 1. The use of high-efficiency energy-saving motors is effective for long-term constant load operation; the use of energy-saving motors in the production process is to improve the operational efficiency of the motor itself, or to enhance the energy conversion rate.

2. Adopt reactive power compensation measures; utilize motors and energy storage capacitor devices for reactive power compensation. The active and reactive power required for motor operation is provided by the power grid. Therefore, in lines carrying both active and reactive power, the lines constitute a relatively large loss. It is described that the terminal reactive power compensated by capacitors can be provided independently relative to inductive loads, and the reactive power of transmission lines can be reduced or not reduced, rather than reducing the current of the load circuit. This reduces line loss, also reduces the reactive power of transformers, and improves the utilization rate of power transmission.

3. It is preferable for fans, pump motors, and variable frequency systems to operate under intermittent loads. Saving energy by adjusting motor speed refers to frequency energy. Frequency converters are primarily used in situations where loads vary, and their energy-saving effect is very significant, typically in constant pressure water supply systems. The principle of energy is simple: it involves changing the frequency to alter the power output. In situations where the load is stable, that is, without a speed regulator, using a frequency converter will reduce overall efficiency but will waste power. Among them, average frequency control can save 30% of energy, with significant energy-saving effects and a wide range of applications, making it one of the main methods of electric energy.
