hello to all,
hope all r fine.
motor specifications are 230 V ,Y connected ,15000 rpm ,125 W BLDC
Which parameter(Current or speed) i have to take reference for
checking output & for calculating efficiency.
In which manner i have to check & test.
1.For 15000 rpm(as reference) how much is current & voltage.
2.for .384amp. current how much is speed, vlotage & power.
as P=V*I
so i=125/230xsqurt(2)
rms voltage=230xsqurt(2)
I want to know difference of BLDC & PMSM.
please tell me about this.
