Vertical axis wind turbine technology continues to improve

1.3.3 A good vertical axis wind mill has to remain stable when it is spinning it. If not, the turbine will "shake its head" when the rotor is turning. That will reduce the turbine's life and cause other problems such as noise and mechanical wear. So the best solution is to use a coaxial structure for the wind mill and generator. The coaxial arrangement of wind mill and generator ensures ...

How to Choose a Servo Motor - Motion Control Tips

Correctly sizing a servo motor begins with knowing the load. This is also spoken of in terms of inertia. Generally speaking, the important figure is the inertia ratio, which is the ratio of the load inertia to the motor inertia, or Inertia Ratio = JL / JM where JL is the moment of inertia of the load and JM is the moment of inertia of the motor.
