    Synchronous Motors

    Thanks cloche for your input. You certainly know your stuff. Our plant has 12 ft. of head and the penstock is only 55 ft. long. We will examine all the hydro-dynamic parameters carefully and use closed loop control on anything that involves water flow. On a plant this size we can afford to go...

    Synchronous Motors

    Thanks guys; bigamp must be right, the motor has to be a wound rotor type rather than synchronous. It has 3 slip rings, and as alehman pointed out the rpm is 885, not 900. As for the reduction, I have the original flat belt drive. This motor was used to drive a tree chipper at a pulp mill in...

    Thanks jplinn. I don't know yet how quickly the turbine/generator will accelerate, but I plan to stop the water flow within 5 to 10 seconds of a load rejection. Is that fast enough? The rotor has a lot of inertia.

    Please indulge me, my knowledge in this area (motor design) is limited, my specialty is assembly machine design. There are brushes and 3 slip rings for excitation, but no generator. Primary volts 2300 at 180 A, 3PH. That I understand. Secondary rating is 625V and 575A. What will the...

    Thanks for your reply ScottyUK. I'm building a small hydro-electric project in northern Ontario and I got this motor for free. It was rewound 13,000 hrs. ago. I want to use it with a Kaplan turbine running at 330 rpm and the motor is running at 885 rpm. My question really is whether there...

    Synchronous Motors

    I would like to know if I can use an 800 HP synchronous motor as a hydro-electric generator (connected to the grid) If it's possible what are the advantages and dis-advantages? Thanks
