Patent ID: 8115443

Claim:
A PSC motor includes: a stator core; a rotor arranged in a rotation relationship with respect to the stator core; a first to eighth winding coil sets (L 1 , L 2 , L 3 , L 4 , L 5 , L 6 , L 7 , L 8 ) wound around the stator core; and a capacitor (C 1 ), wherein the motor has two kinds of configurations for 4-pole and 6-pole operation modes, respectively, wherein the configuration for the 4-pole mode comprises a primary winding and a secondary winding which is connected in series with the capacitor (C 1 ), and has two reversible operation directions, when operating at one direction, the primary winding including the first to fourth winding coil sets (L 1 , L 2 , L 3 , L 4 ), and the secondary winding including the fifth to the eighth winding coil sets (L 5 , L 6 , L 7 , L 8 ); and when operating at another direction, the primary winding including the fifth to the eighth winding coil sets (L 5 , L 6 , L 7 , L 8 ), and the secondary winding including the first to fourth winding coil sets (L 1 , L 2 , L 3 , L 4 ), and wherein the configuration for the 6-pole mode comprises a primary winding and a secondary winding which is connected in series with the capacitor (C 1 ), and has two reversible operation directions, when operating at one direction, the primary winding including the first, second, fifth and seventh winding coil sets (L 1 , L 2 , L 5 , L 7 ), and the secondary winding including the third, fourth, sixth and eighth winding coil sets (L 3 , L 4 , L 6 , L 8 ); and when operating at another direction, the primary winding including the third, fourth, sixth and eighth winding coil sets (L 3 , L 4 , L 6 , L 8 ), and the secondary winding including the first, second, fifth and seventh winding coil sets (L 1 , L 2 , L 5 , L 7 ).
