The difference between 12v DC Motor and 24v Motor
Although there are similarities between a 12v DC motor and a 24 Volt Motor, there are also distinct differences. General, both of these motors are designed to perform almost identically with the exception that a 12-volt engine draws twice the existing from its 12-volt supply than what a 24-volt motor draws.
For confirmed mechanical load, the energy supplied to both motors would be 
similar.
Key Comparisons
Understanding their similarities is just as important as knowing about the differences among 12v DC motors and 24 volt motors. Of course, by dealing with the experts at METMotors, the look and manufacturing are taken care of by very skilled engineers. As part of the buying procedure, a company representative can clarify in greater fine detail the info specific to the kind of motor you intend to purchase.
However, with regard to example, some of the important comparisons between a 12v DC motor and a 24 Volt Motor are provided below.
If 20 amps are required for a 12v DC Auto Chain electric motor to supply a specific mechanical power output, then only 10 amps will be needed by a 24 volt electric motor to achieve the same level of performance.
For a simple kind of DC electric motor, the rotation reaches full speed on no load, with quickness determined primarily by applied voltage. Consequently, if 24 volts had been applied to a 12v DC electric motor, it might cause some harm by running at twice the speed.
Generally, a 12v DC electric motor will be comparable in price when compared to a 24 volt motor for the same application. The main reason is certainly that the physical size of the engine can usually determine its power output.
There is also a difference among wiring for a 12-volt motor pitched against a 24 volt engine. For example, at 24 volts, smaller wire can be utilized for delivering power effectively, whereas for 12 volts, twice the size of wire is needed to provide the same quantity of power.
