The voltage a cross the terminals of a certain 3-phase machine is 400 <40 ͦ V whereas the current which is assumed to be into this machine is 55<-60 ͦ  Find the real and reactive powers consumed or delivered by this machine. What is the type of this machine

Here it is the equivalent circuit of and induction motor and it is per phase circuit my question is name for me the variable for example R1 is the winding resistance and so an the all variable and please show me a pic of the real machine with the variable for example for R1 happens because of the winding i need to see the winding in the real machine, please help me to understand well
