  Generator for better high-quality electrical
  
  In order to produce high-quality electrical (voltage and frequency stability), then the generator should work on the play speed (rpm) according to certain factory recommendations. To be able to rotate, the generator must be connected with a machine that could be driving a motor fuel, water turbines, steam turbines, windmill, water mill, etc.. In order for power plants have maximum performance and efficiency, should be designed so that the engine and generator drive to work in an ideal play speed (peak speed) respectively. To achieve such an ideal situation, required the appropriate type of liaison with the speed ratio between the engine drive shaft with shaft generator. The comparison of the speed of the play there are 3 kinds:
  
  1. Play speed driving machine with swivel speed generator.
  For this situation, you can use a direct connection where the shaft drive engine is connected directly (coaxis) with shaft generator commonly used in motor gasoline portable generators. The second alternative, can be used direct-couple as used on lawn mower. The third alternative, you can use an indirect connection is PULLEY-belt system or a system of gear-chain or gear to gear system (the second diameter or the number of teeth PULLEY both got the same gear).
  2. Turn the engine speed is lower than the driving speed of generator circles.
  For this situation, the system is needed as a liaison multiplication cycle. If the play speed difference is not too far (more than 1: 3), can use a single multiplication system that is simple enough. The multiplication of these systems can be PULLEY-belt system consisting of a large PULLEY the shaft drive engines and a small PULLEY generator shafts connected by a belt. The second alternative, can be a gear-chain system consisting of a gear (sproket) of the engine drive shaft and a gear (sproket) small generator shafts connected by a chain. The third alternative, can be a gear to a gear system that consists of a large gear on the engine shaft drive and a small gear on the generator shafts intersect each other.
  If the speed difference is pretty much play (less than 1: 3), need to use multiplication system is a complicated story. For this purpose, can be used helical-type gear box as one of the widely used alternative. While WORM-type gear box can not be used for multiplication because the system is irreversibel (not reversible). Alternatively, can also be used PULLEY-belt system or a system of gear-story-story chain. The number of levels, depending on the total multiplication ratio (TMR) is required.
  3. Play speed driving engine speeds higher than around the generator.
  For this situation, reducing system required as a liaison rounds. If the play speed difference is not too far away (less than 3: 1), can be used single-reducing system that is simple enough. The system may be reducing PULLEY-belt system consisting of a small PULLEY the shaft drive engines and a large PULLEY the generator shaft which is connected by a belt. The second alternative, can be a gear-chain system consisting of a gear (sproket) small shaft drive engine and a gear (sproket) of the shaft generator is connected by a chain. The third alternative, can be a gear to a gear system that consists of a small gear on the engine drive shaft and a large gear on the generator shafts intersect each other.
  
  If the speed difference is pretty much play (more than 3: 1), reducing the system needs to use a fairly complicated story. For this purpose, can be used both gear boxes and helical-type WORM type as one of the widely used alternative. Alternatively, can also be used PULLEY-belt system or a system of gear-story-story chain. The number of levels, depending on the Total Reduction Ratio (TRR) is required.
  In most power plants, turn the engine speed is not the same drive with swivel speed generator. Therefore, one of the things that must be done in power system planning is to bridge the gap the play speed (rpm) between the ideal shaft with shaft turbine generators. For that, necessary to create design a system of reducing or multiplication system that functions mentranformasi ideal swivel shaft speed to the speed of an ideal turbine generator shaft without much loss of power. In principle, reducing system or multiplication system is all mechanical systems ranging from PULLEY or gear mounted on a turbine shaft and gear box (if any), until PULLEY or gear is mounted on the generator.
  Hope this information have benefits for you.

  Hi,
  My bid is for 5arts/7days/$50total for 750w/art. Please see my profile for credentials. By the way, I teach physics and math as well. I sent a partial sample of a paper I have submitted. Thanks Susan
