This series of motors complies with the industry standard GB755-2000 Rating and Performance of Rotating Electrical Machines and JB\/T7565.1-2004 *Technical Specifications for YB2 Series Flameproof Three-Phase Induction Motors (Frame Sizes H63\u2013355)*. Their explosion-proof performance meets the requirements of GB3836.1-2000 Electrical Apparatus for Explosive Gas Atmospheres \u2013 Part 1: General Requirements and GB3836.2-2000 Electrical Apparatus for Explosive Gas Atmospheres \u2013 Part 2: Flameproof Enclosure \"d\". They are manufactured as flameproof types ExdI, ExdIIAT4, and ExdIIBT4, suitable for hazardous locations in underground coal mines (excluding coal face excavation areas) and factory environments with explosive gas atmospheres of Classes IIA and IIB, temperature groups T1\u2013T4.<\/p>\n
The enclosure protection class of this series is IP54 or IP55, with a cooling method of IC416.
\nThis series can also be produced in variants for tropical damp, tropical dry, outdoor, outdoor with moderate corrosion resistance, and outdoor tropical damp conditions.<\/p>\n
Operating Conditions:<\/strong> The motor is equipped with a separate axial fan for forced ventilation, ensuring effective cooling during operation at varying speeds.<\/p>","protected":false},"excerpt":{"rendered":" \u672c\u7cfb\u5217\u7535\u52a8\u673a\u7b26\u5408GB755-2000\u300a\u65cb\u8f6c\u7535\u673a\u5b9a\u989d\u548c\u6027\u80fd\u300b\u884c\u4e1a\u6807\u51c6JB\/T7565.1-2004\u300aYB2\u7cfb\u5217\u9694…<\/p>","protected":false},"featured_media":1126,"template":"","meta":{"_kad_post_transparent":"default","_kad_post_title":"","_kad_post_layout":"default","_kad_post_sidebar_id":"","_kad_post_content_style":"default","_kad_post_vertical_padding":"default","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false},"product_brand":[],"product_cat":[22],"product_tag":[],"class_list":{"0":"post-1125","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-ex-proof-low-voltage-motors","8":"first","9":"instock","10":"taxable","11":"shipping-taxable","12":"product-type-simple","13":"entry","14":"content-bg","15":"loop-entry"},"_links":{"self":[{"href":"https:\/\/www.shfbdj.com\/en\/wp-json\/wp\/v2\/product\/1125","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.shfbdj.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.shfbdj.com\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.shfbdj.com\/en\/wp-json\/wp\/v2\/media\/1126"}],"wp:attachment":[{"href":"https:\/\/www.shfbdj.com\/en\/wp-json\/wp\/v2\/media?parent=1125"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.shfbdj.com\/en\/wp-json\/wp\/v2\/product_brand?post=1125"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.shfbdj.com\/en\/wp-json\/wp\/v2\/product_cat?post=1125"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.shfbdj.com\/en\/wp-json\/wp\/v2\/product_tag?post=1125"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
