Abstract:
The invention relates to an energy harvester for converting vibrational motion of a vibrating equipment into electrical energy. The energy harvester comprises a pendulum arranged to be pivotably attached to said vibrating equipment, a motion limiter arranged to limit a pivoting motion of said pendulum, and a generator connected to said pendulum and arranged to convert said pivoting motion into electrical energy. The vibrational motion has an operating frequency, and said pendulum has a natural frequency different from said operating frequency. The invention also relates to a device for monitoring the operation of a vibrating equipment.
