In this tutorial I will show you how I've made my first version of this brushed DC motor speed controller. Please have in mind in the video I had some errors that I've fiexed in the final schematic. The controller has PWM control with 3 MOSFETs in parallel for more power and heat dissipation. It ... view more

What’s up my friends welcome back. Today we will look at a very basic circuit but also quite interesting. If you are into electronics I bet that you’ve heard about inverters. We have the rectifiers that pass AC voltage to DC voltage and then we have the inverters that will pass DC voltage to ... view more

Full theory from electronics-tutorials.ws. One of the main reasons that we use alternating AC voltages and currents in our homes and workplace’s is that AC supplies can be easily generated at a convenient voltage, transformed (hence the name transformer) into much higher voltages and then ... view more

If you ever opened a power supply of some sort, you might have seen a special component. That is a transformer but used in a FLYBACK configuration or sometimes called a coupled inductor. You will also notice that the transformer doesn’t have just one input and one output as common transformers ... view more

In this tutorial we will see how to control one axis but using BRUSHED DC MOTORS. Usually CNC axis will move using stepper motors in an open loop control. Here we will see an example of close loop control with an optic encoder as feedback. Why do this? well, for bigger motors, the price of steppe... view more
