Product Description:
The Bosch Rexroth Indramat’s manufactured MS2N05-C0BNN-BMDG1-NNNNN-NN is a Synchronous Servo Motor that is made for high-precision industrial use where efficiency and reliability are of paramount importance. With a standard encoder featuring 128 signal periods, this synchronous motor provides precise position sensing.
This motor’s encoder supports the Hiperface® interface, which supports SIL2 (Safety Integrity Level 2) and PL d (Performance Level d) conformities to fulfill safety and control requirements in automated environments. The multiturn design of this encoder provides 4,096 revolutions absolute so that the system can monitor precise shaft position over numerous full turns. The cooling mechanism of the MS2N05-C0BNN-BMDG1-NNNNN-NN synchronous motor is based on self-cooling, and it does not require any external cooling devices, thus reducing the complexity of the entire system design. The electrical connection of this motor consists of a double cable connection with 2x M17 rotatable connectors to facilitate higher installation flexibility. This synchronous motor has a thermal class 155 (F) according to EN 60034-1 to allow sustained operation under extended load conditions without any heat build-up.
This servo motor provides a voltage constant of 112.7 V/1000 min⁻¹ at 20 °C to define the back EMF generated per speed unit. The integrated electrically released holding brake provides secure positioning when this motor is at rest. The brake offers a 10 Nm holding torque, which is enough to hold this motor’s shaft under load. The rated current for the holding brake is 0.73 A to provide controlled actuation with reduced power consumption. The MS2N05-C0BNN-BMDG1-NNNNN-NN motor weighs a total of 7 kg with the holding brake, and it has 5 pole pairs for smooth running at mixed speeds. In this synchronous motor, the winding inductance of 30.3 mH contributes to improving current control by reducing harmonic distortion.
Frequently Asked Questions about MS2N05-C0BNN-BMDG1-NNNNN-NN:
Q: How does the 30.3 mH winding inductance affect motor performance?
A: It improves current regulation and reduces torque ripple. This enhances motor smoothness during low-speed or precision operations.
Q: Why are rotatable M17 connectors used in the MS2N05-C0BNN-BMDG1-NNNNN-NN?
A: Rotatable connectors provide flexible cable alignment in tight spaces. This minimizes strain on connections and simplifies maintenance.
Q: What role does the 16-minute thermal time constant play in motor use?
A: It determines how quickly the motor reaches thermal stability. This helps in planning duty cycles without risking overheating.
Q: How does the Hiperface® protocol improve system integration?
A: It allows both encoder data and parameter storage over one connection. This supports plug-and-play setup and diagnostics.
Q: Why is the encoder rated for SIL2 and PL d important?
A: It ensures compliance with safety standards in automated environments. This enhances reliability in critical motion control systems.
