It offers a maximum connection time of 65 milliseconds and disconnection time of 250 milliseconds. This motor has a mass of 56 kg with the brake and its thermal time of the winding is 97.5 seconds. It possesses a smooth without seal shaft and it operates with the equipped standard bearings.
Frequently Asked Questions about MS2N10-E0BHL-BSBH3-NNNNN-NN:
Q: How does rotor inertia of 0.0141 kg·m² affect motion control?
A: The low inertia allows faster acceleration and more responsive control in dynamic scenarios. It improves precision in positioning and reduces overshoot or lag.
Q: Why is the maximum coolant temperature rise limited to 8 K?
A: Its limiting temperature rise ensures the motor materials and insulation remain within safe thermal limits. It also helps maintain tight dimensional tolerances and magnetic properties under load.
Q: Why is the holding brake voltage 24 VDC in MS2N10-E0BHL-BSBH3-NNNNN-NN?
A: The 24 VDC brake is a common industrial standard that is easily supplied from control systems. It allows fast, safe release under power-up and reliable holding during power loss.
Q: How does the single-turn encoder contribute to safety in MS2N10-E0BHL-BSBH3-NNNNN-NN?
A: The encoder provides precise position feedback necessary for servo control and supports functional safety up to SIL2. It enables monitoring and diagnostics of rotor position without secondary sensors.
Q: Why is the thermal time constant of the winding 97.5 s significant?
A: The time constant indicates how long it takes the winding to heat or cool toward equilibrium. It helps designers size cooling and duty cycles to avoid overheating during frequent load changes.
