Many friends don’t quite understand the relationship between the number of turns and speed of a motor, as well as the relationship between speed and voltage, but they are curious and hope they can figure it out. Vacuz will introduce it to you!

The number of turns of the motor has a close relationship with the rotation speed. The larger the number of turns, the greater the electromagnetic force and magnetic field intensity output by the motor, but the rotation speed will decrease. The fewer turns, the higher the speed. However, it should be noted that this relationship is not absolute, because the motor speed will also be affected by other factors, such as the motor’s voltage, current, load, etc.

The relationship between speed and voltage is not a simple linear relationship. In actual situations, there is a certain error between speed and voltage. This is due to the influence of the internal resistance, load, friction and other factors of the motor, especially when the load changes greatly. When, the relationship between speed and voltage is more complicated. At this point, experiments or models are needed to determine the exact relationship.

In practical applications, we need to determine the operating voltage of the motor according to specific conditions to achieve the required speed requirements. Generally speaking, excessive voltage will increase the load and energy consumption of the motor, causing the motor to overheat or even be damaged. If the voltage is too low, the motor will not work properly and the speed will drop or even stop.

Therefore, when selecting the operating voltage of the motor, it is necessary to comprehensively consider the design parameters, load requirements, energy consumption and other factors of the motor to determine the most appropriate voltage.
