Title: The Innovations of Josef Zwack

Introduction

Josef Zwack is a notable inventor based in Pocking, Germany. He has made significant contributions to the field of electric machines, holding a total of 2 patents. His work focuses on enhancing the efficiency and functionality of electric machines through innovative designs.

Latest Patents

One of his latest patents is for an electric machine that features a housing accommodating a stator and a rotor, which is rotationally supported about an axis of rotation. This design includes front and rear air inlet openings on the top face, along with an air outlet opening positioned between them. A front/rear air conveying element draws air into the inlet openings, which is then discharged through the outlet during operation. Additionally, a cooler is mounted on the top face of the housing, covering the air inlet and outlet openings in a hood-like manner, allowing discharged air to be fed back to the inlet openings. The cooler also has a partition that extends upward from the top face, and air guiding elements are arranged to facilitate the flow of discharged air.

Another significant patent by Zwack is for a fluid-cooled electric machine. This invention includes a fluid circuit and an integrated pump element that conducts fluid through the circuit as a result of the rotational movement of the electric machine. The design features a stator and a rotor that create a conical air gap, which is flooded with fluid, enhancing the cooling efficiency of the machine.
