Suppressing Electromagnetic Interference TRIZ Cases
- Bypass Capacitor for Reducing Bearing Voltages in Insulated Electrical Machines
Connecting a bypass capacitor between the rotor and stator equalizes potentials, reducing harmful bearing voltages that damage insulated bearings.
- Alternator Brush Holder RF Immunity via Segmented Filter Circuit
A regulator brush holder integrates a separate filter circuit on an insulating substrate to attenuate radiofrequency interference signals.
- Brush Assembly EMI Suppression Circuit Board for Power Tools
A circuit board mounts X and Y capacitors on the brush assembly to ground interference, reducing emissions without increasing mounting complexity.
