AI Technical Summary
Technical Problem
Single-phase AC motors require a separate starting winding and phase advancement to initiate rotor movement, leading to inefficiencies and increased power consumption.
Method used
A same-pole vector rotation motor design utilizing a stator with electromagnets and a rotor with magnets, where power supply control units intermittently energize electromagnets to generate repulsive magnetic forces, reducing power consumption by half and doubling torque output.
Benefits of technology
The motor achieves reduced power consumption by approximately half and doubled torque output through intermittent power supply and repulsive magnetic forces.

Abstract
To provide a homopolar vector rotary motor.SOLUTION: A homopolar vector rotary motor includes a power supply control unit 10, a stator 20, and a rotor 30. Multiple electromagnets 202 are arranged around the circumference of a stator body 201 of a stator, and are controlled by the power supply control unit to be intermittently powered to generate electromagnetic force. Multiple magnets 302A and 302B are arranged around the circumference of the rotor body 301 of the rotor, and are coaxially inserted into the rotor body and stator body with a central axis 40. When one of the multiple magnets corresponds to the electromagnet, the electromagnet is energized, generating an electromagnetic force equal to the magnetic properties of the corresponding magnet. This mutually repelling magnetic force continues to rotate the rotor body. When the magnet no longer corresponds to the electromagnet as the rotor body rotates, the electromagnet is de-energized, generating no electromagnetic force, and the rotor body continues to rotate due to rotational inertia. When the magnet again corresponds to the electromagnet, the electromagnet is energized again, continuing to rotate.SELECTED DRAWING: Figure 1
