Description
Technical field [0001] The present invention involves the production equipment field of permanent magnet electrical motor (rotor or stator), especially the online automatic overall magnetic expansion detection method and device that involves magnetic facilities. Background technique [0002] In the past, the production test of permanent magnet motor was mostly inspected the motor performance after the whole machine was assembled. Once it was not found, it could only be scrapped.For high -power permanent magnet motors (such as greater than 10kW), once the whole machine is found to be bad, the cost loss causes a lot.In addition, with the promotion of electric vehicles, the corresponding high -power permanent magnet motor application is becoming more and more widespread, especially the main driver motor application, which has higher requirements for motor performance and more detection items.Detection items and records.Among them, rotor (or stator) with permanent magnets has a magne...
