Look at your amps and multiply by volts. This will give you watts.

ex.motor label 115V/14.4A 230V/7.2A

Whether you are running on 115v or 230v you get 1,656 watts.
This converts to 1.656 KW (kilowatts)
Your power company charges you by the KW hour. I'll use
12 cents per kilowatt hour for example.

\$0.12 x 1.656 = .1987
This rounds off to 20 cents per hour to run, so if you run the pump 6 hour a day,180 hours per month, the electrical cost would be

OK, I'll take a shot at this one:

You indicated that the present motor is a replacement. Does it match exactly the motor characteristics of the original motor? What was the prior amperage draw for the original motor?

Since you spoke in terms of "newtons of force" instead of torque, I assume you are not in the United States. You didn't specify the supply voltage but if it's in Europe somewhere, it should be around 220-230 volts or so.

At 5 horsepower and 746 watts per horsepower, the apparent power draw of the motor should be around 3,730 watts (5 x 746).

Assuming the motor has a standard power factor of around .85, the power consumption should be close to 3,170 watts (3,730 x .85). That equates to about 13.78 amps (3730w / 230v x .85) which is close to what you stated.

What to do? If you are familiar with power schemes, you could consider the installation of a "buck-boost" transformer to the circuit and increase the supply voltage. These specialty transformers come with different voltage taps to adjust the voltage output. However, you must be careful not to raise the voltage substantially or you will cause the stator windings of the motor to overheat. There can be voltage fluctuations on the power grid which can cause variations in power output and consumption. A buck-boost transformer can help to alleviate this issue.

This will require some re-wiring. Your local jurisdiction may have codes or other requirements governing specialty wiring devices.

Tip

IRobot Mirra 530 Tips & Tricks

Tips from iRobot Resources:

Run Mirra only when in the water.
Mirra has a very strong motor system that needs to stay cool for optimal performance and life. Your pool water around the motor helps keep it cool during operation. Therefore Mirra should not be run outside of the pool due to the risk of overheating the motor.

Choose the correct filter canister.
Use the Large Debris Filter Canisters when the pool contains a significant amount of large debris (leaves, insects, etc.) and when the pool is opened for the season or cleaning during the Fall. The Fine Filter Canisters are ideal for filtering small debris such as algae, sand, silt and bacteria and for regular pool cleaning maintenance during the peak of your pool season.

Keep Mirra working at peak performance.
Mirra uses the powerful force of water pumped through its filter to clean and circulate pool water and to propel itself around your pool. It pumps and filters more than a gallon of water every second! Clean the filter canisters regularly by removing them from Mirra, emptying its contents and hosing it out. Keeping the filter canisters clean will ensure optimal cleaning results and strong pump suction.

Allow the motor to cool before removing the robot from the pool.
Mirra's power supply has an automatic timer that shuts Mirra off after each cleaning cycle. Wait 20 minutes before removing Mirra from the pool to allow the pump motor to cool. Turn the power supply off and unplug it from the electrical outlet before removing Mirra from the pool.

How do I fix my fuel consumption problem

fuel consumption in stationary motors relies on the load on the motor, choke position and air filter cleanliness
a rated load on a gen set is considerable less than advertised power rate
that means that if you have a gen set bought at 5.5 kva, the continuous rating is actually 4.5 kva and anything more puts considerable load on the motor and increases the fuel consumption
the difference in the ratings is to allow for the extra surge required on electric motor start up
add up all the appliances that you have going at once and see ti it is close to max out put as that may be a start of you consumption problems

My motor for the usq1202 comes on and humms loudly, does not come on and then tripps the breaker. Is there a solution or do I need a new motor?

Could be a start capacitor, Ether in the back of the motor,about the size of a "D" cell battery, black with two or three wires coming from it. Or a little bigger in a case right on top of the motor.
With the power off remove this and go to get a new one at a pool store or a motor store. Take the old one with you as you will need to match it up to the new one.
It stores power to get the motor spinning. Otherwise the motor pulls to much power and kicks the breaker.
