An electric motor and a generator which is constituted using the electric motor as a power source and is used in an electric power line, characterized in that
- an electric drive generator is provided integrally or is provided separately,
- thereby a power generation function is obtained.
An electric motor and a generator which is constituted using the electric motor as a power source and is used in an electric power line, characterized in that
- in a case of a power generation function, the generator is activated and is risen up near to a synchronous speed and the generator is carried out a switch-on operation;
- in a case of an electric power generation function, the electric motor is made once in non-load condition and is activated and is risen up near once to a synchronous speed from a stop condition and the generator is carried out a switch-on operation;
- and
- thereby an induction motor excited on an electric power system line or an alternating current is constituted.
A fluid machine having a blade or a water turbine and a rotating machine, characterized in that
- in a case of a propelling machine, a twist angle is made reversal, and
- in a case of a centrifugal machine, an intake port of the fluid is changed over from an air inhale side to an air exhaust side;
- thereby without an alternation of a control circuit, a fluid transportation function is changed over to a power generation system.
An electric motor and a generator which is constituted using the electric motor as a power source and is used in an electric power line, characterized in that
- in every case of a power generation function and a complex function of the electric motor and the generator,
- when a stop or a power function is changed over to a power generation system, data necessary to control a load condition, an outside portion power condition, a power condition of an outside generator etc. are detected by a sensor;
- and
- in accordance with the detected data the stop or the power function is changed over to the power generation system, thereby a whole system is operation-controlled.
A wind power generation system having an electric motor and a generator for sending air using a blade and for carrying out a wind power generation by taking air into from all direction, characterized in that
- a wind direction guide is installed;
- and
- an induction motor is constituted as a main electric machine.
A wind power generation system having an electric motor and a generator for sending air using a blade and for carrying out a wind power generation, and having an electric motor and a generator, characterized in that
- an inclined magnetic field is formed in a flow passage using one selected from a single permanent magnet, a single electromagnet, plural permanent magnets and plural electromagnet;
- and
- air is moved always according to oxygen in the air and the inclined magnetic field.
A fluid power generation system having a fluid machine constituted by a blade, a water turbine and a rotating machine, and having an electric motor and a generator, characterized in that
- in a case of a single power generation function, the system is activated as the electric motor and the electric motor is risen up near to a synchronous speed;
- and
- in a case of a complex function of the electric motor and the generator, a rotation magnetic field is varied electrically, and the system is activated as the electric motor and the electric motor is risen up near to a synchronous speed.
A rotating machine having a stator and a rotor, characterized in that
- a single conductive member or plural conductive members are provided with a sandwich shape in a laminated iron core;
- and
- on an outer peripheral portion of the conductive member, a groove is provided to not flow current shortly between rotor bars.
A rotating machine having a stator and a rotor, characterized in that
- a single disc member or plural disc member are provided in a laminated iron core of the rotor;
- and
- the laminated iron core of the rotor is projected from an axial direction length of an iron core of the stator.
