Crawling in induction motor (definition, analyzing and overcome)
Crawling in induction motor Crawling in induction motor … previously we talk about cogging in induction motor and know that the induction motor fails to start rotation … in this article I will explain the crawling phenomenon and how to overcome this phenomenon. Firstly, I want to explain some definitions that we will need to understand [...]
Cogging in induction motor (definition, reasons and how to reduce)
Cogging in induction motor Cogging in induction motor … Today we will explain important phenomena that occurred in induction motors called cogging (or magnetic locking phenomena or teeth locking phenomena) … before we talking about how to overcome cogging or magnetic locking phenomena in induction motor we should know [...]
Ac series motor (Principle, Types, Characteristics and Applications)
Ac series motor Ac series motor or the universal motor is an electric motor which operates in either Ac or Dc power at the same speed and output. Also Ac series motor is a modified Dc series motor!! What does this mean; it means that we modify the Dc series motor to be able to work in Ac single phase supply as: We laminate the [...]
Efficiency of induction motor-losses of induction motor
Efficiency of induction motor-losses of induction motor Losses of induction motor: To talk about losses of induction motor we talk about constant(fixed) losses and variable losses: Constant (fixed) losses: From the name, fixed losses remain constant over the normal working range of the motor; We can determine these losses by [...]
Circle diagram of induction motor (Simple steps to learn Circle diagram)
Circle diagram of induction motor To understand the circle diagram of induction motor we should first know what is the circle diagram; The circle diagram is a graphic representation of the performance of the machine and it’s drawn in terms of the locus of the input voltage and current. And it’s based on the [...]
Torque slip characteristics of induction motor (full guide)
Torque slip characteristics of induction motor Torque slip characteristics of induction motor also known as torque-speed characteristics provide us with the information about the variation of torque with the slip. And the variation of the slip obtained with the variation of speed; When the speed varies the slip vary and in [...]
Equivalent circuit of induction motor (for 3 phase and single phase)
Equivalent circuit of induction motor The Equivalent circuit of induction motor … We have repeated over and over that we use the induction motor everywhere in the industrial and domestic applications and that makes it very important to predict the behavior of the induction machine under various operating conditions. With [...]
Types of single phase induction motor (Split phase, Capacitor start, …etc)
Types of single phase induction motor Types of single phase induction motor aren’t new to your ears. When we talk about induction motor we illustrated that the single phase motor can classify into many types. Depending on what we classify this motor it’s the most important. Later we said that the single phase induction motor [...]
Induction motor-types of induction motor - parts and principle
Induction motor Induction motor or asynchronous motor is one of the most commonly used types of electrical (alternating current) motors which runs at a speed less than its synchronous speed. This motor doesn’t have brushes or commutator which makes it powerful and efficient. It’s used in many applications as [...]
Geothermal power plant (Sources, History, Diagram and types)
Geothermal power plant It’s not the first time to hear about geothermal power plant as we illustrate in types of power plants that geothermal plant is the station where we use (geothermal energy) hydrothermal resources to produce electricity and this plant requires high temperature (300ᵒF to 700ᵒF). Geo (earth) and [...]
