आप वीएफडी के साथ एकल चरण मोटर का उपयोग नहीं कर सकते, यह संधारित्र को नुकसान पहुंचाएगा!!! YOU CANNOT USE A SINGLE PHASE MOTOR WITH A VFD, IT WILL DAMAGE THE CAPACITOR!!!
An induction motor is slipping all of the time away from the applied AC frequency. (a synchronous motor maintains RPM based on applied Frequency). If you apply more and more load to any motor the load amps go up until it reaches a "Locked rotor amps" condition if it is not protected properly . Look up "Speed no load" @@ajarivas72
