Abstract:
A CAPACITOR MOTOR COMPRISING A STATOR, A PHASE SPLITTING CAPACITOR AND A ROTOR IN WHICH THE STATOR CONSISTS OF A CORE AND MAIN AND AUXILIARY WINDINGS EXTENDING THEREAROUND. THE MAIN AND AUXILIARY WINDINGS ARE CONNECTED IN SERIES AND FURTHER THE CAPACITOR IS CONNECTED IN PARALLEL WITH THE AUXILIARY WINDING TO GENERATE A ROTATING MAGNETIC FIELD IN THE STATOR FOR ROTATING THE ROTOR.
Abstract:
A commutatorless type direct current (DC) motor which has a rotor made of permanent magnet. Stator windings are sequentially passed with a current of constant phase rotation and thereby the rotor is initiated to rotate. After starting, counter electromotive forces induced in the stator windings are used for detecting the rotation angle of the rotor. Adequate currents are thereby made to flow in the stator windings and a steady rotation of the rotor is continuously performed.
