Travelling field synchronous ac motor |
摘要 |
The invention relates to a synchronous AC electric motor with concentrated windings (2), whereby one primary side pole is comprised of a series of toothed-modules (4) with each toothed-module (4) being connected in the correct electrical phase sequence to a corresponding phase (11) of the motor electrical supply (5). In order to provide a highly optimised concentrated winding motor design applicable equally to either linear or rotating machines, which retains the performance benefits of existing concentrated-winding motors it is proposed that neighbouring modules (4) are wound so as to have alternating polarities, whereby the number of toothed-modules (4) comprising a primary side pole is exactly equal to twice the number of motor phases (5), and that the motor is designed to operate using an air-gap flux component which is a harmonic of the fundamental phase current frequency. <IMAGE>
