ABSTRACT:
An electric shaver is provided with a motor to drive a cutter, a motor current sensing circuit, and a computation circuit which processes an output from the current sensing circuit. The computation circuit computes beard thickness, and a set range of motor rotational speed regulation according to beard thickness to lower rotational speeds for thin beards and to higher rotational speeds for thick beards, and thereby rotates the motor at optimum speeds according to beard thickness.
