Title: Armand Lapierre: Innovator in Magnetic Bearing Technology
Introduction
Armand Lapierre is a notable inventor based in Fontaine sous Jouy, France. He has made significant contributions to the field of magnetic bearing technology, holding a total of three patents. His innovative designs have advanced the efficiency and functionality of rotary machines.
Latest Patents
One of Lapierre's latest patents is a device for magnetically suspending a rotor. This device features an axial active magnetic bearing with a main electromagnet coil housed in a stator. It includes load-bearing surfaces that face an armature, which extends perpendicularly to the rotor's axis. Additionally, a device for detecting the axial position of the rotor is integrated with circuits for servo-controlling the current in the main electromagnet coil. A compensation coil is also included, positioned away from the load-bearing surfaces, and carries current in the opposite direction to optimize capacity without magnetic leakage.
Another significant patent is the jacketed active magnetic bearing, designed for rotary machines that operate in contact with process gas within a leaktight enclosure. This design features a magnetic stator protected by a jacket of magnetic anti-corrosion material, which is part of the leaktight enclosure. The detector stator is similarly protected by a non-magnetic anti-corrosion jacket. The bearing armature and detector armature can be made from laminated magnetic material identical to that of the first jacket.
