i have to build a measurement system for measuring the statorwinding pf pmsm temperature based on raspberrypi .
the component are :
3 Phase Stator,Relay , Current Controller (ACS712) , raspberry pi zero and pico , temperatursensor,Analog-to-Digital Converter
could someone help me please?
i don´t understand how to control the stator from the relay . is it possible ? as far as i konw the pmsm have to be controlled by six step commutation based on an three phase inverter…
