Any product has its suitability for performance, and similar products have its performance tendency and comparable advanced nature. For motor products, the installation size, rated voltage, rated power, rated speed, etc. of the motor are the basic universal requirements, and based on these functional characteristics, the efficiency, power factor, vibration and noise indicators of similar motors are the basic requirements for motors. Important indicators for product quantitative comparison.
For motors with the same function, the power factor is one of the indicators that can be directly tested and compared. The power factor reflects the ability of the motor to absorb electric energy from the grid. A relatively high power factor is one of the signs of the energy-saving level of the motor product.
Under the condition of the same power factor, relatively high efficiency is a sign of the advanced nature of the motor to convert the absorbed electric energy into mechanical energy.
On the premise that the power factor and efficiency level of the motor are equivalent, the vibration, noise and temperature rise of the motor will have varying degrees of impact on the use environment, the motor body, and the driven equipment. Of course, it will also involve the manufacturing cost and Use matching costs.
Therefore, to evaluate whether the performance level of the motor is superior, the corresponding reference object should be selected, and qualitative and quantitative comparative analysis should be carried out for the same operating conditions. To evaluate the performance of this type of motor, it should be in accordance with the corresponding standard requirements, after professional testing, to evaluate the corresponding indicators under the starting, no-load, load and overload operating conditions of the motor. Objectively speaking, the no-load characteristics are good, but the load characteristics of the motor are not necessarily good .
In addition, for non-professional motor users, the power consumption under the same workload conditions and the output results under the same power consumption conditions can be compared and analyzed.
GB/T 1032 is the normative standard for motor product testing. For those who are not familiar with motor performance testing, they can start from understanding the standard, and choose a standardized professional test structure for comparative testing, so as to evaluate the performance of the motor objectively.
