Electric gourds are used in industrial and mining enterprises, warehousing docks and other places. They have the characteristics of small size, light self -heavy, simple operation, and convenient use.The waterproof electrical gourd is required for corrosive places. Of course, electric gourd motors of different performances are also very different, but no matter which motor, the reasons for being easily destroyed are basically the same. The main reasons are: overload, short -circuit, defects, sweeping, etc. Factors 2: Small power and great factors: As the technology continues to improve the volume of the motor is getting smaller and smaller, the power is getting larger and larger, which leads to the smaller thermal capacity of the motor and weaker load capacity. Frequent work factors: Due to the improvement of automation levels, more frequent startup operations in the work, braking load, and motor protection devices are more stringent. Even so, motors are more likely to damage.
