(I) The temperature rise of the motor in overload operation increases or decreases in direct proportion to the total loss of the motor, and the copper loss of the harmonic water-cooled harmonic FHA-17C-50-E250-C is proportional to the square of the current except the iron loss is fixed. Therefore, the motor in overload operation increases the total loss, which is easy to cause the motor to heat up;

(2) Poor cooling large motor generally adopts air and water cooling harmonic water cooling harmonic FHA-17C-50-E250-C when cooled by air, the inlet air temperature is too high, which is adverse to motor cooling; High ambient air temperature and improper tuyere position also affect the cooling of the motor; On the other hand, the cooling effect will be reduced due to the insufficient air volume caused by the air filter blockage in the air duct, the airway in the fuselage is not smooth, and the air leakage in the pipeline. When the water cooling harmonic FHA-17C-50-E250-C is cooled by water, the water quantity is insufficient because the pipe is blocked, the pump is faulty, the water quantity in the pool is low, etc
