Product Description:
The MS2N05-C0BTN-CMSL0-NNNNN-NN is a Bosch MS2N synchronous motor built for motion control. It uses a 20-bit resolution encoder ACUROlink that is designed to have 4096 distinct rotations for accurate feedback and has a safety level SIL2/PL d with a ±36 system accuracy. The encoder uses 7-12 V to operate and consume only 60 mA.
The MS2N05-C0BTN-CMSL0-NNNNN-NN motor features a single, rotatable M17 cable connector for power delivery. The motor is designed to produce 3.52 Nm of continuous torque by uses 4.43 A of current. At 100K, its standstill turn effect rating is 7.15 Nm while at 60K the standstill current is 7.1 A. The MS2N05 motor produces 22.6 Nm in cold conditions and possess a torque constant of 0.93 Nm/A at 20°C. Its rotor inertia is measured at 0.00029 kg·m² and it operates at a rated speed of 4090 RPM along with a supported peak mechanical and electrical speed of 6000 RPM. The voltage constant for this motor is 56.3V/1000 RPM speed. At 20°C the winding resistance is 1.26 Ω and possess a minimum inductance of 7.6 mH. The MS2N05 motor’s winding has a thermal value of 36.2 seconds while the thermal time constant for the motor itself is 16 minutes. Th shaft of this motor is balanced and is without a sealing ring while it measures 19mm in diameter and 40mm in length.
The MS2N05-C0BTN-CMSL0-NNNNN-NN motor possess a mounting flange that measures 98 mm and diameter of the centering collar is 50 mm along with 6.6 mm mounting screw holes. The MS2N05 motor uses self-cooling convection method to maintain operation without the need for any external fan. There is no holding brake on board and the brakeless motor weighs about 5.9 kg.
Frequently Asked Questions about MS2N05-C0BTN-CMSL0-NNNNN-NN:
Q: Why does the MS2N05-C0BTN-CMSL0-NNNNN-NN use a 20-bit ACUROlink encoder?
A: The 20-bit encoder offers 4096 revolutions of position feedback, enhancing precision in high-end motion control tasks like robotics or CNC machinery.
Q: How does the torque constant of 0.93 Nm/A benefit applications?
A: It allows for accurate torque output per ampere of current, improving the efficiency and responsiveness in load-sensitive environments.
Q: What does a thermal time constant of 16 minutes indicate for the MS2N05-C0BTN-CMSL0-NNNNN-NN?
A: It shows the motor’s thermal inertia, meaning it resists rapid temperature changes, supporting stability during prolonged or cyclic operation.
Q: How does the ±36 system accuracy affect system performance?
A: This accuracy ensures tight feedback loop control, allowing for minimal deviation in position-critical automation systems.
Q: Why is the shaft built without a sealing ring in the MS2N05 motor?
A: A seal-less shaft reduces mechanical friction and simplifies integration in clean or enclosed systems where contamination is not a concern.
