Latest Patents:

Neumann's recent patents highlight his expertise in fluid dynamic bearing systems and piezoelectric drive units:

1. Fluid Dynamic Bearing System:

In this invention, Neumann presents a fluid dynamic bearing system designed to support the rotation of a spindle motor. The system comprises a bearing sleeve and a shaft, separated by a bearing gap. Neumann's creativity lies in the use of a counter plate, welded to the bearing sleeve, which features a reduced thickness at its outer edge. This reduction minimizes the vertical gap, preventing air entrapment and facilitating smooth functioning of the bearing system.

2. Piezoelectric Drive Unit:

Neumann's inventive piezoelectric drive unit focuses on generating rotational drive movements. The drive unit consists of a stator, a rotor, and piezoelectric actuators. Notably, an annular gap filled with a fluid medium exists between the stator and the rotor. By utilizing the piezoelectric actuators, which induce radial length changes towards the gap, Neumann harnesses the mechanical energy expended by the actuators to transform it into flow energy within the fluid medium. This flow energy is then transmitted to the rotor, consequently generating a rotating drive movement.
