Product Description:
The model MS2N07-C1BRA-BMVK1-NNNNN-NN is a synchronous servo motor from Bosch Rexroth designed for precision and efficiency. It features five pole pairs that offers smooth torque delivery and optimized power transfer.
The MS2N07-C1BRA-BMVK1-NNNNN-NN servo motor delivers a rated power output of 4.14 kW at a thermal reference of 100 K. Under the same thermal conditions, it provides a continuous rated torque of 9.65 Nm that ensures stable performance and reliable operation in demanding motion control applications. The stator winding resistance of the motor is measured to be 0.895 Ω using a precision digital micro ohmmeter under DC test conditions. This resistance value represents the resistance (line to line) of the copper windings at 20 °C ambient temperature. The maximum torque of the motor at 100 K reaches 42.2 Nm while standstill torque is 18.0 Nm. Its rated current is 8.55 A and the maximum current capacity is 42.7 A. The design of the motor is B5/IM3001 with a PT1000 temperature sensor. A multiturn absolute encoder with 4,096 revolutions ensures accurate positioning. The maximum electrical speed of the motor is 6,000 rpm and flange alignment is standard. Its double cable connections provide convenient wiring options for varied installation layouts.
The Bosch Rexroth MS2N07-C1BRA-BMVK1-NNNNN-NN servo motor incorporates a shaft with half balanced keyways and a shaft sealing ring for durability. The servo motor’s brake provides 20.00 Nm torque with a rated voltage of 24 V and a rated current of 0.78 A. The brake has a maximum connection time of 40 ms and a disconnection time of 100 ms. The holding brake ensures secure load holding when powered off with fast actuation and release times to maintain system responsiveness.
Frequently Asked Questions about MS2N07-C1BRA-BMVK1-NNNNN-NN:
Q: How does the Bosch Rexroth MS2N07-C1BRA-BMVK1-NNNNN-NN maintain positioning accuracy in dynamic industrial operations?
A: The integrated multiturn absolute encoder with 4,096 revolutions delivers precise feedback in complex motion profiles. It ensures stable positioning and synchronization even during rapid acceleration and deceleration phases.
Q: What makes the MS2N07-C1BRA-BMVK1-NNNNN-NN suitable for applications with frequent load changes?
A: Its rotor inertia of 0.00331 kg·m² supports rapid torque response for varying loads. This enables smooth transitions and stable operation under demanding start-stop cycles.
Q: How does the thermal design of the MS2N07-C1BRA-BMVK1-NNNNN-NN affect continuous operation in enclosed systems?
A: A thermal time constant of 9 minutes helps manage heat buildup during extended use. This supports consistent torque delivery without performance degradation in enclosed or high-duty environments.
Q: What benefits does the B5/IM3001 design of the MS2N07-C1BRA-BMVK1-NNNNN-NN bring for system integration?
A: The standardized flange alignment and shaft keyway allow direct compatibility with many mechanical assemblies. This reduces setup time and supports precise coupling with minimal alignment adjustments.
Q: How does the holding brake in the MS2N07-C1BRA-BMVK1-NNNNN-NN enhance operational safety in vertical axis applications?
A: Its 20 Nm brake torque secures the load instantly when power is cut. Fast connection and release times maintain responsiveness while preventing uncontrolled movements.
