Field of the Invention The present invention relates to a device and a method for constructing a rotating electrical machine. [Prior Art] In various forms of rotating electrical machines, ^ is provided with a cylindrical casing which comprises a plurality of permanent magnets spaced apart around each other.哕聱 Ten oxygen. The mourning temple magnet is generally held in the casing by an electromagnetic box, which is complementary to the outer casing. However, ferrite-based magnets have recently been replaced with high-energy bismuth-based magnets. # By using a high-energy 鈥-based magnet, it is possible to increase the magnetic field strength (then (4) 仏(1) coffee (4) while reducing the size of the component. However, due to the magnetic strength of the basin, /, and the river, it is necessary to ensure A suggested way to hold the magnet in place in the cylindrical casing is to fix or fold the edge of the casing into engagement with the magnet 4, so that the magnet is closed. Between the two flanges thus formed on the outer casing 'However, such previous methods for forming such a device lead to cumbersome work, which is difficult for automation and requires two separate forming steps at two different workstations. SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide an improved and simplified apparatus and method for assembling a permanent magnet of a rotating electrical machine. It is a further object of the present invention to provide a permanent Improved method and apparatus for holding a magnet in place within a cylindrical housing that is versatile and can be used for different purposes The size of the outer casing. 83328 1275231 This rhyme ^ Ming Yi,,, ^ A feature is embodied in a machine for folding on the outer edge of the outer cylinder. The device includes a support tool for the outer casing. One of the pre-curved portions is angled with a final curved portion knife relative to a plane extending parallel to the branching device, and a driver. The actuator effectively causes the supporting device to move axially relative to the forming tool. Forming the forming fixture with the surrounding side (four) of the two outer casings disposed on the branching device. The driver simultaneously causes the supporting device to be in relative radial movement for determining the forming tool and the second supporting device. a portion of the upper peripheral edge of the outer casing that engages. Further, the drive pivots relative to the forming tool for engaging the peripheral edge of the supporting device on the peripheral edge of the TO nq fish " The surrounding part is curved. A control device operates the drive, and the first s ^ shun is pre-bent by the forming tool, surrounding a surrounding area. The peripheral edge of the placed outer casing is twisted to the ground, and then the final curved portion of the forming tool completes the bending operation. Another characteristic of the present invention is embodied as a magnet assembly for a motor. The method includes the following parts The outer portion of the outer casing is open at least partially radially inwardly from a radially extending end wall and is located in the extension portion. The plurality of magnetic portions are disposed within the cylindrical portion The surface is engaged, and the extension of the outer casing is bent toward the magnetic portion by contacting a forming tool, and the method is: and closed, a first end of the outer casing of the outer casing is formed to form a rotation to form a circle The other end of the cylinder is extended by the extension of the end wall from the open end of the cylinder, and the portion thereof is brought into engagement with the end wall to engage the outer periphery. The portion is in contact with the axially shaped tool 83328 I27523l around the circumference of the cylinder, and the shaft is relatively rotationally engaged. The part of the shaft rotates relative to each other and continues to bend and extend. Therefore, the extension portion is finally bent to be fixed to the magnetic portion by surrounding the cylindrical portion between the second portion of the forming tool and the outer casing and the forming fixture. [Embodiment] Starting from Figures 1 to 3, a device 11 is used in the method of the four corners 12 and the invention is embodied. The device 11 includes an end for supporting the floor. The columns 12 are on top of the straws X and 13 and are joined to each other at their lower ends by means of a cross member 14 for forming a solid frame of the device U. ^字—The cutting plate 15 is fixed to the (4) at the height of the 适 ,, and is used for the working piece of the cylindrical iron form, the shape of which is as shown in Fig. 4 is not indicated by the symbol 16 . Referring now to Figure 5, the working (iv) cylindrical outer casing portion 17, at its end, is at least partially closed by an end wall 18 extending inwardly. In a complete rotating electrical machine, the end wall 18 defines an opening 19 for passage of a shaft. The "cylinder inner surface 21 of the peripheral 17 is adapted to receive a plurality of spaced apart permanent magnets supported by any suitable type of magnet holder. The magnets and consumables are arranged to engage the inner surface 2 of the cylinder and support the lower end of the magnet on the end wall 18. A ledge 22 is formed at the upper end of the surface 21 and coextensive with the magnet and the upper end of the frame. A thinner peripheral flange 23 is formed on the outer casing 'and in the illustrated embodiment as a cylindrical portion" 83328 1275231 - this is the case, who reduces the device and rotates, The boring process is completed.
