摘要： Disclosed are foil coil structures and methods for winding the same for stators in electrodynamic machines, as well as electrodynamic machines that implement such coil structures. In one embodiment, a foil coil structure is configured for implementation with a field pole member having pole faces that confront, for example, conical magnets.

摘要： A method for off-line testing of an electric motor is disclosed. The motor having at least one stator winding, and a rotor arranged along a rotation axis. The method includes applying a periodic test signal to the at least one stator winding; collecting first measuring data, related to a physical quantity of the at least one stator winding while the rotor is being rotated about the rotation axis, from one or more waveform periods of the test signal, detecting first peak values of the first measuring data; forming second measuring data based on the first detected peak values, detecting second peak values of the second measuring data for the at least one stator winding; determining a mutual relationship between the at least a portion of the second peak values; and, providing, if the mutual relationship deviates from a predetermined relationship, a signal indicating a fault in the rotor. Also disclosed is an apparatus for performing the disclosed methods.

摘要： 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 a 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 form in addition to the rotor frame also the cage winding of the rotor. 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 ferromagnetic piece (12) has a surface plate (5, 15) on the surface against the stator, the resistivity of this surface plate being essentially higher than the resistivity of the ferromagnetic piece.
