Eccentricity measurement system

An eccentricity measurement system, which is applied to a motor system comprising a stator and a rotor and measures eccentricity of the rotor, the eccentricity measurement system comprising:

• an eccentricity measurement part measuring presence or absence of the eccentricity of the rotor by measuring a change in magnetic field generated between the rotor and the stator, the eccentricity measurement part comprising one or more eccentricity measurement sensors;
• and
• a sensing housing including:
• one surface, in which the eccentricity measurement part is embedded;
• and
• a center hole formed through a center of the sensing housing, wherein a rotary shaft of the rotor is fitted into the center hole,
• wherein the eccentricity measurement part is coupled to one front surface of the sensing housing and includes one sensing board disposed on one surface of the eccentricity measurement part so that the one or more eccentricity measurement sensors are embedded in the sensing board, and
• wherein the one or more eccentricity measurement sensors include a sensing terminal extending in an axial direction and electrically connected to the sensing board.
