Which motor is superior in efficiency and the most extensively used of all types of electric motors?

Motor efficiency depends on the motor size and how much it is loaded. You get the best efficiency above 75% of the rated load for that motor. Note the table below:
Horsepower Standard Premium Efficiency Efficiency% Efficiency%
1 --- 78.0 --- 82.5
2 --- 78.5 --- 84.0
5 --- 84.0 --- 89.6
10 --- 84.0 --- 91.1
15 --- 87.5 --- 91.7
25 --- 90.2 --- 93.0
50 --- 91.7 --- 94.1
100 --- 91.7 --- 95.0
250 --- 94.1 --- 95.8

What is the efficiency of a 12 volt electric motor?
Efficiency of any electrical machine is maximum when the load on that machine is such that the variable loss ( copper loss) is equal to constant loss (eddy current loss, hysteresis etc).the same applies to dc machines too.
What are high efficiency motors?
The efficiency of a motor is the output power divided by the input power. The difference is the lost power which appears as heat usually. High-efficiency motors produce very little lost power. But they tend to be more massive and expensive to make, so that most motor designs have to compromise on efficiency.
Working principle of brushless dc motor?
Traction motors are used in electrically powered rail vehicles such as electric multiple units and electric locomotives, other electric vehicles such as electric milk floats, elevators, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems such as diesel-electric, electric hybrid vehicles and battery electric vehicles. Additionally, electric motors in other products (such as the main motor in a washing machine) are described as traction motors.
What is the difference in functions between generators and electric motors?
the electric motors are round and the generators are square and they are powered by the sunshine the generators blow bubbles and the electric motors blow somkey green gas!! this gas is deadly If you are able, perhaps you can answer this in a serious manner. If you don't know the answer, than please STFU!!
Is 100 horsepower electric motor a heat engine?
No. electric motors aren't heat engines.
Do motors have batteries?
No, electric motors do not have batteries.Most electric motors are powered from the AC power grid.Power tools and other portable devices using electric motors have batteries, but the electric motors in the tools and devices do not themselves have batteries.

Do plane wheels have electric motors?
NO it does not have motors
Which models manufactured by Lincoln use an electric motor?
All of Lincoln's motors are electric, as electric motors have always been their specialty. Lincoln began making electric motors in 1895 and joined Leeson Electric in 2006.

Do telephones telegraphs and electric motors all use electromagnets?
phones and electric motors definitely do!
Do air conditioners have magnet in them?
yes because they have electric motors in them. electric motors contain magnets.
What kind of products does the Electric Motor Warehouse sell?
The Electric Motor Warehouse sells pool pumps and motors; other pool accessories like fencing, steps, etc.; electric motors like bathroom fan motors, air compression motors, etc.; and specifically a large collection of Dayton electric motors, including furnace blower motors and pressure washer motors.

How does the internal combustion engine compare to external combustion or an electric engine in terms of efficiency?
Internal combustion engines are now operating at about 30-40 % efficiency with the application of computer controls and continues to get better all the time. I am not sure of the efficiency rating of external combustion or central combustion engines. I will make an attemp to find out. Note that these engines to my knowledge are only used by the military in torpedoes so I am not sure if there is any info available to the general public. I have seen electric motors up to 55% efficiency. I am not sure if there are more efficient motors out there but I would bet yes.
