The difference between 12v DC Motor and 24v Motor
Although right now there are similarities between a 12v DC Drive Chain engine and a 24 Volt Motor, there are also distinct differences. General, both these motors are made to perform nearly identically other than a 12-volt engine 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 knowing about the differences between 12v DC motors and 24 volt motors. Of course, by working with the professionals at METMotors, the design and manufacturing are managed by highly skilled engineers. As part of the buying process, a business representative can clarify in greater detail the information specific to the kind of motor you wish to purchase.
However, with regard to example, some of the important comparisons between a 12v DC motor and a 24 Volt Engine are provided below.
If 20 amps are necessary for a 12v DC electric motor to supply a particular mechanical power output, then only 10 amps would be needed by a 24 volt electric motor to achieve the same level of performance.
For a simple kind of DC motor, the rotation is at full speed on simply no load, with acceleration determined mainly by applied voltage. As a result, if 24 volts had been put on a 12v DC engine, it could cause some harm by running at twice the speed.
In most cases, a 12v DC motor will be comparable in price in comparison with a 24 volt 
electric motor for the same application. The primary reason is that the physical size of the engine can usually determine its power result.
Gleam difference among wiring for a 12-volt motor versus a 24 volt engine. For instance, at 24 volts, smaller sized wire can be used for delivering power effectively, whereas for 12 volts, twice how big is wire is required to provide the same amount of power.
