Knowledge of physics can always be used in our lives. Believe it or not, just in terms of circuits and machinery, many friends always sigh, why did not study physics well at the beginning, but now it is not too late, I want to know 24 volts How to calculate the power of DC motor, and want to know how to better the speed of Diabolo, then look down.
The calculation formula of the electric quantity: W = Q = PT = UIT, also need to know a quantity, current or known power.
The speed detection is very important, it is a necessary condition to improve the stability of the speed of the 24V DC motor , but the cost is not the main factor. The speed control is relatively stable. If high accuracy is required, the reliability is high, and the price is low, it is recommended to use the Hall type. Pulse speed sensor. The cost of this control system is mainly on the drive. The PWM control method is adopted. If it is done in batches, the closed-loop interface of the rotational speed is designed to directly receive the signal of the Hall element, and the cost is lower, so that the rotational speed control is more stable.
