As a result, the door operates more smoothly, with less vibration and lower noise levels, while maintaining stable performance even under continuous high-frequency operation.<\/p>\n<figure id=\"attachment_21013\" aria-describedby=\"caption-attachment-21013\" style=\"width: 1200px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-21013 size-full\" title=\"\u0110\u1ed9ng c\u01a1 DC kh\u00f4ng ch\u1ed5i than trong b\u1ed9 truy\u1ec1n \u0111\u1ed9ng c\u1eeda t\u1ef1 \u0111\u1ed9ng\" src=\"https:\/\/sonha.com\/wp-content\/uploads\/2026\/07\/hanh-trinh-cai-tien-cong-nghe-cua-cua-tu-dong-nabco-7.jpg\" alt=\"\u0110\u1ed9ng c\u01a1 DC kh\u00f4ng ch\u1ed5i than trong b\u1ed9 truy\u1ec1n \u0111\u1ed9ng c\u1eeda t\u1ef1 \u0111\u1ed9ng\" width=\"1200\" height=\"674\" srcset=\"https:\/\/sonha.com\/wp-content\/uploads\/2026\/07\/hanh-trinh-cai-tien-cong-nghe-cua-cua-tu-dong-nabco-7.jpg 1200w, https:\/\/sonha.com\/wp-content\/uploads\/2026\/07\/hanh-trinh-cai-tien-cong-nghe-cua-cua-tu-dong-nabco-7-300x169.jpg 300w, https:\/\/sonha.com\/wp-content\/uploads\/2026\/07\/hanh-trinh-cai-tien-cong-nghe-cua-cua-tu-dong-nabco-7-1024x575.jpg 1024w, https:\/\/sonha.com\/wp-content\/uploads\/2026\/07\/hanh-trinh-cai-tien-cong-nghe-cua-cua-tu-dong-nabco-7-768x431.jpg 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption id=\"caption-attachment-21013\" class=\"wp-caption-text\"><em>Brushless DC motor integrated into an automatic door operator<\/em><\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"Why_are_brushless_DC_motors_used_in_premium_automatic_doors\"><\/span>Why are brushless DC motors used in premium automatic doors?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The <a href=\"https:\/\/sonha.com\/en\/what-is-an-automatic-door-motor\/\">motor<\/a> is one of the most critical components determining the durability, smoothness, and overall performance of an automatic door system.

By eliminating carbon brushes and relying entirely on electronic control, BLDC motors enable automatic doors to operate more smoothly, more reliably, and more efficiently while significantly reducing maintenance requirements. This is one of the primary reasons why leading Japanese automatic door manufacturers such as NABCO have adopted this technology across their automatic sliding doors, automatic swing doors, and automatic hospital doors, meeting the increasingly demanding requirements of modern buildings.<\/p>\n<p>If you are looking for the most suitable NABCO automatic door solution for your project, contact Sonha Auto today.
