Abstract

A test system for performance test of self-bonding iron core rotor, comprising a protective cover, the protective cover comprises a first cover body and a second cover body, the second cover body is detachably assembled on the first cover body, the first cover body is provided with a first receiving cavity, the first cover body is provided with a pair of first installation grooves and a first recess, the second cover body is provided with a second receiving cavity, the second cover body is provided with a pair of second installation grooves and a second recess, the second cover body is assembled on the first cover body, the first receiving cavity and the second receiving cavity are communicated for receiving a rotating shaft, the first installation groove and the second installation groove are correspondingly abutted to form an installation groove, a supporting bearing is arranged in the installation groove, the supporting bearing is sleeved on the rotating shaft, the first recess and the second recess are abutted to form a through hole through which a power end of the rotating shaft penetrates, the power end of the rotating shaft is connected with a driving motor, and the rotating shaft is used for sleeving a self-bonding iron core rotor to be tested. Through the test system, the use environment of the vehicle driving motor can be simulated, and the performance of the self-bonding iron core rotor can be tested.
