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.
