中文
含义
测速传感器信号丢失,控制板无法获取电机转速反馈。
常见原因
测速传感器(霍尔元件/线圈)故障、传感器线束断裂或连接器接触不良、传感器与磁环间隙异常。
自助排查
- 检查测速传感器线束是否完好无破损。2. 重新插拔传感器连接器。3. 目视检查转子磁环是否完整。4. 如线束正常需更换测速传感器。
English
Meaning
Tachometer signal loss — the control board cannot receive motor RPM feedback.
Common Causes
Faulty Hall-effect or coil tachometer sensor, broken sensor wiring, loose connector, or improper air gap between sensor and rotor magnet ring.
Self-Check Steps
- Inspect tachometer wiring for damage. 2. Re-seat sensor connector. 3. Visually check rotor magnet ring for cracks or missing magnets. 4. Replace tachometer sensor if wiring is intact.
