An inner stator of a drum type motor is disclosed. In a conventional inner stator punched by silicon steel piece is exploded into an inner stator ring with a plurality of inlaying groove, inner stator teeth and exciting coil wire seats. The wire seat is wound by a respective exciting coil and then is engaged with a stator teeth, which is correspondent to the outer ring of the inner stator ring with respect to the plurality of inner stator ring unit. The guide pin of the wire seat is positioned and combined with the upper and lower exciting coil retaining plate, and the wire head and tail of the coil is welded to the upper and lower retaining plates so as to be serially connected as a complete exciting coil. Therefore, a motor inner stator is formed.

DETAILED DESCRIPTION In the winding engineering in the prior art motor, if the winding is arranged linearly, more space is occupied, and the motor operates effectively, while the whole cost is too high.
Another, the production in winding is very low so that the cost of each motor is increased.
This is not suitable in mass production.
In the inner stator of a drum type motor of the present invention, the guide pins in a CNC machine operation for arranging linearly winding exciting coil used in the prior art is not used so that the cost in the winding machine is reduced and the production efficiency is increased.
In the inner stator of a drum type motor of the present invention, the root ends of the stator wire grooves are separated from the outer ring of the inner stator with an equal angle, while the width of the separate distal end is not large than the root end.
A pair of correspondent jointing ends are formed at the distal end and the outer ring.
Therefore, the insulating wire seat of the inner stator root ends can be formed in advance.
The winding is performed by a roller type winding machine so that the cost is low and production efficiency is high.
Moreover, the winding machine of the winding transformers can wind exciting coils on an insulating wire seat in a high rotary speed by a coaxial multiple winding way.
This means that the winding efficiency can be greatly increased.
In the whole, in the present invention, the technology for manufacturing a transformer by a coaxial multiple winding way can be used in the present invention.
Moreover, a drum type outer rotor motor with a high operation efficiency and high mechanical strength can be manufactured in the present invention.
To achieve the aforesaid object, the present invention provides an inner stator 10 of a directly driving drum type motor, wherein a conventional inner stator punched by silicon steel piece is exploded into an inner stator ring 211 with a plurality of inlaying groove, inner stator teeth 31 and exciting coil wire seats 41
