Latest Patents
Övrebö's latest patents include an electrical machine for submerged applications and an energy conversion system. The invention relates to an electrical machine designed for submerged environments, capable of converting mechanical energy from unidirectional or reciprocating linear or rotational motion into electric energy and vice versa. This system operates entirely submerged in either pure or salt water. The core component of this invention is a multi-pole permanent magnet synchronous machine, which features separately encapsulated stator and rotor, integrated with a mechanical system and power electronics.
Another significant patent is the system for driving elongated electric machines. This complete drive system, referred to as a motor-drive unit, is intended for use in remote locations with limited radial space, such as downhole, narrow tunnels, and pipelines. Given the spatial constraints, the unit is designed in an elongated shape. It consists of several motors connected mechanically in series, along with a smaller number of inverters that drive groups of motors to ensure an even load distribution along the unit's axis. The motor-drive unit is designed to be powered by DC voltage through a cable that can extend several kilometers, incorporating a buck converter for voltage stabilization and a power-line communication module for surface control.
