Improving the power factor of an electrical installation consists of giving it the means to produce a certain proportion of the reactive energy it consumes itself by installing capacitors or capacitor banks. Power factor is the ratio of working power to apparent power. It measures how effectively electrical power is being used.
Curious about laser level? Watch the demo and Learn How To Use Laser Levels. In surveying and construction, the laser level is a control tool consisting of a laser beam projector. The tool is leveled according to the accuracy of the device and projects a fixed red or green beam about the horizontal and/or vertical axis.
A lead screw usually has a longer pitch and smoother surface, resulting in much higher efficiency. Also because of the longer pitch, higher linear speeds are obtained. All you need to know is a lead screw is best for anything non structural. Trade off between Threaded Rod & Lead Screws is cost and availability.
Curious to learn about PLA aka Poly Lactic Acid use in biodegradable plastics. Watch me explore the world of plastics and polymers by making a few basic plastics from biological sources I've collected before, and with the help of the Center for Sustainable Polymers at the University of Minnesota.
Curious about what is Hall Effect and how Hall Effect Sensors work. The Hall Effect is the most common method of measuring magnetic field and the Hall Effect sensors are very popular and have many contemporary applications.
Given two batteries, it chooses the one to connect to the load based on the voltage measured at their poles. It can also be used to switch DC power supplies. The circuit we are proposing is an automatic battery switch made with power MOSFETs with very low RdsON, which are specifically for SMD.
Every machinist needs to know, but that is confusing and often misunderstood: How to calculate speeds and feeds. Learn Formulas and step-by-step method for doing the calculations with an explanation and animations. Every curious student, machine operator or machinist should watch this video.
In this video I will conduct a small experiment in order to show you whether the DC, BLDC or Stepper Motor is best suited as a generator. Along the way we will learn a bit about the theory of those motors and realize why a gearbox can be an important part of a generator setup. Let's get started!
In this video I will show you my technique when it comes to THT and SMD soldering tasks. I show you with some practical examples how easy it is to solder and what kind of tools and materials are necessary to do the job.
