Summary:Each of the devices for fastening the magnets in the slots is designed as a prismatic housing (7) surrounding the magnets, whose end faces, as well as the walls of the shaft and stator sides, are designed from non-ferromagnetic material. Those lying on the poles are designed from ferromagnetic material. The housings are fastened in the rotor slot with separable connections whose corresponding elements are mounted on the rotor and housing ends so that the housings can be located and can be slid out of the grooves in the axial direction. The electrical machine has an annular stator (1) with the winding mounted on the periphery and a cylindrical rotor (2) with the nonmagnetic shaft (3) , with the ferromagnetic segment-shaped poles (4) distributed on the periphery. These form the non- magnetic intervening space in the form of the slots running parallel to the shaft axis. There are the prismatic permanent magnets (6) located in the afore-mentioned slots and the device for fastening the magnets in the slots.
