Additional to increase component, bearing, rotor and stator are all that motor itself is existing, simply by optimization stator winding, increase and draw
Conducting wire produces unique anti-gravity excitation winding structure, and existing motor is made to become a huge anti-gravity bearing and one more
Good zero-g inertial flywheel, and cost only have magnetic suspension bearing some thousandths of, this be exactly the utility model it is ingenious it
Place.When motor needs to make in electric motor mode or generator mode, by the switch unit in anti-gravity control module, to anti-
The lead of gravity excitation winding switches over, and anti-gravity excitation winding is recovered immediately to the stator winding of motor or generator
In.
Further, the utility model also has a variety of operating conditions, and therefore, flexibility is extremely strong.
In conclusion the serial power water pump of the utility model is easy to implement, structure is simple.Flexible operation, using energy source
Rate is high, is suitble to promote and apply.
