Product Description:

The MS2N07-B1BNN-BMUL0-NNNNN-NN Synchronous Motor produces a nominal mechanical power output of 2.08 kW at 100K, with the ability to sustain consistent operation in harsh industrial applications. This motor is Bosch Rexroth Indramat's product, and it consumes a maximum of 14.8 A of current to provide strong bursts of torque when required.

The speed rating under 100K of this servo motor is 2920 RPM, which means high-speed motion can be achieved with stable acceleration and deceleration capabilities. This MS2N07-B1BNN-BMUL0-NNNNN-NN Synchronous Motor includes a ratio of torque-to-current of 1.89 Nm/A at 20 °C for effective transformation of electrical input into mechanical torque. For orderly thermal operation, this motor has a thermal time delay of 13 minutes to provide protection against overheating during peak usage hours. The locked-rotor torque of this servo motor is rated at 7.4 Nm at 60K, ideal for applications that need high holding torque in stationary positions. The coil inductance of 31.29 mH of this motor supports smoother torque characteristics and less current ripple to enhance control stability under different load conditions. This servo motor is designed with a standard-grade feedback system with 128 increments, built on Hiperface protocol, and is compatible with both SIL2 and PLd safety levels.

The rotor of this motor is classified as moderate inertia and provides a fair compromise between responsiveness and torque output, well suited for mid-load applications. The shaft end of the MS2N07-B1BNN-BMUL0-NNNNN-NN motor has a key slot with half-key balancing to accommodate safe and aligned mechanical coupling. The connector system of this synchronous motor contains swivel-mounted twin-cable M23/M17 connectors with flexible installation and optimized cable routing in cramped enclosures. The surface of this synchronous motor is coated with standard varnish in RAL 9005 black, which allows basic protection against wear and dust while maintaining industrial appearance standards. Built to function within ambient temperatures of 0 to 40 °C, the MS2N07-B1BNN-BMUL0-NNNNN-NN performs consistently under normal factory conditions.

Frequently Asked Questions about MS2N07-B1BNN-BMUL0-NNNNN-NN:

Q: Why is a torque-to-current ratio of 1.89 Nm/A important?

A: It ensures efficient torque generation from electrical input, enhancing motor control precision. This is especially useful for applications with variable loads.

Q: How does the 13-minute thermal time delay impact reliability?

A: It allows the motor to dissipate heat before reaching thermal limits. This increases motor lifespan during cyclic operations.

Q: What role does the key slot with half-key balancing serve?

A: It helps prevent shaft imbalance during rotation. This improves mechanical stability in high-speed applications.

Q: Why is moderate rotor inertia beneficial in MS2N07-B1BNN-BMUL0-NNNNN-NN?

A: Moderate inertia balances responsiveness and stability. It is ideal for systems requiring controlled motion without overshoot.

Q: How does 31.29 mH inductance affect motor performance?

A: Higher inductance smooths current flow and reduces torque ripple. It improves motion accuracy in sensitive automation systems.
