Electrical knowledge for all

Here I explain how to design the control and power circuits of two pneumatic cylinders. Functioning When the start  push button is press, the valve v1  energise which causes the cylinder to extern right up to the position of s1 . When the limit switch s1  is reached, the coil y1  energise which helps to deactivate v1  and return the piston back to the position of s0  with the help of a spring.Once s0  is reach, another coil y2  is energise which helps to deactivate y1  for the sequence to loop automatically.You can watch the simulation video to see how it works.

Hello, on this page i will present the basic steps in rewinding an electric motor. It is an undeniable truth that electric motors(induction motors) are the most widely used machines in all industries around the world for driving conveyors, pumping of liquids or petroleum products in conduits especially in oil companies. Despite the maximum protection put in place by protective relays such as thermal overload relays, magnetic relays, circuit breakers etc, the windings of this motors are still subjected to destruction due to improper installation or other faults such as single phasing, or maybe not using the right protective device for protecting the motor, or not using a starting method where and when necessary. In case of any of the above mention scenarios, the motor will be damage and unusable. So a very "smart" option will be to go for another one right? but how long have you used this one you just got for "$1000"? how much profit has it generated for you to jus...
