1. The use of high-efficiency energy-saving motors, which are designed to maintain high efficiency under long-term constant load, is effective; these motors aim to improve the operational efficiency of the motor itself or enhance the energy conversion rate during consumption.  
2. Adopt reactive power compensation measures; install a capacitor on the motor for reactive power compensation. The motor provides the required reactive power to operate the grille, thus, when carrying both active and reactive power lines, which constitute relatively large losses, the capacitors used as terminals generate reactive power compensation that can be autonomously provided relative to the electrical load. The reactive power lines can be reduced or eliminated, and conversely, when the load circuit current decreases, it reduces line losses and also reduces the transformer's reactive power to improve the transmission of the application.
3. For fan and pump motors, inverter systems with intermittent loads are better; adjusting the motor speed to conserve power refers to frequency energy; inverters are mainly used in situations where the load varies, and the energy-saving effect is very significant, typically in constant pressure water supply systems. The principle of energy is simply to change the frequency, thereby changing the output power. For example, if the power requirement is only 5kW, but the motor can output 10kW of power if not speed-controlled, this is a waste of 5kW. For places with stable loads, that is, without load fluctuations, the use of drives will reduce overall efficiency. Among them, uniform frequency control can save 30% of energy, and the application range is widespread, making it a major approach in electric energy utilization.
