Product Description:
The MS2N05-C0BTN-ASDG0-NNANN-NN is a high-performance synchronous servo motor designed with high precision for automation systems that need controlled motion, high speeds, and regulated thermal management. This motor is manufactured by Bosch Rexroth Indramat, and it has a maximum turning speed of 6000 min⁻¹, which is appropriate for fast acceleration in dynamic applications.
This servo motor has a rated speed of 4090 1/min at 100K to provide stable rotational performance under thermal load during continuous operation. The MS2N05-C0BTN-ASDG0-NNANN-NN motor has 5 pole pairs, which contributes to smoother torque output and higher resolution. The standstill torque of this motor is rated at 6.10 Nm at 60K to provide high holding torque under static load. The electrical properties of this motor include a winding resistance of 1.26 Ohms at 20 °C to define current consumption and heat production when operating nominally. The winding inductance of this synchronous motor has a value of 7.6 mH to ensure effective ripple current suppression. The voltage constant of this motor is 56.3 V/1000 min⁻¹ at 20 °C to characterize the back EMF and is important for adjusting drive electronics and optimizing system response. The winding's thermal time constant of this servo motor is 36.2 seconds to regulate heat buildup during load transitions.
The MS2N05-C0BTN-ASDG0-NNANN-NN synchronous motor is built with the thermal class 155 (F) as per EN 60034-1 to tolerate higher winding temperatures without insulation breakdown. The encoder type of this motor is basic and has 16 signal periods, and supports position detection through the Hiperface interface, which enables high-speed synchronized communication with servo controllers. This motor is designed to operate in the ambient temperature range of 0 to 40 °C, and its shaft has 40 mm to allow for compatibility with standard mechanical interfaces.
Frequently Asked Questions about MS2N05-C0BTN-ASDG0-NNANN-NN:
Q: How does the 7.6 mH winding inductance improve motor operation?
A: It reduces current ripple during fast switching operations, helping maintain smoother torque delivery. This also enhances control stability during dynamic load changes.
Q: Why is a thermal class 155 (F) significant in the MS2N05-C0BTN-ASDG0-NNANN-NN?
A: It allows the motor to handle higher winding temperatures without insulation damage. This extends service life during long-duty cycles.
Q: How does the Hiperface encoder improve motion control accuracy?
A: Hiperface provides high-resolution feedback for real-time motor position correction. This ensures smoother synchronization in closed-loop systems.
Q: What role does the 36.2-second thermal time constant play in performance?
A: It delays heat saturation in windings, allowing time for cooling between load peaks. This protects internal components during sudden load changes.
Q: How does the rated speed of 4090 1/min at 100K benefit motor efficiency?
A: It supports high rotational output while maintaining safe operating temperatures. This enhances consistent productivity in thermal-sensitive environments.
