Dynamic balance inspection system and method thereof

A dynamic balance inspection system for performing dynamic balance inspection on a dynamic balancer with respect to a rotor of a motor, wherein the rotor comprises a positioning structure and a plurality of first counterweight portions located on a first side of the rotor, and the dynamic balance inspection system comprises:

• a first image-capturing unit disposed on the first side of the rotor and movable along an axial direction to capture a first image of a positioning structure located on a first terminal surface and a second image of the first counterweight portions located on a second terminal surface, wherein the first terminal surface and the second terminal surface are perpendicular to the axial direction and are spaced from each other in the axial direction;
• an offset angle calculation unit electrically connected to the first image-capturing unit to obtain a first orientation corresponding to the positioning structure according to the first image, obtain a second orientation corresponding to a first designated counterweight portion of the first counterweight portions according to the second image, and obtain a first angular difference between the first orientation and the second orientation;
• a dynamic balance test processing unit electrically connected to the dynamic balancer to receive a first compensation angle of the first side of the rotor and a first compensation mass corresponding to the first compensation angle from the dynamic balancer, wherein the first compensation angle is generated by using the positioning structure as a datum point of a dynamic balance polar coordinate system;
• and
• a compensation calculation unit electrically connected to the offset angle calculation unit and the dynamic balance test processing unit to generate at least one first actual compensation position and at least one first actual compensation mass corresponding to the at least one first actual compensation position according to the first angular difference, the first compensation angle and the first compensation mass.
