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 would be the efficiency to convert 12 volt to 5 volt?
It can be done with 90% efficiency.
Can you run a 12 volt ac water pump with a 12 volt dc adapter?
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
What is the efficiency of a 240 volt single phase 3 horse power motor which draws 12 amps under full load?
This might be a homework question, in which case you find the power, which is 3 x 746 watts, and divide by the voltage to find the current taken if the efficiency is 100%, and that is 9.325 amps. So the efficiency is 9.325/12 or 77.7%. In practice the question is complicated by the power factor of the motor, which means that the watts taken are less than the volts times amps. The power factor could well be 0.777, in which case the efficiency would be 100%.
What is the wattage rating of a Somfy 12 volt motor model no ct32-rt-12?
Motor: 12v AMP usage: 1.2amp Watt: 12x1.2=14.4W
What is a Variable 0 - 12V dc power supply?
A variable power supply has a control to adjust the DC output voltage from 0 to 12 volts. It is used for testing electric project's such as amplifiers and other electric devices. It can be used to replace other fixed voltages power supplies such as the srandard 3 volt, 5 volt, 9 volt and 12 volt units.
Which motor is used for fan drivers?
....on an automobile it is a 12 volt DC motor. the electric cooling fan is driven from this type motor.....
What would be the efficiency to convert 12 volt to 5 volt?
It can be done with 90% efficiency.
What size wire do you need for 20 amp 220 volt electric motor?
12 AWG in most circumstances.
How many kw can a 12 volt motor generate?
It depends on the current rating of the armature winding, which will determine its input power. It's output power then depends on the motor's efficiency.
Are auto electric systems 12 volt or 120 volt?
12 Volts DC
Can you run a 12 volt ac water pump with a 12 volt dc adapter?
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
Can the battery system of an electric vehicle 72V to 80V 468 Ah - Type - DC series wound - Power - 1218 Kw be used to power a 12 volt motor via cable for short periods?
If a single 12 volt source as in 2,6 volt batteries wired in sequence or one 12 volt battery can be isolated from the system it is possible.
Can a integrated circuit chip of nine volt supply used with 12 volt motor and work properly while using with bettaryof 12 volt?
no
Why not put a 12 volt motor to replace the 120 volt motor in your freezer Will this work?
The voltage of 120 volts is more common that the lower voltage of 12 volts.
What would cause a 12 volt motor to change polairity?
This assumes you have a 12 volt direct motor. You should be able to simply reverse the wires leading to the terminals. There should be two wires going to the motor. Change them around.
Does any one know if this 1967 mercury 500 50hp thunderbolt outboard motor is a 6 volt or 12 volt?
The Thunderbolt ignition is a 12 volt system.
How many watt of 220 volt will get by convering inverter from 200 Watt 12 volt?
Probably about 180 watts, assuming 90% efficiency.
