Some mechanical mills sported speed control provided by hinged blades that folded back in high winds reducing the thrust, by reducing the rotor capture area. When steel blades where introduced they required a reduction gear to compensate for their high speed, so that the standard reciprocal pumps were at the right speed for the mill to function ...

A turbine's rotor diameter, or the width of the circle swept by the rotating blades (the dotted circles in the second illustration), has also grown over the years. Back in 2010, no turbines in the United States employed rotors that were 115 meters (380 feet) in diameter or larger. In 2020, 91% of newly installed turbines featured such rotors.
A Synchronous motor is a type of AC motor that runs at a constant speed. And before discussing the speed control methods of a Synchronous motor, let us see how to find the speed of a synchronous motor. Using this simple formula: Ns = (120xf) / p, we can calculate the synchronous speed of any synchronous motor. Let's look at this formula in more detail.

Beater mills are high-speed comminution machines often found in lignite power plants for final stage comminution of lignite. The basic operational idea is to break the feed particles with the use of a high energy collision instead of a low-energy high-force crush as found in their counterparts – ball mills ( Silva and Casali, 2015 ).
