  • Page 52 Technical specifications 3.1.1 General information The spring-applied brake is designed for converting mechanical work and kinetic energy into heat energy. Due to the static braking torque, loads can be held at standstill. Emergency braking is possible at high speed of rotation. The wear increases as the switching energy increases (operating speeds 17).
  • Page 53 Technical specifications 3.1.3 Brake release When the brakes are applied, an air gap “s ” is present between the stator (1.1) and the armature plate (2). To release the brake, the coil of the stator (1.1) is energised with the DC voltage provided. The resulting mag- netic flux works against the spring force to draw the armature plate (2) to the stator (1.1).

  • Page 58 Technical specifications Emissions Electromagnetic compatibility NOTICE The user must ensure compliance with EMC Directive 2014/30/EU using appropriate controls and switching devices. If an INTORQ rectifier is used for the DC switching of the spring-applied brake: If the switching frequency exceeds five switching operations per minute, the use of a mains filter is required. If the spring-applied brake uses a rectifier from another manufacturer for the switching, it may become nec- essary to connect a spark suppressor in parallel with the AC voltage.

  • Page 80 Maintenance and repair Maintenance and repair Wear of spring-applied brakes INTORQ spring-applied brakes are wear-resistant and designed for long maintenance intervals. The friction lining and braking mechanism are subject to operational wear. For safe and trouble-free operation, the brake must be checked at regular intervals or replaced, if necessary NOTICE The air gap must not be re-adjusted after it has been correctly adjusted during the initial installation of the brake on the motor! This could result in a loss of braking torque.
  • Page 81 Maintenance and repair Inspections To ensure safe and trouble-free operations, the spring-applied brakes must be checked at regular intervals and, if necessary, replaced. Servicing will be easier at the plant if the brakes are made accessible. This must be considered when installing the drives in the plant. Primarily, the required maintenance intervals for industrial brakes result from their load during operation.
