How to realize energy saving and consumption reduction of high-efficiency and energy-saving motors

Previously, the editor has introduced in detail the energy-saving measures of high-efficiency energy-saving motors. From this, we can understand that the energy-saving of this motor is a complex and systematic process because it involves its life cycle. In the process of energy saving, we must take correct energy saving measures based on life cycle influencing factors. So how to achieve energy saving and consumption reduction of high-efficiency and energy-saving motors? I believe this issue is something that many companies have been paying attention to. Let’s analyze it in detail below!

However, in the production operations of many enterprises, how to ly realize energy saving and consumption reduction of high-efficiency energy-saving motors, the power source of mechanical equipment, is believed to be one of the important ways for many enterprises to reduce costs and improve efficiency. We can mainly start from the following Let’s start with several aspects:

1. Use high-efficiency, energy-saving motors

For high-efficiency and energy-saving motors with an annual operation of more than 3000 hours, YX3 high-efficiency motors and CGX series ultra-high-efficiency motors should be selected. The CGX series of ultra-efficient motors is a new type of energy-saving motor product developed by our company based on the needs of some high-end users and through the continuous efforts of scientific and technical personnel. It uses energy-saving fans, high-performance grease, and bearings with low damping coefficients to reduce ventilation losses and friction losses; it uses heat-resistant, thin insulation materials to increase winding turns or expand conductor cross-sections. The selection of high-quality and reliable enameled wire improves the conductivity of the wire and effectively reduces the copper loss of the motor; thus further improving the operating efficiency of the high-efficiency and energy-saving motor.

2. Take reasonable energy-saving measures during operation

① Reasonably select the capacity of the motor to avoid the phenomenon of "big horse and small cart" and increase the load rate. When the load rate reaches above 70%, its operating efficiency will reach the efficiency.

② When a high-power delta connection motor is started or under light load, it can be changed to a star connection to reduce the winding phase voltage, reduce iron loss, improve the power factor, and reduce the stator current. It has useful Better energy saving effect.

③Choose a control method with good energy-saving effect. For situations where the load is constantly changing, we can use a frequency converter to control the motor. According to the output of the motor at different times, we can reasonably distribute the electric energy.

④ Small motors that run periodically should be equipped with automatic parking devices when no-load to reduce no-load losses. This can not only achieve the purpose of saving electricity, but also improve the power factor of the power supply line.

3. Correctly maintain high-efficiency and energy-saving motors

When performing repair work on motors, we can use magnetic tank mud to rebuild old motors. Magnetic tank mud has magnetic permeability. When the magnetic induction intensity is 0.8T, the relative magnetic permeability is 2 to 4.5. It is a plastic material that can be solidified at the slot mouth. It has good fastening properties and can be used in medium and Small motor, it can increase efficiency by 1.25% and reduce temperature rise by 13K on average.

Under increasingly severe environmental pressure, the rational use of high-efficiency and energy-saving motors can effectively achieve energy conservation and emission reduction, and also protect the environment. For enterprises, it can increase revenue and reduce expenditure; for the country, it can also solve energy shortages and reduce pressure on the power grid. Taken together, they all have good practical significance.
