Product Description:
The MS2N07-D0BNN-CMSK0-NNANN-NN is a synchronous motor, which has a top mechanical speed of 6000 1/min to sustain required motion profiles. It is made by Bosch Rexroth Indramat, and it has a winding inductance of 10 mH for controlled current flow and stable electromagnetic performance.
The MS2N07-D0BNN-CMSK0-NNANN-NN servo motor is designed to operate efficiently in a relative humidity level from 5% to 95% without degrading its performance. Under the rated current of 9.35 A at 100K, this motor is efficient in energy conversion while remaining thermally stable. Under standstill conditions, this motor supports a current of 11.55 A at 60K, which is helpful in providing high torque at low speeds. The voltage constant of 124.1 V/1000 min⁻¹ at 20 °C defines this motor’s strong electrical-to-mechanical conversion capability, allowing precise speed regulation under varying loads. For position feedback, this servo motor features a multi-turn 4096-revolution absolute encoder to provide precise motion control and repeatable positioning. This motor’s shaft features a keyway and half-key balancing, supported by a shaft sealing ring to provide protection from contamination and assure long-term operation. The outside surface of this motor is coated with a standard varnish, RAL 9005 black, that provides strength and resistance to outside wear conditions.
The MS2N07-D0BNN-CMSK0-NNANN-NN motor provides a maximum torque of 79.7 Nm at 20 °C (cold), allowing it to support heavy loads in automation systems. It utilizes a self-cooling design, avoiding the use of external cooling devices and making it easy to integrate with various machine configurations. This servo motor’s 75 dB(A) +3 dB(A) sound pressure level meets industrial noise regulations while providing operator comfort. The winding's thermal time constant of 54 seconds emphasizes efficient heat dissipation by this motor. This motor also incorporates a leakage capacitance of 4 nF, ensuring minimum electrical interference and stable system integration.
Frequently Asked Questions about MS2N07-D0BNN-CMSK0-NNANN-NN:
