motor, also known as an asynchronous motor, is an AC electric motor that is commonly used in society. <\/span><span style=\"vertical-align: inherit;\">So called because these devices operate at a speed less than their synchronous speed.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Then, the need for electric current in the rotor to produce torque is obtained through the electromagnetic induction phase from the rotating magnetic field in the stator winding. <\/span><span style=\"vertical-align: inherit;\">Then what exactly is the definition of an induction motor according to the branch of electrical engineering?<\/span><\/span><\/p>\n<h2><span style=\"vertical-align: inherit;\"><span style=\"vertical-align:

title=\"\"><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">From an electronics construction perspective, the definition of an induction motor is the simplest electric machine that operates using the principle of induction in which an electromagnetic field is induced into the rotor when the magnetic field rotates.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Technically it can also be said that an induction motor is a type of AC electric motor (reversing) which has a rotor rotation that is not the same as the rotation in the stator field \/ has a difference in rotation (slip).<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Induction motors are also durable in use. <\/span><span style=\"vertical-align: inherit;\">This makes it the ideal machine for a wide variety of activities. <\/span><span style=\"vertical-align: inherit;\">In fact, it can be operated for years without requiring periodic maintenance.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">On the other hand, the speed of an induction motor is relatively static, so it cannot be applied to devices that require dynamic speed. <\/span><span style=\"vertical-align: inherit;\">Moreover, the speed control was somewhat difficult. <\/span><span style=\"vertical-align: inherit;\">In addition, the initial use of input current is high enough to trigger a more rapid reduction in voltage.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Induction engines are among the most common types of motors used in commercial, industrial, or household settings. <\/span><span style=\"vertical-align: inherit;\">This device has the following characteristics.<\/span><\/span><\/p>\n<p><strong><span

style=\"vertical-align: inherit;\">In theory it is stated that when the Stator on an induction motor is supplied with electric voltage, an electric current will automatically flow in the stator coil and the result is a magnetic field wave rotating around the stator.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">a. <\/span><span style=\"vertical-align: inherit;\">So the formula for the speed of the stator rotating field in the induction motor is Ns = 120.f \/ p:<\/span><\/span><\/p>\n<p><img decoding=\"async\"

inherit;\"><span style=\"vertical-align: inherit;\">Types of Induction Motors<\/span><\/span><\/h2>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Induction motors are often classified based on their rotor construction. <\/span><span style=\"vertical-align: inherit;\">On this basis, there are at least two types that need to be known, namely as follows.<\/span><\/span><\/p>\n<ul>\n<li><strong>Wound rotor<\/strong><\/li>\n<\/ul>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">The wound rotor is designed to have a coil connected to the star on the inside, while the other end is arranged in the form of a slipring towards the outer resistance. <\/span><span style=\"vertical-align: inherit;\">The coil can later be developed so that its speed keeps up with the rotation of the motor.<\/span><\/span><\/p>\n<ul>\n<li><strong>Squirrel cage<\/strong><\/li>\n<\/ul>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Located on the inside, this rotor is the free-spinning part of the machine. <\/span><span style=\"vertical-align: inherit;\">Usually made using laminated iron material where the stem has a short connected slot at each end.<\/span><\/span><\/p>\n<h3><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">3 Phase

style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">In a three-phase system, there are three single-phase channels with a phase difference of 120\u00b0. <\/span><span style=\"vertical-align: inherit;\">So the rotation of the magnetic field has the same phase difference where the whole will drive the rotor to move.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">If you consider the three phases a, b, and c, when phase a is magnetized, the rotor will move towards phase a of coil a. <\/span><span style=\"vertical-align: inherit;\">Next, phase b will be magnetized so that it immediately attracts the rotor, and then phase c. <\/span><span style=\"vertical-align: inherit;\">With this mechanism, the rotor can continue to rotate.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Examples of the application of 3-phase induction motors include elevators, large-capacity exhaust fans, oil extraction plants, textile industries, and the like.<\/span><\/span><\/p>\n<h3><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Single Phase Induction Motor<\/span><\/span><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-3391\"

title=\"\"><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">In this type of motor, the starting coil may have a series capacitor and\/or a centrifugal switch. <\/span><span style=\"vertical-align: inherit;\">When the supply voltage is applied, the current in the main coil lags the supply voltage due to impedance. <\/span><span style=\"vertical-align: inherit;\">Meanwhile, the current in the starting coil experiences a supply voltage according to the impedance of the starting mechanism.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">The angle between the two coils is sufficient to produce a phase difference to drive the rotating magnetic field so as to produce a torque. <\/span><span style=\"vertical-align: inherit;\">When the motor speed has reached 70 percent to 80 percent of the total synchronous speed, the centrifugal switch opens, disconnecting the starting coil.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Examples of the application of single phase induction motors include compressors, mixers, toys, pumps, high-speed vacuum cleaners, electric shavers, and drilling machines.<\/span><\/span><\/p>\n<h2><span style=\"vertical-align: inherit;\"><span style=\"vertical-align:

href=\"https:\/\/matob.web.id\/random\/technology\/what-is-induction-motor-and-how-it-work\/\">induction motor<\/a> is as a medium for converting electrical energy into magnetic induction power so that it can produce mechanical motion.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">There are basically two types of induction motors where the classification is arranged based on the input supply. <\/span><span style=\"vertical-align: inherit;\">There are single-phase and 3-phase induction motors, each of which has different applications, as previously discussed.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">But in essence, the type of single phase induction machine is not a motor that can start operating alone, while a 3 phase induction motor works the other way around, it can start operating alone.<\/span><\/span><\/p>\n<h2><span style=\"vertical-align:

name implies. <\/span><span style=\"vertical-align: inherit;\">When you provide supply to the stator winding a magnetic flux will be generated in the stator due to the current flowing in the coil. <\/span><span style=\"vertical-align: inherit;\">At the same time, the rotor windings are arranged so that each coil is short-circuited.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Furthermore, the flux from the stator will cut the short circuit coils in the rotor. <\/span><span style=\"vertical-align: inherit;\">Since the rotor coil is set to short circuit, according to Faraday&#8217;s law of electromagnetic induction, current will begin to flow through it. <\/span><span style=\"vertical-align: inherit;\">Parallel to this, another flux will be produced in the rotor.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">There are now two fluxes, one is the stator flux, and the rest is the rotor flux. <\/span><span style=\"vertical-align: inherit;\">The rotor flux will lag with respect to the stator flux. <\/span><span style=\"vertical-align: inherit;\">Therefore, the rotor will feel a torque that can make it rotate in the direction of the rotating magnetic field.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Examples of tools that use induction motor applications are easy to find in everyday life, both in the industrial sector and meeting household needs.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">This device offers a number of advantages, such as relatively cheap price, high level
