The name VMA represents a wealth of knowledge and many years of experience in the field of drive technology.
All of our products are made according to our own patented designs, without exception.
Throughout its 29-year history, VMA has registered as many as 20 national and international patents. The products have been perfected by working in cooperation with various universities and pursuing a continuous quality management strategy.
Not only have the products undergone practical stress tests (e.g., on test facilities at Würzburg-Schweinfurt University of Applied Sciences), but theoretical applications have been carefully examined using the finite element method and proprietary simulation programs. In this way, nothing is left to chance.
Our many years of experience and customer-focused approach to solution management make us a highly competent company that is able to provide a fast and professional response.
