![]() ![]() ![]() Security, Operating Voltage, Operating Current, Heat Performance and the Volume of the Module. As a result, the rotate speed difference between two modules is 40-50RPM!Īs a conclusion, TB6612FNG and LV8406T are better than L298N in efficiency test.Ģ). For an instance, while the supply voltage is 9V, the data of L298N is,Īccording to the data, the voltage drop of L298N is 1.99V.Īnd the efficiency of L298N under 9V is I1 V/ (I2V1) = 59.24%, which was nothing like TB6612FNG and LV8406T (The efficiency of this two modules are 80%-90%, you can find the detailed data in appendix 1. The calculation formula of motor driver is: Pmotor driver=pmotor/ (pmotor driver+ Pmotor). Our motor’s nominal voltage is 6V, 155RPM±. ![]() In order to get the efficiency of the DC motor driver, we need to figure out the power of motors and the power of the whole circuit. ![]()
