Not only does QPT technology cut the power requirements of electrical motors, it also solves a major industry problem of the size of VFD with a VFD design that is around 20 times smaller than today’s VFDs.

At present, for larger high power, high voltage motors, there is a big box containing the VFD module and the big filters that it needs which often is located at a distance from the motor and connected together via cables. The cables are a problem that companies want to eliminate as they are subject to EMI issues, generate heat losses and are vulnerable to damage in challenging environments.

The new QPT qGaN™ module design is more compact because it uses significantly smaller components so that it can be co-located beside the motor to form a neat, compact integrated solution that just requires the three-phase power in and an optical link for control. No problem-causing cables are required.

This means that these compact, integrated motors can now be built that can handle much larger loads of up to a hundred horsepower using QPT’s new qGaN designs. This makes them ideal for applications such as robotics, factory automation, and industrial pumps especially as this cable-free design now enables power to be re-captured through regenerative braking.
