The difference Transmission Chain 
between 12v DC Motor and 24v Motor
Although generally there are similarities between a 12v DC electric motor and a 24 Volt Motor, there are also distinct differences. Overall, both these motors are created to perform almost identically with the exception that a 12-volt motor draws twice the current from its 12-volt supply than what a 24-volt motor draws.
For confirmed mechanical load, the power supplied to both motors will be similar.
Key Comparisons
Understanding their similarities is just as important as understanding about the differences between 12v DC motors and 24 volt motors. Of course, by dealing with the experts at METMotors, the look and manufacturing are handled by very skilled engineers. As part of the buying process, a company representative can explain in greater detail the information specific to the kind of motor you wish to purchase.
However, for the sake of example, some of the important comparisons between a 12v DC motor and a 24 Volt Electric motor are provided below.
If 20 amps are necessary for a 12v DC engine to supply a particular mechanical power output, then only 10 amps would be needed by a 24 volt engine to attain the same level of performance.
For a simple type of DC electric motor, the rotation reaches full speed on simply no load, with speed determined mainly by applied voltage. For that reason, if 24 volts were applied to a 12v DC electric motor, it might cause some damage by running at two times the speed.
In most cases, a 12v DC electric motor will be similar in price in comparison with a 24 volt engine for the same application. The main reason is that the physical size of the electric motor can usually determine its power output.
Gleam difference between wiring for a 12-volt motor versus a 24 volt motor. For example, at 24 volts, smaller sized wire can be utilized for delivering power efficiently, whereas for 12 volts, twice the size of wire is required to provide the same amount of power.
