Hi
I want to measure 3 phase AC motor connected to VFD and measure Voltage and Amps in all 3 phases and motor position I want to use high speed sampling to realise the voltage curve every single degree of the motors spin for a couple of seconds.
Can I use 3 red pitaya boards together
Is the data time synced then
I build this controller http://www.instructables.com/id/200kW-A ... ctric-Car/
measure 3 phase AC motors current , voltage and position

Re: measure 3 phase AC motors current , voltage and position
Hi,
You can use one Red Pitaya for current measurements and
on Red Pitaya for voltage measurements.
In this case you have 4 inputs.
2 inputs for currents, current in the 3 phase can be calculated since I1+I2+I3 = 0
2 inputs for voltages, voltage in the 3 phase can be calculated also V1+V2+V3= 0
Inputs on the Red Pitaya are synchronized
and also you can synchronize two or more Red Pitayas trough external trigger mode.
Best, RP
