How To Build a Fan Speed Controller for Heatsink

In this article we analyze regarding a automatic fan speed regulator circuit for managing the temperature of a heatsink and from stopping the temperature to erach harmful stages.

Making a Toy using a Motor Circuit

The suggested motor toy circuit which functions an automatic forward reverse actuation employing a sequential delay timer circuit could be visualized in this article diagram:

How to Protect Motor from Overcurrent

Talking about the following drawn 12v motor current control schematics, the idea definitely seems to be right, nevertheless the circuit achievement particularly in the second diagram appears inaccurate.
Let's examine the diagrams one at a time:

Motor Soft Start Circuit Using PWM Technique

High wattage motors for example pump motors or other types of heavy commercial motors often pull out vast current during their initial power turn on, which in turn impacts the correlated fuses and switches adversely leading to these to either damage of or corrode overtime. In order to correct the situation a soft start circuit becomes highly important.
