Watts and horsepower are directly related as they are both measurements of power. 1hp = 745.6998 watts. So 3kW = 3000W / 745.6998 W/hp = 4.023hp You need a minimum of 4hp, which will give you a max of 2982W before any losses in your generator. You should probably go with a 4.5 or 5 horse motor.
What else can I help you with?
What generator size is needed for 0.5 hp 220 volt 1 phase?
The generator should be about ¾ hp.
What size generator is needed to run a 6HP compressor at 230V?
The electrical code book states that a single phase 3 HP motor at 230 volts draws 17 amps. This equates to 3910 watts. Allowing for starting inrush current a 5000 watt generator will run the motor but the generator will labor a bit until the motor gets up to speed. Generators with a higher wattage rating would have less trouble with the starting of the 3 horse power motor. <<>> One hp is 746 watts. 3*746=2238. It takes 3 to 6 times as much energy to start as it does to run.
Can you replace a three phase motor 3 Hp RPM 1420 with a single phase motor for a planer?
Probably not. The single phase three horse power motor will be much larger in physical size than its three phase counterpart, and will probably not fit.
What is the cable size for 600V 3 phase ac motor?
you need the current of motor or the KW/HP rating
What size motor do you need to run a compressor 2 stage 80 gallon tank i have a 3 phase on it and want to change motor?
You probably need a 5hp or 7hp motor. Look for HP rating o the 3 phase motor and select the same for single phase. 3 phase has same power but is more efficient at electricity use. Also consider a 3 phase converter. It allows a 3 phase motor to run on single phase service.
What generator size is needed for 0.5 hp 220 volt 1 phase?
The generator should be about ¾ hp.
What generator size is needed for 40 hp 480 volt 3 phase motor?
probably about 50 hp depending on how reliable the efficiency ratings of the various manufacturers are
What size diesel generator would you need if there was a power outage?
The size of the generator is based on the size of the load you want to supply. Size up the load in watts or amps along with what phase (single or three) and voltage that the load requires. These are needed to give a complete answer.
What size generator is needed to power this motor ES-31B Series Motor 90 HP Peak?
you need around 60000 watts on a dc current
What size of generator to run 5.5kw 400v 50Hz motor?
You need a 5.5kw generator to run a 5.5kw motor.
Concrete mixer whose motor got following configuration 5.5 KW 380v 1140 RPM 3 phase what is the suitable size of generator to run this motor?
You should get a 3 phase generator that has 8-12 KW. If you had to you could use a 3 phase 5.5-6 kw but it may wear out faster because you are using 100% power. The 3 phase gen will allow you to select 480 volt which can be converted to 380 for the mixer. The rpm of the motor in irrelevant because the generator is the power source in this situation, once the gen powers the motor it will produce 1140 to power the mixer.
What size generator would it take to start and run a 6 horsepower 220 volt electric motor on a air compressor?
To answer this question the full load amperage of the motor and what phase the motor is, should have been given. This answer uses the motor amperage give in the electrical code book and will be close for your purpose. A 6 HP is not a common size motor. 7.5 HP motor is 25.3 amps. Using a power factor of 90%. W = I x E x 1.73 x pf, W = 25.3 x 220 x 1.73 x .9 = 8666 watts. A 10kW three phase generator will probably start the motor if it is not under load when it starts. A 15 kw generator would be better. A single phase 7.5 HP motor draws 40 amps. W = I x E x pf = 40 x 220 x .9 = 7920. Again A 10kW single phase generator will probably start the motor if it is not under load when it starts. A 15 kw generator would be better.
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.
Will a 2800 watt generator run a 550 watt electric cement mixer motor?
Yes, a 2800 watt generator should be able to run a 550 watt electric cement mixer motor. The generator's wattage is more than enough to power the motor with some extra capacity for other devices. Be sure to check the starting wattage of the motor as well to ensure the generator can handle the initial surge of power needed.
What size diesel generator should I buy for a house this hurricane season?
The size of diesel generator varies greatly. The size that is needed would depend on the size of the house.
What size of wire to use for 1015 kva ac generator?
To answer this question a voltage must be given to find the current output. Also whether the generator is three phase or single phase.
What cable size is needed for 415VAC 3 Phase 400kVA generator to a load 50meters away?
As example, at 380V the generator produces 685A per phase. Therefore you will require 2 x 120mm2 cables per phase. (1 x 120mm2 cable will support 365A per phase). In total you will require approximately 1/2km of cable to cover the 50m run between the generator and the ATS panel/Load. i.e. 5 phases in total - 2 x 50m cables per phase.
