![三木プーリの無励磁作動形ブレーキ BXR[LE]タイプ 製品画像（無励磁作動 保持用・低発塵仕様・電磁ブレーキ）](/media/cb_of_hld_0le_0l.jpg)
This is a non-excitation-type holding brake designed to be used in conjunction with a dedicated controller that regulates both the electrical energy required to overcome the spring force during the initial phase of brake release and the electrical energy needed to maintain the released state. This design achieves energy savings, low heat generation, and a compact profile.
