電気機械
Document Type and Number:
Japanese Patent JP5409380
Kind Code:
B2
Abstract:
The present invention relates to an electrical machine having a rotor, a stator, a rotating-field production device, and a pole-field production device. The rotor can rotate about a rotation axis which passes through opposed upper and lower portions of the rotor. The rotating-field production produces an essentially radial magnetic field which rotates about the rotation axis of the rotor. The pole-field production device produces a magnetic field of opposite polarity to the rotor on the upper and lower portions. In order to reduce the size of the electrical machine without reducing the power, the pole-field production device has at least one magnet.
