HJK high-voltage electric motors with fin cooling

HJK electric motors offer a unique combination of small dimensions, high output, premium efficiency and easy maintenance. The offer also includes a design intended for use with frequency converters.

Premium technology

HJK motors are manufactured according to the latest development trends and contain first-class quality materials. Thanks to that, they can achieve the same power at a smaller size.

Testing under load

Each HJK motor manufactured has a test under full load included in the base price. Thanks to the load test, we can be sure that the motor will work well in your application.

Customized solution

We design our motors ourselves, so we are prepared to process most customer requirements. The motor can be larger, smaller, longer or shorter. Thanks to this service, substituting the motor in the application is very easy.
