Contrary to almost all wind turbines this is a vertical axis wind turbine with two blades standing upright. The appearance of the rotor mirrors the letter &#8220;H&#8221; telling why these machines are usually called &#8220;H-Rotors&#8221;.<\/p>\n<p>One hoped to achive major advantages\u00a0 to conventional horizontal axis wind turbines e.g. fewer components, less wear, a simpler design and easier maintenance.<\/p>\n<p>The Heidelberg-Motors got their ring generator placed either on top or at the bottom of the tower.<\/p>\n<figure id=\"attachment_1059\" aria-describedby=\"caption-attachment-1059\" style=\"width: 397px\" class=\"wp-caption alignnone\"><a href=\"http:\/\/deutsches-windkraftmuseum.de\/wp-content\/uploads\/HMW_300.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1059\" src=\"http:\/\/deutsches-windkraftmuseum.de\/wp-content\/uploads\/HMW_300.jpg\" alt=\"\" width=\"397\" height=\"264\" \/><\/a><figcaption id=\"caption-attachment-1059\" class=\"wp-caption-text\">Manager Jaeger and chairman Bosse behind the HM-300 model.
