The difference between the stepper motor and DC motor, I just started to contact the intelligent tracking car, is not driven by DC motor and stepper motor L298N, is not? There are several DC motor, it is two, this is my new
Some of the values, driven by certain beats.), small step motors can use the ULN2003 driver, and the working current of DC motor is much larger, generally small DC motor with special L298N this kind of driver control, when using SCM to output PWM wave control.
The control method has the difference, the step motor control is similar to the digital circuit, needs to have the rhythm (similar to the digital tube display, the monolithic integrated circuit cycle parallel output
Stepper motor and DC motor in the motor in completely belong to different types, as long as the DC motor voltage will be coupled with the right turn, but turn laps difficult to precisely control; and the stepper motor according to the rhythm of work, can rotate the minimum angle (0.1 degrees)
