Two-leg synchronous electrical machine with permanent magnet stimulation and transversal flux guidance e.g. for bicycle, has flux in both legs transferred between rotor and stator via air gap in machine center

摘要

The machine has permanent magnet stimulation in its external rotor (R) and transversal flux guidance. The magnetic flux in both legs is transferred between the rotor and the stator (S) via a common smooth cylindrical air gap in the center of the machine.
