The difference between 12v DC Motor and 24v Motor
Although right now there are similarities between a 12v DC electric motor and a 24 Volt Motor, there are also distinct differences. General, both of these motors are made to perform nearly identically with the exception that a 12-volt motor draws twice the existing from its 12-volt supply than what a 24-volt motor draws.
For a given mechanical load, the power supplied to both motors would be similar.
Key Comparisons
Understanding their similarities is simply as important as understanding about the differences among 12v DC motors and 24 volt motors. Of course, by dealing with the professionals at METMotors, the look and manufacturing are managed by very skilled engineers. As part of the buying procedure, a business representative can describe in greater details the information specific to the kind of motor you wish to purchase.
However, with regard to example, some of the key comparisons between a 12v DC motor and a 24 Volt Electric motor are provided below.
If 20 amps are necessary for a 12v DC motor to supply a specific mechanical power output, after that only 10 amps would be needed by a 24 volt motor to attain the same level of performance.
For a simple kind of DC engine, the rotation is at full speed on no load, with rate determined primarily by applied voltage. Consequently, if 24 
volts had been applied to a 12v DC electric motor, it could cause some harm by running at twice the speed.
Generally, a 12v DC motor will be comparable in price when compared to a 24 volt motor for the same application. The main reason is usually 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 engine. For instance, at 24 volts, smaller sized wire can be used for Transmission Chain delivering power efficiently, whereas for 12 volts, twice the size of wire is needed to provide the same quantity of power.
