Series motor<\/strong><\/p>\n<p>A series motor is a type of DC motor that has the field winding and the armature winding connected in series with the power source. This means that the current flowing through the field winding is the same as the current flowing through the armature winding. This results in a high starting torque, which makes series motors ideal for applications such as cranes and hoists.<\/p>\n<p>A shunt motor is a type of DC motor that has the field winding connected in parallel with the armature winding.

The series field winding is connected in series with the armature winding, and the shunt field winding is connected in parallel with the armature winding. This results in a motor with a high starting torque and a good speed regulation.<\/p>\n<p>A differentially compounded motor is a type of DC motor that has both a series field winding and a shunt field winding. The series field winding is connected in series with the armature winding, and the shunt field winding is connected in parallel with the armature winding.

This results in a motor with a low starting torque and a poor speed regulation.<\/p>\n<p>In conclusion, a series motor is generally preferred for cranes and hoists because it has a high starting torque.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[743],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Which D.C. motor is generally preferred for cranes and hoists?<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/exam.pscnotes.com\/mcq\/which-d-c-motor-is-generally-preferred-for-cranes-and-hoists\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Which D.C. motor is generally preferred for cranes and hoists?\" \/>\n<meta property=\"og:description\" content=\"Join Our Telegram Channel Subscribe on YouTube\" \/>\n<meta property=\"og:url\" content=\"https:\/\/exam.pscnotes.com\/mcq\/which-d-c-motor-is-generally-preferred-for-cranes-and-hoists\/\" \/>\n<meta property=\"og:site_name\" content=\"MCQ and Quiz for Exams\" \/>\n<meta property=\"article:published_time\" content=\"2024-04-15T22:38:10+00:00\" \/>\n<meta name=\"author\" content=\"rawan239\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"rawan239\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"2 minutes\" \/>\n<!-- \/ Yoast SEO Premium plugin. -->","yoast_head_json":{"title":"Which D.C. motor is generally preferred for cranes and hoists?","robots":{"index":"index","follow":"follow","max-snippet":"max-snippet:-1","max-image-preview":"max-image-preview:large","max-video-preview":"max-video-preview:-1"},"canonical":"https:\/\/exam.pscnotes.com\/mcq\/which-d-c-motor-is-generally-preferred-for-cranes-and-hoists\/","og_locale":"en_US","og_type":"article","og_title":"Which D.C. motor is generally preferred for cranes and hoists?","og_description":"Join Our Telegram Channel Subscribe on YouTube","og_url":"https:\/\/exam.pscnotes.com\/mcq\/which-d-c-motor-is-generally-preferred-for-cranes-and-hoists\/","og_site_name":"MCQ and Quiz for Exams","article_published_time":"2024-04-15T22:38:10+00:00","author":"rawan239","twitter_card":"summary_large_image","twitter_misc":{"Written by":"rawan239","Est. reading time":"2 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/exam.pscnotes.com\/mcq\/which-d-c-motor-is-generally-preferred-for-cranes-and-hoists\/","url":"https:\/\/exam.pscnotes.com\/mcq\/which-d-c-motor-is-generally-preferred-for-cranes-and-hoists\/","name":"Which D.C. motor is generally preferred for cranes and hoists?","isPartOf":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/#website"},"datePublished":"2024-04-15T22:38:10+00:00","dateModified":"2024-04-15T22:38:10+00:00","author":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/#\/schema\/person\/5807dafeb27d2ec82344d6cbd6c3d209"},"breadcrumb":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/which-d-c-motor-is-generally-preferred-for-cranes-and-hoists\/#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/exam.pscnotes.com\/mcq\/which-d-c-motor-is-generally-preferred-for-cranes-and-hoists\/"]}]},{"@type":"BreadcrumbList","@id":"https:\/\/exam.pscnotes.com\/mcq\/which-d-c-motor-is-generally-preferred-for-cranes-and-hoists\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/exam.pscnotes.com\/mcq\/"},{"@type":"ListItem","position":2,"name":"mcq","item":"https:\/\/exam.pscnotes.com\/mcq\/category\/mcq\/"},{"@type":"ListItem","position":3,"name":"Electrical engineering","item":"https:\/\/exam.pscnotes.com\/mcq\/category\/mcq\/electrical-engineering\/"},{"@type":"ListItem","position":4,"name":"D.c.
