I want to buy a 55 kw AC electric motor. Now 55 kw = about 75 hp.On ebay i see AC motors for sale that say .55 kw. Is this the same? If not how many horsepower is this?
that is 100 times smaller motor than what you have in mind. 1HP=746W=0.746kW 0.55kW is about 3/4 HP
A 55 kw motor is a major motor. Usually this motor is only seen in industrial applications because of the amount of electricity it takes to run this. Even all electric homes only are wired for 25 kw worth of capacity at best. You would need 3-phase wiring and a multiple transformer pole out at the street to run this big motor. If you are looking for this to be used in an electric vehicle, they supply the huge quantity of electricity with huge quantities of batteries. Batteries can deliver a large amount of amps for a rather short period. In electric cars they use a huge inverter to change the DC battery power to AC power for the motor. But they also design the AC motors in electric vehicles to be run by batteries and to have regenerative braking, so the motor is a different design than you will find in a normal industrial AC motor. Like the other guy said, .55 kw is only 3/4 hp , the kind of motor they use to run a drill press or band saw.
