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 sensor fitted with a shoe of the stator and configured to measure a presence or absence of eccentricity of the rotor by measuring a change in magnetic field generated between the rotor and the stator;
• a first sensing terminal formed integrally with a terminal assembly of the stator and configured to transfer sensing information of the eccentricity measurement sensor to the outside;
• a second sensing terminal having one surface that adjoins an axial distal end surface of the stator, the second sensing terminal being configured to transfer sensing information of the eccentricity measurement sensor to the first sensing terminal;
• and
• a connection substrate configured to electrically connect the first sensing terminal and the second sensing terminal.
