Title: Ilya Petrov: Innovator in Position Sensing and Electric Machine Technology
Introduction
Ilya Petrov is a notable inventor based in Lappeenranta, Finland. He has made significant contributions to the fields of position sensing and electric machine technology. With a total of 3 patents to his name, Petrov's work showcases his innovative approach to engineering challenges.
Latest Patents
One of Ilya Petrov's latest patents is a variable reluctance position sensor. This sensor includes a first element with magnetic sensor sections that have excitation coils, first detection coils, and second detection coils. The second element is moveable with respect to the first element, featuring a periodically meandering airgap surface. When an alternating signal is supplied to the excitation coils, the envelopes of alternating signals induced in the detection coils depend on the position of the second element, resulting in a phase shift between them. The design includes a specific number of magnetic sensor sections to compensate for unwanted effects caused by the ends of the first element.
Another significant patent involves the stator of an electric machine. This stator comprises a core structure and a winding with multiple stator coils, which are mechanically supported by the core. Each coil contains electrical conductors and a cooling tube for conducting cooling fluid. The cooling elements are designed to transfer heat caused by iron losses from the stator core to the cooling fluid, ensuring efficient operation of the electric machine.
