BYD CPD30 지게차 AC 구동 모터 고장 지지 부품 분석

BYD CPD30 지게차 AC 구동 모터 고장 지지 부품 분석(그림1)

BYD CPD30 포크리프트의 AC 드라이브 모터는 장비의 출력을 보장하는 핵심 구성 요소입니다. 장기간의 고강도 작동이나 부적절한 유지보수는 쉽게 다양한 고장으로 이어질 수 있습니다. 해당 부속품을 정확하게 식별하는 것이 장비 성능의 효율적인 유지 보수 및 복구의 핵심입니다.

스테이터 권선은 모터의 핵심 전도성 구성 요소입니다. 절연층이 손상되거나 권선이 단락되거나 열리면 모터가 시동이 어렵거나 전원이 부족하거나 작동하지 않습니다. 이러한 종류의 고장은 대부분 장기간의 고온 작동, 전해질 부식 또는 이물질 침입으로 인해 발생합니다. 교체 시 새 권선의 사양이 원래 부품과 일치하는지 확인해야 합니다. 설치 후에는 2차 고장을 방지하기 위해 절연 성능을 테스트해야 합니다.

로터 어셈블리는 전자기 변환을 달성하기 위한 모터의 핵심 부분입니다. 로터에 자기극 탈자기화, 권선 개방 회로 또는 기계적 변형이 있는 경우 모터의 비정상적인 소음 및 불안정한 속도와 같은 문제가 발생합니다. 조사 중에 로터의 자기장 강도를 감지하고 로터의 외관 변형을 관찰하여 결함을 확인할 수 있습니다. 로터를 교체할 때 스테이터와의 일치 갭에 주의하여 전자기 변환 효율이 표준에 부합하는지 확인하십시오.

베어링 부품에는 로터의 지지 및 회전 기능이 있습니다. 장기간 고속 작동 또는 불충분한 윤활은 베어링이 마모되고 고착되기 쉬우며, 이는 모터가 작동 중일 때 명백한 비정상적인 소음과 비정상적인 온도 상승으로 나타납니다. 베어링 교체 시 적절한 유형의 제품을 선택하고 설치 전에 청소 및 윤활하여 부적절한 설치로 인한 마모가 악화되지 않도록 해야 합니다.

인코더는 모터의 속도 및 위치 신호를 모니터링하는 데 사용됩니다. 인코더가 신호를 잃고 감지 정확도가 떨어지면 포크리프트의 속도가 불안정해지고 스티어링 제어가 실패합니다. 조사 중에 인코더의 출력 신호의 안정성을 감지하여 고장을 판단할 수 있습니다. 교체 시 신호 간섭을 방지하기 위해 인코더의 설치 위치가 정확한지 확인해야 합니다.

드라이브 컨트롤러는 AC 드라이브 모터의 제어 코어입니다. 컨트롤러에 회로 고장이나 프로그램 오류가 있으면 제너레이터가 시동되지 않고 출력이 비정상적입니다. 이러한 결함은 전문 테스트 장비에서 확인해야 합니다. 회로가 켜지거나 꺼지고 프로그램이 실행 중입니다. 컨트롤러를 교체할 때 모터와 차량 시스템에 적합한지 확인하기 위해 매개 변수를 일치시켜야 합니다.

일상적인 작동 및 유지 보수에서는 AC 구동 모터의 다양한 부속품을 정기적으로 점검 및 유지 관리하고 부품 표면의 먼지와 오일을 제때 청소하고 윤활 및 절연 보호를 잘 수행하여 선원의 고장 가능성을 줄여야 합니다. 고장이 발생했을 때는 고장 현상과 함께 해당 부품을 정확하게 찾아 교체 및 시운전 표준 프로세스를 따라 지게차의 안정적인 작동을 보장해야 합니다.
