Sensing Method for Resonant Actuators (– Candidate in progress)
Engineering Innovation Mechatronics R&D Electronics
Problem description The resonant magnetic actuator is frequently used in power toothbrushes. This actuator offers several advantages over a drivetrain that uses a permanent-magnet motor with an eccentric cam. It is significantly easier to achieve a quiet, high-frequency driver with a longer lifespan. Furthermore, the resonant drive can be considered a direct-drive system, which…
