Is the larger the motor power, the more powerful it is? The answer is: not necessarily.

A motor with a higher power does not necessarily mean it is more powerful, because the power of a motor depends not only on power but also on speed.

The power of a motor represents the work done per unit time. The greater the power, the more energy the motor converts per unit time, which theoretically leads to better power performance. However, in practical applications, the speed and momentum of a motor depend not only on the power, but also on other parameters, such as speed and torque. Speed represents the number of times work is done per unit time or the amount of effective power, while torque is the product of force and distance, representing the moment of inertia.

Therefore, the power of the motor depends not only on power, but also closely on speed and torque.

In addition, the greater the motor power, the higher the power consumption, which means that under the same conditions, high-power motors consume more energy. Therefore, when selecting a motor, factors such as power, speed, torque and efficiency should be considered comprehensively according to actual needs to obtain the best cost-effectiveness.

So how do we choose the motor with the best performance? It is both simple and complicated. The simple thing is that as long as we know whether our product needs a high-speed motor or a high-torque motor, the motor selection is easy; the complicated thing is that we don’t seem to know what kind of power performance our product wants, high speed? High torque? Adults said they don’t make choices, and they seem to want both.

Then, we can try to answer another question: is the motor used under heavy load or light load? After figuring out the load, we can allocate the speed and torque. The motor used in heavy load scenarios has large torque and low speed, while the motor used in light load scenarios can have a smaller torque.
