The application discloses a winding structure and a motor adopting the winding structure. The winding structure comprises a plurality of first coils, the plurality of first coils are arranged around an axis of the winding structure, so that the plurality of first coils form at least part of the winding structure; each first coil comprises a plurality of first conductors and a plurality of second conductors. Each first conductor is made of a first material, the first material has electrical conductivity; each second conductor is made of a second material, the second material has magnetic conductivity and electrical conductivity, and the electrical conductivity of the second material is smaller than that of the first material. The plurality of first conductors and the plurality of second conductors are arranged in a preset mode, so that the plurality of first conductors and the plurality of second conductors form a first effective part, a second effective part and an end part of the first coil, and the first effective part and the second effective part are arranged in parallel. Through the above arrangement, the magnetic resistance of the winding structure can be reduced, the magnetic resistance of the whole magnetic circuit can be reduced, and the strength of the air gap magnetic field can be improved.

This invention discloses an automatic switching system, method, and drive circuit for an uninterruptible power supply (UPS) in the field of power electronics. It includes a power module for providing electrical energy to the system; a relay switch unit for controlling the switching of mains power input; an accelerated turn-off unit for accelerating the turn-off of the relay switch unit; a circuit switching unit for switching a high-current drive circuit to a low-current drive circuit after a predetermined delay; and a control module for outputting a high-level signal to control the circuit switching unit to switch the high-current drive circuit to accelerate the closing of the relay switch unit, and outputting a low-level signal to control the accelerated turn-off unit to accelerate the turn-off of the relay switch unit. This invention employs a delayed switching drive design and an accelerated turn-off unit, which significantly simplifies the power supply hardware design, reduces the power requirements of the auxiliary power module, and significantly shortens the relay turn-off time, ensuring the stability and reliability of the UPS during the switching process.

The invention relates to a coating device for applying a flowable medium, in particular a hot-melt adhesive, to a substrate, having a coating valve (13) which has a closure mechanism which opens a metering opening of the coating valve in an open position, so that flowable medium can flow through the metering opening towards the substrate, wherein the closure mechanism can be moved from a closed position, in which it closes the metering opening, into the open position by means of an electromagnet of the coating valve (13), and having a main control unit (17), in particular an SPS (programmable logic controller), which is connected to the coating valve (13) and which provides an electrical output voltage signal in order to control the voltage supply of the electromagnet, in particular periodically, which moves the closure mechanism into the open position and holds it there. The invention is characterized in that a modification unit (19) is arranged between the main control unit (17) and the coating valve (13), which is configured such that it receives, modifies and continues to pass on the output voltage signal of the main control unit (17) to the electromagnet in modified form.
