The difference between 12v DC Motor and 24v Motor
Although presently there are similarities between a 12v DC electric motor and a 24 Volt Motor, there are also distinct differences. Overall, both these motors are designed to perform almost identically with the exception that a 12-volt electric motor draws twice the current from its 12-volt supply than just what a 24-volt motor draws.
For confirmed mechanical load, the power supplied to both motors would be similar.
Key Comparisons
Understanding their similarities is simply as important as knowing about the differences among 12v DC motors and 24 volt motors. Of course, by working with the experts at METMotors, the look and manufacturing are dealt with by very skilled engineers. As part of the buying process, a organization representative can explain in greater fine detail the information specific to the type of motor you intend to purchase.
However, for the sake of example, a few of the essential comparisons between a 12v DC motor and a 24 Volt Motor are provided below.
If 20 amps are required for a 12v DC engine to supply a specific mechanical power output, then only 10 amps will 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 velocity determined primarily by applied voltage. Therefore, if 24 volts were applied to a 12v DC electric motor, it could cause some damage by running at two times the speed.
In most cases, a 12v DC motor will be similar 
in price when compared to a 24 volt motor for the same application. The main Stainless Steel Chain reason is definitely that the physical size of the motor can generally determine its power result.
There is also a difference between wiring for a 12-volt motor versus a 24 volt motor. For example, at 24 volts, smaller wire can be utilized for delivering power efficiently, whereas for 12 volts, twice the size of wire is required to provide the same quantity of power.
