Product Description:
The MS2N05-C0BNN-BSDK0-NNNNN-NN is a high-performance synchronous servo motor with a shaft length of 40 mm. Manufactured by Bosch Rexroth Indramat, this motor features a keyway type shaft with half key balancing and a shaft sealing ring for efficient torque transmission.
The MS2N05-C0BNN-BSDK0-NNNNN-NN motor uses a self-cooling design to maintain internal temperature without the requirement of auxiliary cooling devices. This servo motor is particularly beneficial in space-limited machinery where extra hardware is not feasible. The maximum mechanical speed of this synchronous motor is 6000 revolutions per minute, which allows it to sustain high-speed applications in various automation conditions. This motor has a 10.6-ohm winding resistance at 20 °C to help in stabilizing thermal response under load as well as enhancing the power efficiency of the system. The torque constant of this motor is 1.78 Nm/A at 20 °C for precise torque generation. This motor features a single-turn absolute encoder, which eliminates homing sequences following power loss and gives precise positional information. The voltage constant of this servo motor is 108.4 V/1000 min⁻¹ at 20 °C to support proportional voltage speed output.
This MS2N05-C0BNN-BSDK0-NNNNN-NN servo motor is classified with thermal class 155 (F) according to EN 60034-1 to enable safe and efficient operation under high temperature conditions. An inbuilt thermal warning limit of this motor is defined at 140 °C, which triggers thermal monitoring systems to avoid overheating or system failure. This motor is rated for installation at altitudes between 0 and 1000 meters above sea level without derating. The external coating of this motor is a standard varnish in RAL 9005 black to provide resistance to environmental wear. Designed with five pole pairs, this servo motor provides a well-balanced electromagnetic field for sophisticated torque output and smooth rotational motion.
Frequently Asked Questions about MS2N05-C0BNN-BSDK0-NNNNN-NN:
Q: How does the 140 °C thermal warning protect the motor?
A: It triggers thermal monitoring before damage can occur. This allows connected systems to initiate shutdown or cooling procedures.
Q: What’s the advantage of using five pole pairs in MS2N05-C0BNN-BSDK0-NNNNN-NN?
A: Five pole pairs provide more precise electromagnetic control. It enhances torque stability and smooth motion in demanding servo applications.
Q: How does the encoder’s single-turn absolute feature benefit automation?
A: It retains position data after shutdown without re-homing. This is essential for synchronized multi-axis systems requiring fast recovery.
Q: What’s the significance of 10.6-ohm winding resistance in MS2N05-C0BNN-BSDK0-NNNNN-NN?
A: It limits current draw and manages internal heating. This improves long-term electrical efficiency and motor lifespan.
Q: How does standard varnish coating RAL 9005 support motor durability?
A: It resists environmental factors like humidity and dust. This protects internal components during continuous industrial use.
