Self-lifting motor with steel-coreless stator and inclined winding.

Abstract

This invention refers to a type of electric motor that uses magnetic force to hold the rotor stationary without direct contact. To achieve this, the motor's rotor consists of two permanent magnets with axial magnetization, while the stator consists of two sets of windings, each set containing six coils arranged 60° apart. Each coil is made up of wires inclined to the axis of rotation, and the angle of inclination of the coils in the two sets of windings is opposite. As a result, the motor is capable of simultaneously generating torque to rotate the rotor shaft, axial lift to keep the rotor stable horizontally (thrust), and axial lift to keep the rotor stable vertically (thrust).
