Since the conventional insertion / removal device of the cantilever type permanent magnet rotary electric machine is constructed as described above, the axial removal spaces La and Lb are shown in FIGS. In the case where an elevator hoist is used, there is a problem that the installation space of a plurality of adjacent elevators is widened, and the installation occupancy of the elevators in a building is increased. This was a major drawback for elevators installed in high-rise buildings and monument towers. 9 and FIG.
Is not only an expensive attachment / detachment device because it uses screw feed and guide rails, but also because the screw feed and guide rails are installed horizontally, a bending force is applied to the device. There is also a problem that a strong and more expensive device is required.

Furthermore, since the apparatus is installed horizontally, a fine adjustment device in the radial direction is required to equalize the magnetic attraction force in the radial direction of the gap, and there is a problem that the apparatus becomes more expensive and complicated. Next, in the device shown in FIG. 14, since insertion and removal are performed irrespective of the magnetized (magnetized) magnetic force, the conventional insertion and removal device has an advantage that it can be inserted and removed with a minimum insertion and removal space Lc. However, when the unit is removed as a unit and the state shown in FIG. 16 is obtained, it is very difficult to carry out the vehicle from the electric room of the building (since the rotor and the stator are integrated). There was a problem. Further, even when it is necessary to replace only the rotor or only the stator, the rotor and the stator cannot be separated on site.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and in particular, in order to minimize a plurality of elevator installation spaces in a high-rise building, FIG.
Even if the method shown in Fig. 4 is adopted, the magnetized (magnetized) rotor and stator can be inserted and removed in a minimum space in the hoisting machine installation room on the top floor of a high-rise building. It is an object of the present invention to use a guide and a feed device in a vertical direction that does not deviate from the above, and to minimize the strength of the guide and to provide an inexpensive structure. It is another object of the present invention to provide an inexpensive insertion / removal device in which the positioning of the rotor and the stator is performed by in-row fitting to eliminate the need for a centering adjustment device.
