Any other usage is consider improper and prohibited. Layout This chapter describes the variants, layout and functionality of the BFK518 spring-applied brake. 3.2.1 Spring-applied brake BFK518 Fig. 1: Structure and layout of an INTORQ BFK518 spring-applied brake Rotor Counter friction surface (flange) Armature plate Coil Stator... -
Page 11: Function
Product description Function This brake is an electrically releasable spring-applied brake with a rotating brake disk (rotor) that is equipped on both sides with friction linings. In its de-energized state, the rotor is clamped with spring force applied by pressure springs between the armature plate and a counter friction surface. This corresponds to a fail-safe functionality. -
Page 12: Technical Specifications
Technical specifications Technical specifications Possible applications of the INTORQ spring-applied brake ¾ Degree of protection: – The brake is designed for operation under the operating conditions that apply to IP00 protection. Because of the numerous possibilities of using the brake, it is still necessary to check the function- ality of all mechanical components under the corresponding operating conditions. -

Page 15: Electromagnetic Compatibility
Technical specifications Electromagnetic compatibility Notice The user must ensure compliance with EMC Directive 2014/30/EC using appropriate controls and switching devices. Emissions Heat Since the brake converts kinetic energy and electrical energy into heat, the surface temperature varies considerably, depending on the operating conditions and possible heat dissipation. A surface temperature of 130 °C may be reached under unfavorable conditions. -
