According toMotorAccording to the staff's introduction, the motor system usually consists of a power system consisting of three parts: a motor, a control unit, and a mechanical transmission deceleration structure. A simple energy-saving motor system only includes the motor and its control unit.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.Explosion-proof motorsA type of motor that can be used in flammable and explosive plants, and does not generate sparks during operation.Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.So how can the engine achieve better energy saving?Let's take a look:
(2) In terms of a motor company that can achieve energy conservation in China, the state has issued mandatory technical standards for small and medium-sized three-phase asynchronous motors with a wide range of applications. Those that meet their level 90.5 energy efficiency indicators are for the efficient development of energy-saving motors ( Referred to as high-efficiency motor).The average working efficiency of high-efficiency and energy-saving motors is XNUMX%, which has reached some European EFFXNUMX standards, which is comparable to the level of high-efficiency motors in developed countries.
(60) According to the characteristics of the efficiency curve of the motor, energy saving of the enterprise can be realized.In actual development applications, the load efficiency of most motors is often below 60%. Under normal circumstances, the load efficiency is between 80% and XNUMX% and the learning efficiency is relatively high.The phenomenon of large horse-drawn carts is a common problem. If a long-term low-load operation is in progress, it will easily cause damage to the motor.Therefore, the electromechanical technicians of our country provide suggestions that most motors should be adjusted according to the load change. The installation of speed control units for existing motor products is to turn traditional motors into energy-saving motors and gradually become a very economical solution in China. .
The motor-saving system usually adopts the new motor deceleration part to optimize the mechanical transmission device of the system. By reducing the loss of mechanical energy, energy saving of the entire motor drive system is achieved.We hope that through the above methods, we can better realize electric energy and create a more environmentally friendly and energy-saving market environment.
