1. A personal care system, comprising:
a personal care device drive unit; and
a plurality of functional units connectable to the personal care device drive unit, wherein the plurality of functional units are different types of personal care accessories, respectively, for performing different types of personal care of a user, wherein each functional unit of the plurality of functional units comprises a movable functional component configured for rotating motion or reciprocating motion, wherein one functional unit of the plurality of functional units is connectable to the personal care device drive unit at a time, and
wherein the personal care device drive unit comprises:
a main body;
a motor arranged in the main body;
a connection interface arranged on the main body and configured to releasably connect any functional unit of the plurality of functional units to the main body and to enable driving of the movable functional component of the connected functional unit by the motor via an output shaft;
a current sensor arranged in the main body for measuring an electric current of the motor caused by the motor driving the connected functional unit via the connection interface;
a vibration sensor arranged in the main body for measuring a vibration of the main body caused by the motor driving the connected functional unit via the connection interface; and
a controller arranged in the main body and configured to identify the connected functional unit from the measured electric current measured by the current sensor and the measured vibration measured by the vibration sensor, and to generate an output signal indicating the connected functional unit.
