This figure shows a winding diagram of a 4-pole single-phase motor, in which the main winding 1 is a single-layer concentric winding consisting of two windings in each column, and the speed adjusting winding 2 shown by a dotted line is the main winding 1. The auxiliary winding 8 is wound concentrically and overlappingly so as to have the same polarity, and the auxiliary winding 8 is wound astride the adjacent main winding 1 and speed adjusting winding 2 so as to be electrically shifted by 90° from them. The main winding 1
, the speed adjusting winding 2 and the auxiliary winding 8 are connected as shown in FIG. A voltage is applied and the motor rotates at high speed, and terminals 0.

これらと電気的に９０°ずれるように巻装されている。The main winding 81 is a concentric main winding 8 consisting of two windings.
1B and the main winding 81b, which is omitted from the winding corresponding to the winding with the shortest pitch inside the main winding 81&, are arranged adjacent to each other alternately, and the speed adjusting winding 82 is located at the position where the winding is omitted. The groove is wrapped as shown by the dotted line. Auxiliary i-line 8
is wound across the main winding 81 and the speed adjusting winding 82 so as to be electrically offset by 90° from them.

低速で回転させることができる。This speed adjustment winding 82 is wound concentrically with the main winding 81b of every other pole at a short pitch, so that when it is alone, it acts as two poles with the same i polarity as the main winding atb. The combined magnetic field with the main winding 81b normally acts as a counter pole to the main winding 81B. As a result, the motor can be rotated at high speed by applying voltage to the main winding 81 alone, and can be rotated at low speed by applying voltage to the main winding 81 and speed adjustment winding 82 connected in series. .

ともできる。According to the embodiment, the main winding 81. Speed lol! Since the four-node winding winding and the auxiliary winding 8 are each wound in a single layer, the winding work can be easily performed using an automatic winding machine. Since it is only necessary to provide the number of counter electrodes, the number of steps required for the winding work can be reduced, and the number of parts such as the insulating sheet described in the conventional example can also be reduced.
