Description of the Invention (I) Field of the Invention The present invention relates to electric power control for sewing drives according to the preamble of the main patent item. Description of related technology Because the sewing machine is a relatively simple machine, part of the electronic control controls operating components such as thread cutters, presser foot plates, etc., and the rest of the main drive is provided in the form of Μ motors to provide control. In the industry, such motors are asynchronous motors with electro-mechanical clutch / brake systems, DC motors K and servo motors. These drives can be operated at a predetermined speed and can be used in asynchronous machines at a predetermined angle. The clutch / brake system is best supplied with a very low voltage below 50 volts, usually 24 volts DC. The clutch or brake coil is controlled by this voltage source in the clock pulse mode. This adjusts the desired gJL speed of the transmission. In this type of power, the servo motor (DC motor or brushless DC motor) is started directly from the line, the line voltage is rectified and temporarily stored with a capacitor of sufficient capacity, and the voltage at the capacitor is formed The so-called intermediate circuit voltage, which then drives the motor through the electronic unit and the sister piece, because the motor is directly operated by the K line voltage, so the adjustment and control line for operating from the line is applied to this control part . In threading technology, the adjustment component is limited to be controlled by an extra low voltage below 50 volts. The reason for this is that not all operations are performed. -3- This paper standard is applicable to the Chinese National Standard (CNS) Λ4 regulations.

V. Description of the invention (less) The operating components and other operating devices can always be designed for money and voltage, and for the operator, it must be guaranteed to prevent Protection against electric shock, however, because the control includes a part for controlling the line voltage of the main drive, a particularly low voltage part must be reliably isolated from the form in which the line voltage K controls itself ( Safety isolation), this means that in addition to maintaining the minimum distance between the wires of the voltage wire, some input and output signals must also provide voltage isolation, regardless of the optical coupling between the two voltage circuits Or change Device. The use of several voltage circuits also requires several power supply devices. For example, a 24 volt power supply that transmits 10 amps of current for a short period (hundreds of milliseconds) provides a service for supplying the adjustment component. Electronic circuits require A 5 volt power supply and a current of about 1 amp, and the electronics that control the main drive on the line voltage side require another voltage between 5 and 15 volts and a current of about 1 amp. Power supply. In sewing technology, the adjustment component is usually controlled by voltage. In order to ensure the reliable function of these components, the voltage must be quite fixed. Therefore, the intermediate voltage cannot be directly used to supply the adjustment component. The intermediate circuit voltage depends on both the line voltage and the operating state of the motor (certainly, during the braking operation, the motor acts as a generator and feeds power back into the intermediate circuit so that its voltage rises because of economic factors, feeding braking energy Returning to the line is excluded from the technology, and instead, when a predetermined voltage is reached, the plug Entering a resistor K transforms the extra braking energy into thermal energy. -4-This paper size applies Chinese National Standard (CNS) Λ4 Regulation (2H) X 29 * 7 Male II!-......: -I-- \ s ^-Hi I—--. i—-..

Savings in volts DC and a fairly expensive voltage source of 10 amps, these adjustment components are designed for this intermediate circuit voltage, so that the current is reduced by the inverse ratio of the increase in voltage with the 24 volt power supply, If the operating conditions that occur in this circuit are also taken into account, the voltage M / ratio of 1: 2 will be used to stabilize the voltage of the adjustment component, and the intermediate circuit voltage will be changed by an A / Measured by the D converter, that is, a few milliseconds, and then a predetermined frequency, the microprocessor can determine a pulse suspension (working) factor so that the adjustment component "sees" an average constant voltage Although they are from the middle-5- (¾Read the notes on the back before filling this page) i. -Β This paper size applies to China National Standards (CNS) Λ4 specifications (210X 297 '»#) Central of the Ministry of Economy印 Printed by the Consumer Goods Cooperative of the Bureau ^ A7 B7 V.
