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 a 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.

5X00453G01 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.

5X00453G01 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.
