What is Servo Motor and its different types?

Image
A servo motor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration. In simpler terms, it is a small effective motor that is used in some serious applications that involve precise position control.  A servo motor is controlled by sending an electoral pulse of variable width or pulse width modulation (PWM). Different types of Servo Motor There are two types of servo motor namely; AC and DC servo motors. 1- AC Servo Motor They incorporate encoders that are used with controllers for providing feedback and closed_ loop control. Because they can be controlled, high accuracy can be maintained in regard to the application it is being required for. It has two further divisions that are a two_ phase AC and a three _phase AC. The two_ phase AC servo motor is used for low power applications. The three _phase is utilized for applications where a high power system is required (the current in this type of

What is a Limit Switch and How does it Work?

Image
Limit Switch is a type of sensor that identifies presence and absence. The limit switch can be mounted into remote locations so that it is moved by an object aside from using a human operator. How does a Limit Switch Work? 1- Limit switches have many functions, including the following:  2- Detecting the presence or absence 3- Identifies the range of movement and counting 4- Detecting the positioning & travel limit 5- Breaking a live circuit in case of the apparent unsafe condition 6- Detecting the speed Different Uses of limit switch The use of limit switch can either activate (turn on) or deactivate (turn off) an electrical circuit. Most limit switches are used in industrial companies and household appliances. 1- Use of limit switch in Industrial companies  In industrial companies, limit switches to shut off when an action exceeds its travel or position. An example would be when a robot malfunction occurred- the limit switch will shut down the power to the m

What is Flow Sensor & its Applications?

Image
Have your heard of a flow sensor before? If your answer is no, do not worry; you will become acquainted with what is flow sensor. Also, you will become acquainted with the applications of flow sensors. Now, let’s slow our pace a bit; it will be good to have an overview of what a flow sensor is all about before exploring flow sensor applications. Actually, it takes a proper understanding of what the flow sensor is all about in order to know its applications. A simple definition of a flow sensor is this: a device that is used to measure the flow rate of fluids (gas or liquid). You may have assumed that a flow sensor measures only the flow rate of liquids because you thought the term “fluid” applies to liquids alone. Well, if flow sensor was a principle or device in the biological science, then, you may be right. But, a flow sensor is a device whose origin is in the physical sciences particularly physics, or an applied science like engineering. In physics, fluid can mean either liqui

What are the uses and types of Limit Switch?

Image
You’ve probably heard of the term ’limit switch’’ if your work deals with electrical machinery. It is a piece of electromagnetic equipment that has an actuator having a series of contacts. It regulates machine operations having moving parts with a connection to a switching action mechanism. The contacts permit the limit switch to sense the presence or absence of an object or material. Based on the detection of contact defects, an actuator is moved by the sensor that changes the condition of an electrical circuit. This movement shows that some set ‘limit’ has been achieved. Domestically, limit switches are used in the home. Imagine these simple applications: 1- What makes the microwave stop whenever you open its door before the timer ends? 2- Alternatively, what keeps it from starting before shutting the door? 3- What makes the washing machine stop when the load is unbalanced? 4- Why does the dome lights in your car light up when you open the door? 5- What turns the light of

What are the advantages and disadvantages of Human Machine Interface?

A human machine interface is any software or device that aids a person/operator to interact with a machine, device or system. With the world having changed through constant growth in technology and innovations, machines have become more sophisticated. Human Machine Interface (HMIs) has also been improved greatly so as to enhance easier interaction with the constant - new technology. HMIs can be found in multiple locations or applications be it in Automobiles, household appliances, handheld devices (smart watches, smartphones), machines, video games and a very wide range of applications in the industrial sector. Advantages of Human Machine Interface The advantages of Human Machine Interface are:  1- Improved Productivity A human machine interface improves the efficiency of a task that is being performed. Even though a person can perform a task, this kind of software/device enables more productivity. In an industry, using an HMI enables more work to be done in lesser time.

What are the applications of Limit Switch?

Image
This is a switch that is operated by the motion of a machine part. They are used to detect the presence of an object when it reaches a selected or desired point.  It is an electromechanical device that consists of an actuator which is mechanically linked to a set of contacts. The limit switch regulates the electrical circuit that controls the machines moving parts by preventing the travel of an object past a predetermined point in the mechanism. The switch activates when an object makes contact with the actuator and by doing so either breaks or forms an electoral connection. Most limit switches fall under two categories: 1- Maintained Contact Switch It means that when it is switched on, it stays on until you push it off (labeled On-Off-On). 2- Momentary Contact Switch It means that when you push on, it stays on while still pressing/holding on it but upon releasing its springs back to its maintained position (labeled On (or Off). How does a limit switch work? The switch

What are the different types and components of PLC?

Image
PLCs stand for Programmable logic controllers and are digital computers for automating electromechanical processes such as lighting fixtures, control of machinery at the factory assembly lines or amusement rides. They are used in many machines and automotive and other industries. They are majorly designed for multiple outputs and input arrangements, elevated temperature range, noise immunity and vibration, and impact immunity. They are lightweight, rugged devices functioning without air conditioning, fans or electrical filtering. Different Components of Programmable Logic Controller There are three major PLC components , these are: 1. Processor 2. Power Supply 3. Input/output (I/O) section 1- The Processor The processor acts as the intellect of the PLC system. It’s a solid-state device designed to perform many functions in machine tool, process control function and machine tool. Formerly, relays, convectional electromechanically devices and associated wiring executed
