2. Induction generator - Wikipedia

   en.wikipedia.org/wiki/Induction_generator

   An induction generator produces electrical power when its rotor is turned faster than the synchronous speed. For a four-pole motor (two pairs of poles on stator) powered by a 60 Hz source, the synchronous speed is 1800 rotations per minute (rpm) and 1500 RPM powered at 50 Hz. The motor always turns slightly slower than the synchronous speed.

3. AC Propulsion eBox - Wikipedia

   Lateral view of the AC Propulsion eBox. AC Propulsion executives announced their intention to convert Scion xBs to battery electric vehicles in October, 2003. [1] Company executives stated that the Scion xB was chosen in part due to its boxy shape which allows for good placement and installation of a battery pack.

4. Doubly fed electric machine - Wikipedia

   en.wikipedia.org/wiki/Doubly_fed_electric_machine

   Doubly fed induction generator (DFIG), a generating principle widely used in wind turbines. It is based on an induction generator with a multiphase wound rotor and a multiphase slip ring assembly with brushes for access to the rotor windings. It is possible to avoid the multiphase slip ring assembly, but there are problems with efficiency, cost ...

5. Induction motor - Wikipedia

   en.wikipedia.org/wiki/Induction_motor

   A feature in the generator mode in parallel to the grid is that the rotor speed is higher than in the driving mode. Then active energy is being given to the grid. [2] Another disadvantage of the induction motor generator is that it consumes a significant magnetizing current I 0 = (20–35)%.

6. Permanent magnet synchronous generator - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet...

   A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.

7. Synchronous motor - Wikipedia

   en.wikipedia.org/wiki/Synchronous_motor

   The number of pole-pairs is 2, so the synchronous speed is: = = A three-phase, 12-pole (6-pole-pair) synchronous motor is operating at an AC supply frequency of 60 Hz. The number of pole-pairs is 6, so the synchronous speed is:
