SPDSM04 One of the important means to reduce carbon emission is to save energy, we can look at a set of data, in 2023, China’s industrial electricity accounted for 65.8% of the total electricity consumption of society, of which 75% came from industrial motors, that is to say, the motor is the largest single type of power consumption transmission equipment.
We have done a simple calculation, if the energy efficiency of these motors is increased by 3%, then it will save 182.1 billion KWH of electricity per year, which is equivalent to the annual power generation of the Three Gorges Dam. Therefore, the popularity of high-efficiency motors must be the trend of the future industry.
When it comes to high-efficiency motors, we have to mention another topic, that is, motor volume. If the existing technology is used to improve the energy efficiency of the motor, the volume of the motor will be more or less increased, so that many scenarios using the motor will have problems, such as the overall structure of the equipment plant needs to be adjusted, the load bearing of the motor installation needs to be redesigned, the transformation of the end user is affected by the structural changes of the original equipment, and ultimately directly affect the return on investment cycle.
There is still a lot of room for innovation in the transmission chain
In addition, we also found a problem, that is, the reasonable choice of motor and transmission structure. Motor technology has developed for nearly 200 years, and has also evolved many technical routes, but the development of the transmission structure with the motor is actually relatively rough, which also means that with the progress of motoSPDSM04 r technology, the innovation of the entire transmission chain has relatively large space for mining.
A few years ago, our Huichuan motor in the textile industry, for example, the customer’s original scheme is asynchronous machine belt connection, we use frameless permanent magnet motor to achieve direct drive, directly remove the belt efficiency loss, energy efficiency increased by 25%, to achieve maintenance-free, installation time reduced from two hours to 10 minutes, now the scheme has been fully promoted in the weaving industry. The proportion of high-efficiency motors in the industry is also increasing year by year.
Create the ultimate system benefits
Cross-border technology revolutionizes transmission
The content of the above is mainly two conclusions, one is that the popularity of high-efficiency motors must be the trend of future industrial development, and the other is that with the development of motor technology, there is still a lot of room for innovation on the transmission chain.
Based on the above conclusions led to our protagonist today, MV33 series Vplus-Pin flat wire industrial motor. This is aSPDSM04 cross-border use of flat wire technology motor, and is the first Huichuan flat wire hairpin technology applied to low-voltage industry permanent magnet synchronous motor.
The range of our release is mainly four speeds: 750rpm\1000rpm\1500rpm\3000rpm.
Among them, 750rpm power 18.5~90kW, 1000rpm power range 30~132kW, 1500rpm power range 37~200kW, 3000rpm power range 55~315kW, 180~250 four stands. Full IE5 energy efficiency.
What are the features of this product?
The smallest IE5 energy efficient industrial low pressure air cooled motor
First, it is the smallest IE5 energy efficient low-voltage industrial motor available today. Let’s make a comparison, to the current market circulation of the most IE3 energy efficient asynchronous motor for example, if the asynchronous machine to achieve IE5 then the volume will increase by 10% to 15%. If the permanent magnet motor design is used, the volume can be flat or reduced by 10%, but the flat line design of the MV33 is 25% to 40% less than the IE3 energy efficient asynchronous machine volume!
What are the benefits of volume reduction? To name a few.
First scene. A typical application scenario of industrial motors is to connect the gearbox through the coupling, the motor installation position is usually in the tail of the equipment, if the traditional IE3 asynchronous motor is replaced with MV33, to the commonly used 160kW, 1500 RPM motor as an example, the length of the entire equipment will be reduced by 385mm, significantly shorter. Can it be shorter on this basis? It’s okay. Since the flat wire motor in addition to the axial size is smaller, the outer diameter size is also smaller, you can turn the motor direction from the reverse installation, so the length of the entire equipment is shortened by 1700mm compared with the original structure, the original motor installation part is eliminated, the installation is flexible and convenient, and the space utilization of the end user is also greatly improved, these savings are real value to customers.
Look at another scene. The motor is usually connected to the load through the pulley, as can be seen from the figure, because the motor is too large, there is no way to achieve direct connection. However, if the MV33 motor is used, the motor can be placed on top and connected directly to the load through a coupling, eliminating the need for belt drive. By calculation, the high-efficiency motor itself can bring 1.7%~3.1% energy efficiency improvement, cancellation of belt drive energy efficiency will also increase 3%~8%, integrated, MV33 motor overall efficiency of 4.7%~11.1%. More than that, if the load end structure allows, the frameless structure can be used to further eliminate the coupling, the motor fixed rotor is directly installed on the load end, eliminating the motor bearing, and the overall transmission structure is further optimized.
Is it possible to use this scheme for all belt connections? Not really. According to the transmission structure of the actual equipment, combined with the performance of the motor itself through professional analysis to choose the most suitable transmission structure. Huichuan’s professional electrical engineering team is researching the innovation of transmission structure every day, and the small size of our flat wire motor provides more possibilities for our engineering team in transmission innovation.
Full range of IE5, can expand IE6
High performance zone double “90”
Let’s look at another feature of the MV33 series motor, high energy efficiency.
MV33 is a full system of high energy efficiency design, to meet IE5 and permanent magnet motor national standard level I energy efficiency, because IE5 and permanent magnet national standard level I energy efficiency on some power motor efficiency values are different, MV33 motor in the design of the two standards under the same specification of the highest energy efficiency value. In addition, the MV33 supports the expansion of IE6 energy efficiency, which reduces the loss of IE6 motors by 20% compared to IE5 motors.
It is worth mentioning that the energy efficiency level of the motor is nominal according to the efficiency value of the rated point of operation of the motor, and the high efficiency area of the general motor is near the rated point. However, when the customer is in actual use, most of the motor conditions are not long-term operation at the rated point, which means that many motors are in use, the actual efficiency is lower than the nominal value. For this scenario, we put forward the concept of double “90”, MV33 motor can achieve efficiency above 90% in 90% of the work zone. As a practical case, in a certain variable speed constant torque application scenario, MV33 compared with the ordinary round line design of IE5 permanent magnet motor, the overall energy saving is about 2%, and after conversion, it can save 3~6 thousand yuan per year. In the same scenario, the energy efficiency gains of MV33 will be greater than those of IE3 asynchronous machines.
