The correct answer is: B. armature input<\/strong><\/p>\n The rotor copper losses in a synchronous motor are met by the armature input. The armature is the part of the motor that rotates, and it is made up of a number of copper windings. When current flows through these windings, they create a magnetic field that interacts with the magnetic field of the stator, which causes the rotor to rotate. The amount of current that flows through the armature windings is determined by the motor’s load. When the motor is under a heavy load, more current flows through the windings, and the rotor copper losses increase.<\/p>\n The other options are incorrect because:<\/p>\n [amp_mcq option1=”d.c. source” option2=”armature input” option3=”motor input” option4=”supply lines” correct=”option2″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[965],"tags":[],"class_list":["post-45724","post","type-post","status-publish","format-standard","hentry","category-synchronous-motors","no-featured-image-padding"],"yoast_head":"\n\n
