How to judge the advantages and disadvantages of energy-saving and high-efficiency motors
Any product has its performance advantages and disadvantages, and similar products have their comparable performance tendencies and advancements. For energy-saving and high-efficiency motors, the basic requirements of the motor are rated speed, rated voltage, installation size, rated power, etc., and the vibration, power factor, efficiency, noise index, etc. of similar motors based on the above characteristics are compared with a motor. important indicators.
Motor variables - the same functions are used, and the power factor is one of the indicators that can be directly compared and tested. A relatively high power factor is one of the characteristics of the energy-saving level of energy-saving and high-efficiency motor products. The power factor reflects the ability of the motor to absorb electrical energy from the grid. Under the same power factor, high efficiency is the comparison standard for energy-saving and high-efficiency motors to convert electrical energy into mechanical energy.
Motor variables - under the premise that the efficiency level and power factor are similar, the temperature rise level, noise, and vibration of energy-saving and high-efficiency motors have different effects on the environment, body, and loading equipment. Here, it also involves supporting and manufacturing costs.
Therefore, to evaluate whether the performance level of the energy-saving and high-efficiency motor is superior, the corresponding reference objects should be selected, and qualitative and quantitative comparative analysis should be carried out for the same operating conditions. To evaluate the pros and cons of this type of performance of the motor, the corresponding indicators should be evaluated under the conditions of starting, no-load, load and overload operation of the motor through professional testing in accordance with the corresponding standard requirements.
