QPT’s technology not only cuts the power requirements of electrical motors, it can increase power density by up to 20x, enabling much higher power integrated motor drives.

At present, for larger high power, high voltage motors, the motor drive or variable frequency drive (VFD) is often is located at a distance from the motor and connected together via expensive screened cables which can intriduce further losses.

In the cases where a filter needs to be used these are bulky and expensive due to the relatively low frequencies of industrial motor drives.

The new qIPM™ “Intelligent Power Module” is more compact because it uses significantly smaller components due to the higher frequency 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 qIPM as the power stage for industrial motor drives. This makes them ideal for applications such as robotics, factory automation, and industrial pumps especially.
