I think the the pump curve is not attached properly. I have attached it again. http://files.engineering.com/getfile.aspx?folder=d844c3a8-d092-4c22-8a1f-9f1b5be0231e&file=Pump_-_Speed_Torque_Curve.pdf
Thanks ScottyUK and Skogsgurra.
I forgot to mention the motor rating. It is 0.55 kW, 1400 rpm, 24 V DC rated, suitable for Zone 2 area.
Since the pump starting torque is high, the motor vendor has recommended the starting current as 5 times FLC. The required pump torque is 20Nm. Please refer...
I beleive the speed torque curve of a DC motor is different from a AC motor. Why is this so?
Do any one have typical Speed torque curve of both DC motor and pump?
Please let me know what is the starting current (in terms FLC) normally recommended for DC motors.
How to decide series resistance value in case of DC compound motors?
DC Motor vendor has offered Class H insulation with temp rise to class F in place of Class F/B. Is vendor recommendation...
