Title:
ELECTRONICALLY COMMUTATED ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO2001047089
Kind Code:
A3
Abstract:
An electronically commutated electrical machine having a rotor (3) interacting with a stator (2) in the form of an armature or armature comprising insulated conductors (11) interleaved with cores of ferromagnetic material (7) passing between the conductors, the whole bonded together with resin to form a disc or discs or annular structure in one or more planes such that to a first approximation magnetic forces between rotor and stator are equal and opposite and therefore balance out, the stator being held at one or more of its side or edge parts which are not surrounded by, nor connected by a bearing to, parts of the rotor, with sufficient strength to resist magnetic and mechanical forces when in operation and having provision for cooling by means of conduction, convection or fluid flow and having connections (17) for an alternating current electrical supply, said current being generated by means of a communicating circuit comprising an electronic inverter or other known means.
