There are an armature and one or many permanent magnets placed around the armature. This type cannot supply much power due to the design of the generator and does not employ it in industry applications. Permanent magnet DC generators usually are used in small applications, the same as dynamos in motorcycles.<\/p>\n<p>Figure 2 illustrates the basic form of the permanent magnet DC generators, and as we know, voltage is created when the wire cuts the field and the amount of it is dependent on the wire loops and the rate of rotation in the field. Also, the amount of the voltage is the function of the angle between the magnetic flux and the moving surface. As each loop rotates, the voltage varies from 0 to the maximum amount of itself as the function of the angle and makes an absolute amount of sinusoidal voltage. Increasing the number of loops at different angles makes the voltage to be constant at its maximum value.<\/p>\n<figure id=\"attachment_4894\" aria-describedby=\"caption-attachment-4894\" style=\"width: 1057px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-4894\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Capture.png\" alt=\"types of DC generators\" width=\"1057\" height=\"504\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Capture.png 1057w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Capture-300x143.png 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Capture-1024x488.png 1024w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Capture-768x366.png 768w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Capture-696x332.png 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Capture-881x420.png 881w\" sizes=\"(max-width: 1057px) 100vw, 1057px\" \/><figcaption id=\"caption-attachment-4894\" class=\"wp-caption-text\">Figure2.
