dynamic E flow GmbH provides high-tech electric machines and solutions for extreme applications. Their capcooltech® motor features direct winding cooling that enables current densities up to 100A/mm2 and overload capacities. Testing shows the capcooltech® design maintains temperatures 40°C lower and heats 10 times faster than conventional cooling. The direct cooling test bench demonstrates capcooltech® motors can achieve maximum power density, temperature resistance, precision, and dynamics even in harsh conditions like vacuum or high temperatures.
