EPILATOR AND METHOD FOR DRIVING EPILATOR

摘要

An electric razor (1) is provided with a linear actuator (10) having a stator (11) which includes an electromagnet (winding (11a)) and also having a moving element (12) which includes a permanent magnet (12a). The electric razor (1) is also provided with an amplitude control unit (40) and a control/output unit (50), which detect the amplitude and speed of the moving element (12) on the basis of an induced voltage occurring in the winding (11a) of the stator (11) as the moving element (12) reciprocates, compare the detected speed and a formerly detected speed, and, according to the difference representing the result of the comparison, change a method for controlling the moving element (12).
