High-speed generator with tooth-coil winding, permanent magnets and new design of a stator magnetic core made from amorphous alloy
2018
In this paper a new topology of the stator magnetic core made from amorphous alloy is studied on example of high-speed electric machine with permanent magnets and a tooth-coil winding with 6 slots and 2 and 4 poles with a power of 5 kW and rotational speed of 60,000 rpm The methods of electric machines designing made from the amorphous alloy material are described with regard to technological features; its advantages and disadvantages are shown. A sequence of basic iterative steps is presented, taking into account the technological features of using amorphous alloy materials in high-speed machines with permanent magnets and a tooth-coil winding. Based on the results of theoretical studies, an experimental layout was created and its initial tests were carried out at a lower frequency.
