This electric motor is driven by an \u2018alternating current.\u2019 It is a type of electric current that periodically reverses direction and changes its magnitude continuously with time. This current is a contrast to direct current, or \u2018DC,\u2019 which flows only in one direction. From a simple electrical input signal, an AC motor can offer a comparably efficient method of producing mechanical energy.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"AC_Motor_Construction\"><\/span><span style=\"font-weight: 400;\">AC Motor Construction\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">To better understand the <\/span><span style=\"font-weight: 400;\">working principle of AC Motor<\/span><span style=\"font-weight: 400;\">, first, let\u2019s see what the components of an AC motor are.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">AC motors consist of a frame or yoke, stator, rotor, bearings, fan, shaft, and slip rings. The frame is used as an outer protecting cover that is used to protect against environmental conditions. The frame also acts as an outer periphery such that the inner parts can be easily housed. The stable state section of the equipment is the stator on which the stator winding is enclosed.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The rotor is the moving part that either moves clockwise or anti-clockwise depending upon the thrust impelled on it. The bearings provide proper friction for the rotor to run smoothly. A fan is employed to remove the unwanted heat that is gained during the running of the rotor. It is expelled out through the ventilation that is provided behind the machine. A shaft is provided to deliver the mechanical output as the rotor rotates. The slip rings are employed for a normal Ac machine where rotating armature stationary field winding is employed. In this situation, the slip rings allow the input alternating current to change continuously in the coils.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-13171\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_.jpg\" alt=\"Working Principle of AC Motor\" width=\"2447\" height=\"1500\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_.jpg 2447w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_-300x184.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_-1024x628.jpg 1024w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_-768x471.jpg 768w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_-1536x942.jpg 1536w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_-2048x1255.jpg 2048w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_-696x427.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_-1392x853.jpg 1392w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_-1068x655.jpg 1068w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/2.main_-1920x1177.jpg 1920w\" sizes=\"(max-width: 2447px) 100vw, 2447px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Working_Principle_of_AC_Motor\"><\/span><span style=\"font-weight: 400;\">Working Principle of AC Motor<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">To gain a basic understanding of how an AC motor exactly works, we need to know its key characteristic. An AC motor specifically runs on alternating current.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">An Alternating current or charge is one whose flow direction around a circuit is reversed at regular intervals. It also means that the voltage on an AC circuit changes periodically, whereas a DC circuit remains relatively constant.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Now, the AC motor relies on a device called an alternator to produce this alternating charge direction. It is a specialized type of electrical generator. When electricity is passed through a spinning shaft, the rotor, an electromagnetic field, or EMF is usually created in that generator. Meanwhile, the stator turns around itself or within a set of static wire coils. When the rotor turns concerning the stator, the resulting EMF switches direction or polarity at set points relative to the stator.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">It happens because it is created by a charged rotor turning on a fixed axis. As a result of switching polarity, the periodic reversal of the current direction in an AC motor happens at regular and predictable intervals. All of this can be compared with a piston or paddle which moves water around a ducting system. When the piston moves water in and out at a consistent speed, it in turn pushes the water back and forth through the conduit.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Although AC motor offers a simple design, like a magnetically driven copper wound stator and a rotor mechanism, it is a low-cost and high-efficiency mechanism used in a large variety of applications. Wherever electric appliances are utilized, AC motor has its applications from heavy industrial to household environments, no matter what types and categories it has.<\/span><\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-13173\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/4.-main.jpg\" alt=\"Working Principle of AC Motor\" width=\"1920\" height=\"1280\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/4.-main.jpg 1920w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/4.-main-300x200.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/4.-main-1024x683.jpg 1024w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/4.-main-768x512.jpg 768w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/4.-main-1536x1024.jpg 1536w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/4.-main-696x464.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/4.-main-1392x928.jpg 1392w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/4.-main-1068x712.jpg 1068w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><\/p>\n<p><em><strong>Read More on Linquip<\/strong><\/em><\/p>\n<ul>\n<li><strong><a title=\"Working Principle of Stepper Motor: The Only Guide You\u2019ll Ever Need\" href=\"https:\/\/www.linquip.com\/blog\/working-principle-of-stepper-motor\/\" target=\"_blank\" rel=\"noopener\"><span style=\"text-decoration: underline;\"><span style=\"font-size: 10pt;\">Working Principle of Stepper Motor: The Only Guide You\u2019ll Ever Need<\/span><\/span><\/a><\/strong><\/li>\n<li><a title=\"The Only Guide You\u2019ll Ever Need For The Working Principle of Induction Motor\" href=\"https:\/\/www.linquip.com\/blog\/the-only-guide-youll-ever-need-for-the-working-principle-of-induction-motor\/\" target=\"_blank\" rel=\"noopener\"><span style=\"text-decoration: underline;\"><span style=\"font-size: 10pt;\"><strong>The Only Guide You\u2019ll Ever Need For The Working Principle of Induction Motor<\/strong><\/span><\/span><\/a><\/li>\n<li><span style=\"text-decoration: underline;\"><span style=\"font-size: 10pt;\"><strong><a title=\"Your Guide To The Working Principle Of DC Motor\" href=\"https:\/\/www.linquip.com\/blog\/working-principle-of-dc-motor\/\" target=\"_blank\" rel=\"noopener\">Your Guide To The Working Principle Of DC Motor<\/a><\/strong><\/span><\/span><\/li>\n<li><span style=\"text-decoration: underline;\"><strong><span style=\"font-size: 10pt;\"><a title=\"AC Series Motor\" href=\"https:\/\/www.linquip.com\/blog\/ac-series-motor\/\" target=\"_blank\" rel=\"noopener\">AC Series Motor<\/a><\/span><\/strong><\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"AC_Motor_Advantages\"><\/span><span style=\"font-weight: 400;\">AC Motor Advantages<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">AC motors are a preferred source of supply due to the following reasons:<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Longevity<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">With only a few moving parts, AC motors have the potential to last for years.
