ていた。 Conventionally, a large number of iron core motors have been used that use lap windings or wave windings having a plurality of armature windings. However, when conventional windings are used as they are in ironless motors, there are various drawbacks as will be explained based on the first and second figures. The first and second illustrations are expanded winding diagrams that can be considered when conventionally known wave-wound windings are employed in an ironless motor. Figure 1 shows that the field magnetic poles are 6.
FIG. 2 is an expanded winding diagram of a wave-wound armature with magnetic poles and consisting of five armature windings. The field magnetic poles 1 are magnetic poles 1-1, 1-2,... magnetized to N and S poles with an opening angle of 60 degrees.
..., 1-6. The commutator 3 has commutator pieces 3-1, 3- with an opening degree of 72 degrees (6/5 of the magnetic pole width).
It is composed of 2, 3-3, 3-4, and 3-5. The armature 2 is a cross-connected regular wave winding in which the opening angle of the conductor portion contributing to the generated torque of each armature winding is made equal to the magnetic pole width. Armature winding 2-1, 2-2,
2-3, 2-4, and 2-5 are arranged at equal pitches with an opening angle of 72 degrees (6/5 of the magnetic pole width) without overlapping each other. Each armature winding has a wave winding connection, and armature windings 2-1 and 2-3, 2-3 and 2-5, 2-5
The connections between and 2-2, 2-2 and 2-4, and 2-4 and 2-1 are commutator pieces 3-2, 3-4, and 3-, respectively.
1, 3-3, and 3-5. Brush 4-
1 and 4-2 are supplied with power from DC power supply positive and negative poles 5-1 and 5-2, respectively, and the opening angle is 180 degrees (3/1 of the magnetic pole width). In the illustrated related positions, electricity is applied in the direction of the arrow, torque is generated in each armature winding, and the armature 2 and commutator 3 become commutator motors rotating in the directions of arrows A and B, respectively. According to the embodiment shown in Figure 1, since the number of armature windings is small, the armature current switches at a rate of 10 times (excluding singular points) during one rotation, so the rectification characteristics are good. Not. This creates a counter-torque that reduces efficiency and starting torque. Furthermore, the number of armature windings that exist between the positive and negative electrodes of a DC power supply will be extremely small, making it impossible to use it as a high-voltage DC motor, increasing the number of sparks, and easily causing short-circuit accidents. The durability of will decrease. In order to eliminate the above-mentioned drawbacks, a case in which armature windings are constructed in multiple layers will be explained with reference to FIG. 2. FIG. 2 is an expanded winding diagram of a wave-wound armature with six field magnetic poles and 15 armature windings. The field pole 1 is exactly the same as that described in the first illustration. Commutator 7
is a commutator piece 7- with an opening angle of 24 degrees (2/5 of the magnetic pole width)
1, 7-2, . . . , 7-15. The armature 6 is a cross-connected regular triple wave winding in which the opening angle of the conductor portion contributing to the generated torque of each armature winding is made equal to the magnetic pole width. Armature winding 6-1, 6-
2, . . . , 6-15 are stacked in multiple layers at equal pitches with an opening angle of 24 degrees (2/5 of the magnetic pole width). Each armature winding is wave-wound connected, and armature windings 6-1 and 6-7, 6-7 and 6-13, 6-

The connection parts of 11 and 6-2 are connected to commutator pieces 7-
5, 7-11, 7-2, 7-8, and 7-14. Armature winding 6-3 and 6-9, 6-9
and 6-15, 6-15 and 6-6, 6-6 and 6-1
The connection parts of 2, 6-12 and 6-3 are commutator pieces 7-6, 7-12, 7-3, 7-9, 7-15, respectively.
It is connected to the. As mentioned above, there are three pairs of brushes because of triple wave winding, and brushes 4-1 and 4-2 are connected to DC power supply positive and negative electrodes 5-1 and 5-2, brushes 4-3,
4-4 is the DC power supply positive and negative poles 5-3, 5-4, and the brushes 4-5, 4-6 are DC power supply positive and negative poles 5-5, 5-
6, and the opening angle of each is 60 degrees (magnetic pole width). In the illustrated related positions, electricity is applied in the direction of the arrow, torque is generated in each armature winding, and the armature 6 and commutator 7 become commutator motors rotating in the directions of arrows A and B, respectively. According to the embodiment of FIG. 2, the thickness of the armature increases because the armature windings are superimposed in multiple layers. Such thickness has the disadvantage of significantly weakening the effective field poles passing through the armature, reducing efficiency and starting torque. For this reason, in the past, efforts have been made to reduce the thickness of the conductor portion that contributes to the generated torque. However, since this process is carried out by pressure molding or the like, many defective products such as armature winding breakage or short circuits occur. Furthermore, since the mutual positional relationship is not regulated when arranging the armature windings, the phase relationship tends to shift, making it extremely difficult to obtain a highly efficient DC motor, and the manufacturing process is also complicated, making it difficult to mass-produce. It was becoming expensive. In addition, in the method used for conventional ironless motors equipped with cylindrical armatures, insulated wires are wound one by one in an aligned manner to avoid overlapping the ends of the winding width, either by winding the entire winding width or by winding a part of it. The method used is to wind diagonally to the width of the winding, turn it back alternately at both ends every 180 degrees, and wind it continuously in order to form a cylindrical armature, but even in this case, it is not suitable for mass production and is expensive. It had become a thing.

第3図以下について説明する。 The present invention has the effect of eliminating the above-mentioned drawbacks, and making it possible to obtain a DC motor of this type that has a simple structure, is suitable for mass production, can be supplied at low cost, and has good efficiency. In other words, for a field magnetic pole having 2mn magnetic poles (m is an integer of 1 or more, n is an integer of 3 or more), m (2n±1) armature windings, and the electric machine during one rotation. The child current switches 2mn (2n±1) times (excluding singular points)
By providing a rectifying device for this purpose, the thickness of the armature can be made thin, and a DC motor with high torque, high efficiency, and good rectification characteristics can be obtained. In addition, according to the patent application announcement "Sho 44-4450", 4
field number ±1 for one or more field poles
Direct current motors are known which have two armature windings and twice the number of armature windings. When the field magnetic poles are 4 magnetic poles, it has a remarkable effect, but when the field magnetic poles are 6 or more magnetic poles, a commutator piece with twice the number of armature windings has a large amount of counter torque, which reduces efficiency and starting torque. The decrease is significant. The present invention has been made for field magnetic poles of six or more magnetic poles, and the details of the present invention apparatus having the above effects will now be described with reference to FIG. 3 and subsequent figures.

Reference numerals 53-3, 53-4, and 53-5 are position sensing elements, for example, Hall elements, induction coils, and the like. The opening angle of each is 72 degrees (6/5 of the magnetic pole width). Position detection elements 53-1, 53-2, 5
3-3, 53-4, and 53-5 are housed in a support body 47 shown in FIG. 16, and are opposed to the position detection band 46. When the position sensing element is a Hall element, the magnetic poles 50-1, 50 of the magnet rotor 50
-2, . . . , 50-6 leakage magnetic flux to the outside can be utilized. Symbol 54 is the shaded part 54-1,
54-3 and 54-5 are N poles, and the dot part 54-
2, 54-4, and 54-6 are the S poles, and correspond to the position detection band 46 shown in FIG. Hall element 53- when facing the S pole

The output makes the corresponding transistors of the second group included in the energization control circuit 52 conductive, and the armature winding corresponding to the DC power supply negative electrode 55-2 becomes conductive. The armature current is controlled by these conductions. That is, in the illustrated relative position, the Hall element 53-5 faces the S pole.
The output makes the corresponding transistor of the first group conductive, and connects the DC power supply positive electrode 55-1 and the armature winding 51-.

Therefore, current is applied in the direction of the arrow, and torque is generated in each armature winding, and the magnet rotor 50 and the position sensing band 54 rotate in the directions of arrows C and D, respectively. Thus, the switching of armature current during one rotation is 2mn (2n - 1) = 30

Since this energization method is the same as that of a commonly used semiconductor motor, the magnet rotor 50 and position detection band 54 form a semiconductor motor that rotates in the directions of arrows C and D. The above-described embodiment is a case in which the field magnetic poles are six magnetic poles and the number of armature windings is five, but other embodiments can be similarly applied to semiconductor motors.
