Product Description:
The Synchronous Motor MS2N07-D0BNN-AMUG0-NNNNN-NN comes with a torque constant of 2.04 Nm/A at 20 °C for effective torque production. This motor is engineered by Bosch Rexroth Indramat, and it has thermal class 155 (F) as per EN 60034-1 to withstand hotter winding temperatures.
Its winding inductance of 10 mH ensures optimized performance, providing smoother current and lower variations during demanding operating conditions. As far as speed capability is concerned, this motor has a maximum electrical speed of 6000 1/min to handle operations with high dynamic response. The self-cooling mechanism of this servo motor makes it possible to eliminate external cooling devices, and it also eases integration while maintaining operational stability. The MS2N07-D0BNN-AMUG0-NNNNN-NN servo motor features a standard bearing type, which guarantees mechanical reliability, low maintenance requirements, and long lifespan. The encoder system of this motor comprises Hiperface® technology with 16 signal periods, providing accurate positional feedback to improve motion control. The 100K standstill current of this motor is rated at 15 A, which determines solid current load handling even during stationary periods. Furthermore, it includes five pole pairs, which facilitate steady magnetic alignment and increase efficiency throughout the operating range.
This servo motor’s thermal time constant of the winding is 54 seconds, which offers a stable thermal response during continuous operation. This servo motor’s environmental flexibility is provided by an absolute humidity of 1 to 29 g/m³, allowing consistent performance within different climates. This synchronous motor has a leakage capacitance of 4 nF, leading to safe electric properties and consistent insulation. The finish on the exterior of the MS2N07-D0BNN-AMUG0-NNNNN-NN servo motor is done with a standard varnish RAL 9005 black to ensure protection against environmental effects. This motor is in compliance with oscillation level A (EN 60034-14) through the rated speed, ensuring smooth and vibration-constrained operation.
