DC motors take electrical power through direct current and convert this energy into the mechanical rotation.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">DC motors include two key components: a stator and a rotor. In a DC motor, the stator provides a rotating magnetic field that drives the rotor to rotate.<\/span><\/p>\n<p><span style=\"font-weight: 400\">A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the center of the coil. One or more windings of insulated wire are wrapped around the core of the motor to concentrate the magnetic field.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-6406\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/03\/AC-Motor2.jpg\" alt=\"\" width=\"560\" height=\"560\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/03\/AC-Motor2.jpg 1500w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/03\/AC-Motor2-300x300.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/03\/AC-Motor2-1024x1024.jpg 1024w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/03\/AC-Motor2-150x150.jpg 150w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/03\/AC-Motor2-768x768.jpg 768w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/03\/AC-Motor2-696x696.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/03\/AC-Motor2-1392x1392.jpg 1392w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/03\/AC-Motor2-1068x1068.jpg 1068w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/03\/AC-Motor2-420x420.jpg 420w\" sizes=\"(max-width: 560px) 100vw, 560px\" \/><\/p>\n<div class=\"su-box su-box-style-default\" id=\"\" style=\"border-color:#00021e;border-radius:3px;max-width:none\"><div class=\"su-box-title\" style=\"background-color:#263551;color:#89cabd;border-top-left-radius:1px;border-top-right-radius:1px\">Read More on Linquip<\/div><div class=\"su-box-content su-u-clearfix su-u-trim\" style=\"border-bottom-left-radius:1px;border-bottom-right-radius:1px\">A Complete Guide To The <a title=\"Difference Between Brushless Motor and Brushed Motor\" href=\"https:\/\/www.linquip.com\/blog\/the-difference-between-brushless-motor-and-brushed-motor\/\" target=\"_blank\" rel=\"noopener\">Difference Between Brushless Motor and Brushed Motor<\/a><\/div><\/div>\n<h2><span class=\"ez-toc-section\" id=\"What_Is_an_AC_Motor\"><\/span>What Is an AC Motor?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400\">The motor that converts the alternating current into mechanical power by using an electromagnetic induction phenomenon is called an AC motor. This motor is driven by an alternating current. Just like a DC motor, the AC motor also consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field.<\/span><\/p>\n<div class=\"su-box su-box-style-default\" id=\"\" style=\"border-color:#00021e;border-radius:3px;max-width:none\"><div class=\"su-box-title\" style=\"background-color:#263551;color:#89cabd;border-top-left-radius:1px;border-top-right-radius:1px\">Read More on Linquip<\/div><div class=\"su-box-content su-u-clearfix su-u-trim\" style=\"border-bottom-left-radius:1px;border-bottom-right-radius:1px\">A complete Guide to The <a title=\"Difference Between Stepper Motor and DC Motor\" href=\"https:\/\/www.linquip.com\/blog\/difference-between-stepper-motor-and-dc-motor\/\" target=\"_blank\" rel=\"noopener\">Difference Between Stepper Motor and DC Motor<\/a><\/div><\/div>\n<h2><span class=\"ez-toc-section\" id=\"The_Difference_Between_DC_Motor_and_AC_Motor\"><\/span>The Difference Between DC Motor and AC Motor<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400\">The most basic <\/span><span style=\"font-weight: 400\">difference between DC motor and AC motor<\/span><span style=\"font-weight: 400\"> is the power source.
