What kind of revolutionary wave will be triggered if hair-pin winding technology is introduced into the field of low voltage industrial permanent magnet motors?

Is hair-pin winding technology only applicable in the new energy industry?

When hair-pin winding technology is combined with permanent magnet direct drive technology, what kind of new sparks of innovation will be ignited?

Do you also have many question marks·········
 

In 2014, JASUNG bravely proposed a research and development plan and successfully developed the first industrial permanent magnet motor using flat wire winding technology.

Remarkably, this motor is still running smoothly at Panjiang Coal Power Group to this day, without any faults, maintaining its performance consistently over the past decade. In the same year, more of such motors have also excelled in various industries such as power and metallurgy.

 

As fervent advocates and practitioners of hair-pin winding technology in industrial permanent magnet motors, we can't help but ask: What unparalleled advantages does the application of hair-pin winding technology bring to industrial permanent magnet motors? Let's unravel this mystery together.

 

Enhanced Efficiency: Increased slot fill factor, reduced losses

ndustrial motors utilizing hair-pin widing technology can achieve a 20% to 30% increase in slot fill factor. This decrease in winding resistance effectively reduces copper losses, leading to a significant improvement in motor efficiency. This transformation not only elevates motor efficiency significantly but also sets a new benchmark for energy-saving and emission reduction in industrial production.

 

Compact Size, High Energy: Doubled power density

In the same volume, hair-pin winding motors can accommodate more stator windings. This innovative design allows for higher power and torque output of the motor under the same losses. Despite its small size, it holds remarkable energy, bringing forth more possibilities for industrial applications.

 

Resilience in Extreme Environments: Enhanced stability

Compared to traditional round wire motors, flat wire motors have a more regular shape, closer contact with the stator core teeth and slots. This not only reduces internal slot resistance and improves heat conduction efficiency but also enhances the motor's peak and continuous performance capabilities. Whether in high temperatures, low temperatures, or other harsh environments, flat wire motors can maintain stable and outstanding performance.

 

Quiet Revolution: Improved NVH Performance

The hair-pin winding motors possesses better rigidity, resulting in superior overall rigidity of the machine. This enhancement not only reduces mechanical noise but also significantly decreases electromagnetic noise. In industrial environments, lower noise translates to a more comfortable work environment and longer equipment lifespan.
