CMSL0-NNANN-NN servo motor can be mounted only via a flange. To protect it from heat it includes a precision temperature sensor (PT1000). It can be installed simply as it comes with no fan and cools itself through natural convection. It cannot hold position passively in power-off conditions because it has no internal brake mechanism. It comes with a medium-length frame which affects torque and physical dimensions.

Frequently Asked Questions about MS2N05-B0BNN-CMSL0-NNANN-NN:

Q: How does the low rotor inertia benefit the MS2N05-B0BNN-CMSL0-NNANN-NN servo motor?

A: Low rotor inertia allows faster acceleration and deceleration. This makes the motor highly responsive in dynamic industrial motion control tasks.

Q: Why is a single cable connection used in the MS2N05-B0BNN-CMSL0-NNANN-NN motor?

A: The single M23 cable simplifies wiring and reduces space. It integrates power and signal transmission for efficient installation.

Q: What is the significance of the multiturn encoder in positioning applications?

A: The multiturn encoder retains position over 4096 revolutions. This ensures absolute tracking even after power loss or system resets.

Q: How does the self-cooling design affect motor operation?

A: Self-cooling allows the motor to operate without external fans. This simplifies design and reduces maintenance in enclosed environments.

Q: Why does the MS2N05-B0BNN-CMSL0-NNANN-NN use a PT1000 sensor?

A: The PT1000 sensor provides accurate thermal monitoring. This protects the motor from overheating and improves long-term reliability.
