Product Description:
The MS2N06-D0BNN-BSUL2-NNNNN-NN is a high-speed Synchronous Servo Motor manufactured by Bosch Rexroth Indramat for applications with repetitive torque and precise feedback requirements. This motor’s mass is 10.5 kg, which allows it to be compact yet powerful enough for space-limited installations.
The MS2N06-D0BNN-BSUL2-NNNNN-NN servo motor uses a self-cooling system to eliminate the necessity for external cooling devices. The winding's thermal time constant of this servo motor is 38.6 seconds to sustain long-run operational loads without thermal buildup becoming a critical issue. Integrated with a standard Hiperface encoder with 128 signal periods, this synchronous motor provides high-resolution feedback. This encoder is of single-turn, 1 revolution absolute type and provides consistent position information within one revolution cycle. The 18 millihenries (mH) rated winding inductance of this motor enables stable current flow and electromagnetic response under dynamic conditions. The voltage constant value at 20 °C is 103.5 V/1000 min⁻¹, which aids in consistent operation by this motor and torque-to-speed conversion efficiency. In terms of braking operation, this synchronous servo motor comes with a holding brake rated at 0.75 A, which engages reliably when the power is cut off. This also provides stability during load holding and improved machine accuracy.
This servo motor’s holding torque is 15 Nm, ideal for applications needing heavy static force during standstill operations. This servo motor also provides protection with an IP64 rating, which protects the internal parts against dust and water spray. The MS2N06-D0BNN-BSUL2-NNNNN-NN synchronous servo motor uses a shaft type with keyway and half-key balancing to maximize torque transfer without a shaft sealing ring. This design also reduces maintenance and enhances mechanical alignment. Mechanically, this servo motor conforms to the B5 / IM3001 mounting design and is equipped with two PT1000 sensors for accurate thermal monitoring.
Frequently Asked Questions about MS2N06-D0BNN-BSUL2-NNNNN-NN:
Q: Why is a Hiperface encoder with 128 signal periods used?
A: It allows high-resolution feedback for closed-loop systems, ensuring fine position accuracy. This is essential for precision automation tasks.
Q: What advantage does the keyway with half-key balancing offer?
A: It reduces vibration and improves torque transmission efficiency. This contributes to smoother mechanical operation during rotation.
Q: How does the absence of a shaft sealing ring affect performance?
A: It reduces friction on the shaft, enhancing efficiency and mechanical lifespan. It's beneficial where sealing is not a primary concern.
Q: Why is the PT1000 sensor included in the MS2N06-D0BNN-BSUL2-NNNNN-NN?
A: The PT1000 sensor provides accurate winding temperature monitoring. This supports thermal protection and improves operational safety.
Q: What does the thermal time constant of 38.6 seconds indicate?
A: It defines the motor’s thermal inertia during heating. A higher constant means slower temperature rise, useful in dynamic duty cycles.
