This is very curious! It should be the case that a bit over 3000 should give you 50 hz at low load for a 2 pole motor. So say 3100 or something like. Where 83Hz comes from I have no idea! I could understand 100. My only suggestion is that either you have a faulty frequency meter / rev counter or the...

Water power is undoubtedly one of the best forms of renewable energy, usually constant and easily controllable....the only problem is of course the limited number of sites where it is viable. In the UK there are several thousand sites where small hydro has been used in the past and many others where...

just to agree with paul. On any switch the voltage rating given is always the maximum safe and lower will be fine. You would definitely need a relay. I have recently been quoted a price on the MES DEA pump of £180 plus VAT. I would say it was the only price I got from them, still waiting on the p...

With plans for a new EV project taking shape I wonder if anyone can share experiences of buying stuff from the USA. I have found a number of companies such as Electric Motorsport and EVparts amongst others with interesting equipment and well priced kit. Im not after anyone dishing the dirt on the in...

The contacts are light so you will need a relay to operate the motor of the pump. RS Stock No. 289-5513 Manufacturer Norgren Manufacturer...

without wanting to teach anyone to suck eggs :D if the the motor is 2 pole (will haver a plate rating of approx 2800 rpm) it will need to be driven at 3000 a to get 50 hz (50hz=50rps=3000rpm) for the 4 pole motor (nominal speed on the plate 1440 rpm ish) then 1500rpm for generator. The plate speed i...
