For many years, miniaturisation has been a driving force in technical progress. Intimately connected with miniaturisation is the desire for little mass and low energy consumption. This trend is now also affecting braking technology: The diameter of the currently smallest permanent magnet brake in the world is less than the diameter of a 1-Cent coin. Therefore the brake fits perfectly with small electric motors.
The position of the motor shaft, e.g. the final position, can now also be hold when the brake is not energised. The results are conservation of energy and less waste heat. Such applications mostly also benefit from the limited weight of the small brake. The spectrum reaches from robotics and medical engineering to aerospace engineering or mobile applications in other sectors.
