Holding and coupling with the lowest energy requirement

As a general rule, electromagnetic brakes and clutches require a constant power supply to operate them. However, when it comes to bistable products, continuous power is not necessary. The operating principle is based on the precise interaction of the coil, permanent magnets and spring forces. In this case, the spring force and magnetic force of the permanent magnets are dimensioned so that the specified torque of the products is safely transmitted without any current. Even in the event of a power failure, the last condition applied will still be ensured. All it takes to change the switching state is a short current pulse. A further pulse opens or closes the product again, accordingly.

Particularly in mobile applications with ever-increasing demands with regard to energy efficiency, good environmental balance and safety, such as in electric vehicles, these products are used directly or in auxiliary systems because energy is only required to change the switching state. As a result, it is possible to achieve longer life cycles or range maximisation.

  • Zero energy consumption except for the switching pulse
  • No random opening or closing, even in the event of a power failure
  • Maintenance-free plug and play units
  • IATF 16949 certification
