Problems solved by technology

The structure is simple and easy to construct, but its main disadvantage is its low durability when it is already at a reasonably high rotational speed
The structure is therefore only suitable for low rotational speeds, usually below 3000rpm

Embodiment Construction

[0031] Fig. 1 shows a motor of the present invention, in which a shaft 1 rotating about a frame of the motor and a disc rotor 2 supported to the shaft are arranged, while viewing the rotor from the side. A stator 4 supported to the motor frame is arranged in the direction of the shaft 1 on the first side of the rotor 2 and includes a stator winding 3 . Between the rotor 2 and the stator 4 there is a small air gap 14, behind a corresponding air gap 15 on the other side of the rotor, the assembly conducting the magnetic flux is arranged, which in this embodiment is the rotor fixed relative to the frame Yoke 5. The rotor yoke 5 can be made of a suitable composite material, or it can be a helical laminate made of electrical steel sheets. The rotor frame plates 8 are made of work hardened rolled plate of a suitable aluminum or copper alloy.

[0032]In the second embodiment of FIG. 2 , the rotor 2 and the stator 4 are similar to the embodiment of FIG. 1 . Alternatively, the magne...

Abstract

The invention relates to an axial flux induction electrical machine comprising a frame, a shaft (1) bearing-mounted to the frame, a disc-like rotor (2) supported to the shaft, a stator (4) comprising a stator winding (3) and supported by the frame on the first side of the rotor in axial direction. The disc-like rotor (2) comprises a non-ferromagnetic rotor frame (8) fabricated of a material with high electrical conductivity and comprising a uniform inner periphery (9) and an outer periphery (10) and conductor bars (11) fabricated of the same material and galvanically connecting the peripheries (11), the conductor bars together with the inner and outer peripheries forming in addition to the rotor frame also the cage winding of the rotor. In addition, between the inner periphery and the outer periphery there is a plurality of ferromagnetic pieces (12) extending through the frame plate and being spaced apart from each other at an appropriate distance so that the radial conductor bars are appropriately located between the pieces. According to the invention, the disc-like rotor frame (8) comprises at least one circular plate machined of work-hardened metal sheet.

Description

technical field [0001] The invention relates to an axial flux induction machine as defined in the preamble of claim 1 . The invention is primarily investigated working as an electric motor, but different generator embodiments can also be discussed. Background technique [0002] Since the characteristics of induction motors are usually optimal when there are only a few poles (two, or up to four) in the motor, such axial flux motors are inherently not very suitable as high-speed induction motors. motor. However, since in a two-pole machine the end-winding configuration of the stator windings is not always a practical solution, a two-pole solution is generally not suitable for axial flux machines. Therefore, high-speed axial flux motors usually also have to be designed as at least a four-pole structure. In this case, the magnetic flux in the stator yoke and the motor current in the windings must flow tangentially through the inner and outer quarters of the motor without gene...
