Can a starter used for 5 hp 3 phase motor be used for 7.5 hp 3 phase motor?

No, you cannot use a starter rated for a 5 hp motor with a 7.5 hp motor. The starter needs to be matched to the motor's horsepower rating to ensure proper protection and operation. Using an undersized starter can lead to overheating and premature failure of the motor. It is recommended to use a starter specifically designed for a 7.5 hp motor.


How many watts dose a 5 hp 72 volt motor use in 20 minutes?

To determine the power consumption in watts of a 5 hp motor, you can use the conversion factor where 1 horsepower (hp) is approximately equal to 746 watts. Therefore, a 5 hp motor uses about 3,730 watts (5 hp x 746 watts/hp). If this motor runs continuously for 20 minutes, it will consume approximately 1,244 watt-hours (3,730 watts x 20/60 hours).


How much current will a 5 HP single phase 220 volt motor draw?

P=VI P=power V=voltage I=current therefore current drawn is 5000/400=50/4=12.5 amperes


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 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 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.


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.

30 amp 230 VAC circuit can you run a 5 hp motor?

This answer depends on the characteristics of the motor. There are may different applications for motors and though the HP remains the same, the full load amps differ. If you have the FLA of the 5 HP motor then an answer can be given.
