Magnetic drive system with a curved magnetic core

Magnetic Actuation System with Curved Magnetic Cores

This technology is a magnetic actuation control system that utilizes an electromagnet array with curved magnetic cores to minimize the occupied footprint and concentrate magnetic force toward a target location.

Conventional radial electromagnet arrangements occupy significant space, making them difficult to install due to interference issues with medical imaging equipment such as C-arms, and limiting the precision of magnetic field formation.

By forming the tips of the magnetic cores into a curved shape, this technology allows electromagnets to be arranged on a flat plane while still being oriented toward the target, thereby increasing layout flexibility and improving space efficiency. It can be applied to industrial robots and automation systems to enhance output magnetic fields and magnetic force, allowing for increased control and precision in the movement of self-propelled robots.

Key Features:

• An electromagnet array comprising a plurality of electromagnets aligned in a layout space to generate magnetic fields and magnetic forces
• Each electromagnet consists of a magnetic core and a linearly extended electromagnet body with a coil wound around it
• A magnetic core tip extending from the magnetic core to protrude from the electromagnet body
• The magnetic core tip is curved relative to the magnetic core axis and oriented toward the target position
