Claims

[Claims for Utility Model Registration] The stator winding of the single-phase induction motor M of the conde laser start operation type, which is directly connected to the compressor and housed in the frame, is the first winding M1, and the stator winding is the first winding M1. The second winding M2 has a small reactance and the third winding M3 has a large coil reactance.
The external terminals Ult V1?
The terminal U1 of the first winding M1 connects the first switch 1, which is turned on when the load is low, and the third switch 3, which is turned on when the load is low, with the terminal U1 of the first winding M1 connected to U2=V2=U39v3 in an airtight manner. Through each, one end is one L of the bus bar
A second switch 2 is connected to the other end terminal of the capacitor C connected to 1, and is turned on at 5QHz high load.
and the fourth switch 4, which is turned on when the load is high, are connected to the other bus bar L2 through the terminal V of the first winding M□.
1 is connected to the other bus line L2 via the first switch 1.
and one of the busbars via the fourth switch 4, and the second busbar. The terminal U2 of the winding M2 is connected to the terminal 1 through the second switch 2 and the third switch 3, respectively, and the terminal 2 of the second winding M2 is connected to the bus bar through the second switch 2. The terminal U3 of the third winding M3 is connected to the other bus bar L2 via the third switch 3, and the terminal U3 of the third winding M3 is connected to the other bus bar L2 via the operating switch 5 or directly. On the other hand, the terminal 3 of the third winding M3 is connected between the first switch 1 and the third switch 3.
and connected to one side □ of the bus bar, respectively, and
Connected to the other end terminal of the capacitor C via the second switch 2 and the fourth switch 4, respectively.
