Reluctance force LSR
Launched in 2016, the reluctance force LSR is particularly suitable for applications that require large format glass diffusers. The basis of this approach is a single thin steel structure that is brought into resonance by pulsing an actuating coil with current, which generates a strong reluctance force. Thanks to a high q-factor large amplitudes in the range of 800um are achieved at low power consumption even for heavy glass diffusers.
Advantages:
- Compact design with integrated actuator
- Works with different diffusor materials
- Driving electronics integrated on flex-cable
- Robust design for harsh environments
- Long operational lifetime
