An efficient slip ringless synchronous machine is provided. A magnetic field pole portion 8 projects in the d-axis direction and a transformer magnetic path portion 9 projects in the q-axis direction on the outer periphery of the rotor core 4, and a field coil 7 is disposed on the magnetic pole portion 8 in a transformer magnetic path portion. A secondary coil 6 is wound around 9. The high-frequency voltage induced in the secondary coil 6 is rectified by a rectifier circuit (not shown) and supplied to the field coil 7. The motor of the present invention is excellent in reliability because it is non-contact power feeding despite the fact that the rotor has a field time coil. [Selection] Figure 1 |
