Start the principles of single-phase ac motor?

With single-phase capacitor motor:two winding single-phase motor,namely starting winding and running winding.Two windings in space are 90 degrees. On starting winding in series the capacity of a large capacitor,when running and starting windings acmotortrading.blogspot.com by single phase alternating current (ac),because of the capacitor With the starting winding of current on time than the running winding current advance Angle of 90 degrees,to reach the maximum value.Form both in time and space Same pulse magnetic field,make the air gap between the stator and the rotor produces a rotating magnetic field,pumps under the effect of rotating magnetic field,the motor rotor Generated induced current,current and rotating generator rotor and stator magnetic field interact to produce electromagnetic torque,motor rotation.
