Product Description:
The MS2N07-C1BNN-CSSG0-NNNNE-NN from Bosch Rexroth is an AC synchronous motor that features a 140 mm flange diameter and follows B5 mounting orientation. It is equipped with an ACUROlink encoder that ensures high accuracy with 20-bits of resolution and provides category 3 performance level.
The MS2N07-C1BNN-CSSG0-NNNNE-NN motor operates on a 3-phase 400 VAC source and consumes 3.040 kW of rated power along with a normal current of 5.8 A. Its maximum electrical and mechanical rotational speed is specified as 6000 rev/min and it delivers a peak torque of 46 Nm in cold operating conditions. The motor is designed for utilizing natural cooling by dissipating heat through its surface in a specified time of 888 sec as its thermal constant and it comes with an IP65 protection class that makes it dust-tight and water-resistant to suit harsh environmental conditions. It lacks a holding brake in its initial pre-factory design but if the need arises it supports an optional 24V DC holding brake for secure operation. This MS2N motor comes with a PT1000 temperature sensor for effective temperature monitoring and its thermal class allows it to operate under winding temperatures up to 311°F. It has a 15.2 mH winding inductance at 68°F and 1.8 Ohm winding resistance. The motor delivers a 1.88 Nm of constant torque against the usage of every 1 A of current.
The MS2N07-C1BNN-CSSG0-NNNNE-NN motor has a shaft diameter 32 mm and 58 mm length, while it possesses a plain design of shaft with an imposed sealing ring. It has a mass 12 kg and its moment of inertia is specified as 30.5 kg·cm². The unit uses SPEEDCON M23 single power connector for secure connection and it provides an additional grounding terminal for electrical safety.
Frequently Asked Questions about MS2N07-C1BNN-CSSG0-NNNNE-NN:
Q: How does the ACUROlink encoder contribute to positioning accuracy?
A: The ACUROlink encoder ensures up to 20-bit resolution, minimizing positioning error and enhancing control precision in high-speed applications. It enables smooth synchronization with motion controllers by providing reliable feedback.
Q: Why is natural surface cooling (thermal constant) beneficial for this motor?
A: The natural surface cooling eliminates the need for fans or liquid cooling, reducing maintenance and system complexity. With a 14.8-minute thermal constant, it sustains performance under temporary high loads.
Q: How does the PT1000 temperature sensor protect the motor?
A: The PT1000 continuously monitors winding temperature, enabling timely thermal management and shutdown if overheating occurs. This safeguards the winding insulation and maintains long-term reliability.
Q: Why is the torque-to-current ratio important for the MS2N07-C1BNN-CSSG0-NNNNE-NN?
A: A ratio of 1.88 Nm per 1 A indicates efficient conversion of electrical input to mechanical output, supporting responsive control. This high torque-per-amp makes the motor energy efficient under dynamic loads.
Q: How does the 15.2 mH winding inductance influence drive performance?
A: The higher inductance helps filter current ripple, smoothing torque output and reducing acoustic noise. It aids in achieving stable current control during rapid acceleration.
