Product Description:
Bosch Indramat develops MS2N07-D0BHA-ASVK0-NNNNN-NN as an AC motor with a rated power of 5900 W. It features forced ventilation cooling through a 230 V operating fan, at 50/60 Hz frequency. The motor uses a half-key balance design of shaft with an embedded seal for maximum protection from external pollutants, while the shaft dimensions are 1.26” diameter and 2.28” length.
The MS2N07-D0BHA-ASVK0-NNNNN-NN motor is presented with a flange size of 5.51” and it can be mounted in IM B5 position. It includes a double cable for electrical interface through its rotatable connectors, M40 for power from a 400 VAC source and M17 for encoder signals. This motor delivers a rated speed of 1870 RPM and a rated torque of 30.10 Nm. It provides a maximum torque of 79.7 Nm at 68°F along with 73.20 Nm at 100K. The MS2N motor supports a maximum mechanical speed of 6000 RPM with the equipped typical industrial bearing and it has a low inertia rotor with a moment of inertia equal to 0.00210 kg·m². The unit includes five pole pairs internally and its winding resistance is 1.30 Ohms along with an inductance of 20.20 mH. It produces a measured torque of 2.760 Nm per every 1 A of current and its voltage constant is 167.50 V for every 1000 revolutions.
The MS2N07-D0BHA-ASVK0-NNNNN-NN motor take a time constant of 45.80 seconds for the winding and 10.70 minutes for the body to drop in temperature by half during operations. Its leakage capacitance is rated as 4.1 nF and it favors operations without performance derating up to 1000 m altitude. The MS2N motor comes with HIPERFACE® feedback system that provides outputs of 1Vss analog sin/cos signals and it supply voltage ranges from 7 to 12 VDC, while utilizes 50.0 mA of current.
Frequently Asked Questions about MS2N07-D0BHA-ASVK0-NNNNN-NN:
Q: How does the half-key balance shaft in the MS2N07-D0BHA-ASVK0-NNNNN-NN motor benefit performance?
A: The half-key balance reduces vibration by ensuring smoother rotor dynamics, improving stability at high speeds. It also helps reduce bearing wear and extends operational life.
Q: What advantage does forced ventilation via the 230 V fan provide?
A: The 230 V fan maintains optimal operating temperature even under high load, thus enhancing thermal management. This supports continuous operation without derating.
Q: Why is the HIPERFACE® feedback system used in the MS2N07-D0BHA-ASVK0-NNNNN-NN motor?
A: The HIPERFACE® provides high-resolution analog sin/cos output for precise position feedback, enabling more accurate servo control. It also simplifies wiring by using a compact dual-cable interface.
Q: What is the significance of the low inertia rotor (0.00210 kg·m²) in MS2N07-D0BHA-ASVK0-NNNNN-NN?
A: Its low inertia rotor allows faster acceleration and deceleration, improving dynamic responsiveness. This ensures high-performance control in rapid-motion applications.
Q: How does the leakage capacitance of 4.1 nF affect the motor’s operation?
A: The leakage capacitance indicates the motor’s electrical coupling to ground and helps designers evaluate EMI and insulation performance. It’s crucial for ensuring electromagnetic compatibility in sensitive environments.
