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

The invention relates to an electric drive device with a linearly reciprocating output member for driving automation devices in production, in particular for driving a clamping, gripping, shifting, limiting or positioning device, which comprises an electric rotary motor (2) which has an output shaft (20) which is coupled to a motion screw (31 ) of the device (3) for converting rotational motion into linear motion, the linearly movable output of which is coupled to the output member (110) of the electric device, wherein the output element (110) is linearly reciprocably slidably mounted in the housing (11 ) of the device and is provided with means for coupling to the driven mechanical device (A) and the electric drive device is provided with control electronics for the individual parts of the device. The rotary motor (2) is formed by a BLDC or LSPMSM motor with an external rotor (21 ).

An electric motor is provided. The electric motor can include a first submotor that includes a first stator component and a first rotor component, one of the first stator component and the first rotor component including a plurality of first magnets, and the other of the first stator component and the first rotor component including a plurality of conductive first windings. The electric motor can include a second submotor that includes a second stator component and a second rotor component, one of the second stator component and the second rotor component including a plurality of second magnets, and the other of the second stator component and the second rotor component including a plurality of conductive second windings. At least one of the first windings can be electrically connected in series to at least one of the second windings.

The invention relates to a like-pole vector drive motor comprising a power supply control unit (10), a stator (20), and a rotor (30). The stator (20) has a stator body (201) and several electromagnets (202) arranged along the circumferential side of the stator body (201) and intermittently supplied with current by the power supply control unit (10) to generate electromagnetic forces. Several magnets (302) are arranged along the circumferential side of the rotor body (301) of the rotor (30). The rotor body (301) and the stator body (201) are coaxially penetrated by a central shaft (40).When the rotor body (301) rotates with the central shaft (40) relative to the stator body (201), the power supply control unit (10) supplies a direct current to the electromagnets (202) only when the magnets reach the positions of the electromagnets (202), whereby the electromagnets (202) each generate an electromagnetic force which has the same magnetic polarity as the magnets in order to continuously rotate the rotor by means of the magnetic repulsion force.
