Abstract

PROBLEM TO BE SOLVED: To provide a stator which is capable of high output by materializing the high-density winding and the space saving of a winding end. SOLUTION: This stator possesses windings 3 and 4, which are connected in parallel in each unit of magnetic pole teeth of an iron core 1, and an insulator 2 which insulates the stator iron core 1 from the windings 3 and 4, and is equipped with a barrier rib 5 which isolates the fellow windings in each unit of the magnetic pole teeth. Hereby, the windings 3 and 4 can be wound, drawn up individually within the winding space made by the barrier rib 5 of the insulator 2d, so that the necessity to bundle the fellow copper windings is eliminated, and a high-density winding and space saving of the winding end become possible.

Description of the Related Art In recent years, there has been an increasing need to increase the density of windings and to save space at the ends of windings in order to reduce the size and improve the performance of motors. In particular, servo motors used in robots and the like use permanent magnets with extremely high magnetic flux density for the rotor of the motor, and use stator windings in order to respond to speeding up, space saving and high output of the robot. It is necessary to increase the density.

However, in order to realize a high output by using a permanent magnet having the same high magnetic flux density in the conventional configuration, it is necessary to increase the sectional area of the winding and to flow a large current. . However, in order to wind a single copper wire around the pole teeth of an iron core, the copper wire was too thick to be wound easily and was difficult to align. Also, if the copper wire is cut in half and the two are bundled together and rolled, this time, each copper wire will be twisted and cannot be aligned and rolled. In either case,
There was a problem that it was not possible to save the space between the high-density winding and the winding end.
