Can a starter used for 5 hp 3 phase motor be used for 7.5 hp 3 phase motor?
No.
Minimum breaker size 60 horsepower motor?
Need motor voltage, amperage and phase to give you an anwer.
What size power cord for a 30 hp motor 480 volts?
To answer this question, wire size is rated in the amount of amperage that it can legally carry. The formula to find amperage when the HP is known is I = HP x 746/1.73 x E x %eff x pf. A standard motor's efficiency between 5 to 100 HP is .84 to .91. A standard motor's power factor between 10 to 100 HP is .86 to .92. Amps = 30 x 746 = 22380 = 22380/ 1.73 x 480 x .87 x .87 = 22380/629 = 35.6 amps. The electrical code states that a motor conductor has to be rated at 125% of the motors full load amperage. 35.6 x 125% = 44.5 A #8 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 50 and 55 amps respectively.
What size wire do you need for a 240 volt 3 hp well pump that is 400ft from power source?
To answer this question accurately the amperage of the motor must be given. Using 746 watt equals one horsepower will not be as accurate but will be close to the correct wire size. The equation for amps when HP is known is I = HP x 746/E x %eff x pf. Amps = 746 x 3 = 2238/240 x .84 x .86 = 2238/173 = 13 amps. A standard motor's efficiency between 5 to 100 HP is .84 to .91. A standard motor's power factor between 10 to 100 HP is .86 to .92. A #8 copper conductor will limit the voltage drop to 3% or less when supplying 13 amps for 400 feet on a 240 volt system. The electrical code book states that a 3 HP motor on 230 volts draws 17 amps. If this is closer to what you pump draws then the wire size will be; A #6 copper conductor will limit the voltage drop to 3% or less when supplying 17 amps for 400 feet on a 240 volt system.
How many watts of power does a 5 horsepower motor use?
A single-phase induction motor uses variable amounts of current depending on the load etc. but on a 240 v system you should allow 7 amps per horsepower, so 35 amps for 5 HP.
What size electric motor is needed to replace 220cc petrol?
It depends on the horse-power of the engine. 220 cc would be about 8-10 HP, equivalent to a 6-8 HP electric motor. But a small petrol engine is usually not used at full power continuously, so manybe a 5 HP motor would do the job.
Which capacity of solar cells will be required to run 2 hp electric motor for pumping water from 250 ft deep tube well size of pipe inside the well is 3 inches and outer size of the pipe is 5 inch?
If the electric motor requires 2 hp to run, then you need to supply it with no less than 1,492 watts of electric power. It makes no difference what job the motor is used for.
What size generator do you need to move a 30 hp electric motor?
A 5 kW generator would turn it over but if the full 30 hp of mechanical power is needed, that would require about 30 kW of electric power from the generator.
How big of an electric outboard motor is required for a 10 foot fishing boat?
The right size for an electric outboard motor for a 10 foot fishing boat seems to be 4 - 5 - 6 hp, 8 - 9.9 hp or 15 - 20hp. It simply depends on what kind of fishing boat it is.
Does a 5 hp electric motor draw less amperage if it is not doing 5 hp of work?
All motors draw less current when their load reduces.
What size outboard motor should a 13 foot boat have?
5-10 hp gas motor should be more than adequate. An electric motor would alos work well, especially on small lakes or sloughs without significant current.
What size breaker for a 5 hp table saw motor?
20 amp should do ya.
How much does it cost to run a 5 hp electric motor for 1 hour drawing 15 amps per line?
$1
How can i construct a 3 phase 5 hp electric motor?
Best advice I can give is 'Buy one' you have not even specified what rpm you require.
How many hp in a 190 cc motor?
190 cc. is about 5 hp.
What is the flow of 5 hp motar pump?
The flow of 5 hp motor pump is around 90 GPM.
Can a starter used for 5 hp 3 phase motor be used for 7.5 hp 3 phase motor?
No.
