Embodiment Construction

[0038] Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 12 .

[0039] The motor armature in the present invention includes a magnetic circuit component with one or more parts and a multi-phase winding with multiple coils (Figs. 2-12). Preferably, the magnetic circuit part is formed from iron powder based magnetic composite material by pressing, molding or machining.

[0040] In this regard, it is not desirable to use magnetic circuits made entirely of laminated materials. Indeed, the circulation of alternating magnetic fluxes in three dimensions creates eddy currents in the plates. However, it is possible to divide the magnetic circuit into several parts. The parts where the flux does not circulate in the plane (jaws, corners) will be magnetic composite, while the other parts where the flux circulates in the plane (yoke, base of the jaws) can optionally be made of laminated materials. Although the mechanical assemb...

Abstract

A magnetic circuit component having a plurality of claws arranged in a plurality of rows, with the base of each claw connected to a common yoke. A plurality of non-interlaced coils constituting a multi-phase winding are included, with the coils being wound around the bases of corresponding claws, and being distributed uniformly in the direction of motion.

Description

Background technique [0001] The invention relates to an electric machine. In particular, the present invention relates to a claw pole design for polyphase electric machines. [0002] Electric motors use a changing magnetic field to generate electrical current or mechanical force. When a motor is used to generate current, a magnetic field is passed over the coils, which induces the desired current in the coils. When a motor is used to generate a mechanical force, current is passed through a coil, which causes the coil to be attracted (or repelled) by an adjacent magnetic field, thereby producing the desired force. [0003] The foregoing principles are generally applied to rotating electric machines. For example, in a generator or alternator, a rotating element or rotor passes through a magnetic field intermittently generated by a stator having poles arranged around the direction of rotation to provide a magnetic field (which may be generated electromagnetically). Electric m...
