DC motor testing at no load
DC motor testing at no load
(OP)
If I have an unloaded 1500 HP 700 VDC shunt wound motor how can I determine the voltage and current levels, starting from 0 volts and ramping up, that it would take to first get the motor to roll that run at full base speed. I know that to get to full base speed I will need 700 VDC and full field but what would be the armature current to account for windage and friction?
I know that this is a some what simple question that deals with a more complex situation.
Thanks in advance.

RE: DC motor testing at no load
1500 HP is around 1 MW. 1% of 1 MW is 10 kW, which translates into around 14 A. So, I would expect anything between 10 and 30 A. There are so many unknown factors that one cannot guess any better. At least not me.
