A new method to detect rotor cage fault of induction motor is presented, which monitors if the output power signal comprises a direct component and an alternating component or only a direct component.
通过判断电动机输出功率信号中是含有一个直流分量和一个余弦分量还是仅含有直流分量，判断鼠笼转子有无故障，提出了一种感应电机转子故障检测的新方法。
Reasonable thermal structure designs, comprehensive and reliable hardware protection measures, with a power soft-start function and functions of software self-diagnostics and fault output latch.
散热结构设计合理，硬件保护措施可靠完善，具有电源软启动功能，软件对故障进行自诊断以及输出闭锁等功能。
The power supply shall be protected when any output operation in circuit short condition. The power supply shall be Auto restart when the fault condition is removed.
在任何时候，任何输入条件下，当输出操作在短路情况下，电源供应器将进入保护模式，当故障消失后，电源要能自动恢复正常。
When the output voltage is over 40v the product is protected. When the fault is excluded or is start working again the power supply is working normally.
当输出电压超过40v时，产品进入保护状态，当故障排除或重新起机时，电源工作正常。
