What are the important factors of crane motor quality

The quality of the crane motor is certainly an important factor. What choose commonly is the motor that passes quality attestation, although occasionally can have individual electric machine to appear quality problem, but stable electric machine quality enough can let you trust.

Another key factor is voltage, which is also a common factor affecting the lifting weight. Generally new residential areas are temporary electricity, will often appear voltage instability, will lead to the motor is not strong, lifting weight reduction. The design rated voltage of general hoisting motor is 220v plus or minus 5v. If the voltage fluctuates beyond this range, it will cause different degrees of heating of the motor, resulting in the reduction of motor power and lifting weight.

Other factors are also many, the main is the motor heat dissipation is not good, resulting in overheating of the motor, the motor will naturally be boring, generally to strengthen the heat dissipation, remove the housing of the main engine, increase the blower heat dissipation and other means.
