Previously, the editor has introduced in detail the advantages and application range of servo motors. It can be seen that this motor has the characteristics of good high-speed performance, strong overload resistance, smooth low-speed operation, and timely response. And it can be applied to spark machines, manipulators, and other machines. So today we mainly introduce the application of servo motors in industrial sewing machines and its system core!
Application of servo motors in industrial sewing machines:
Based on the performance of industrial sewing machines, our country has proposed a design plan for a permanent magnet synchronous motor control system with DSP as the core. The functions and implementation methods of its key parts were introduced in detail, the circuit schematic was designed, the system software and hardware design and system installation were completed; and various performances of the prototype system were tested. At the same time, the requirements of wide speed range and high positioning accuracy of the servo motor system are also well realized, which also enhances the market competitiveness of the product.
Traditional industrial sewing machines ly use clutch motors for main shaft drive, and the movements during the sewing process are completed by mechanical and manual cooperation. However, there are also shortcomings, such as low efficiency, large size, narrow speed range, and poor position. Difficult to control and low degree of automation.
On the other hand, in traditional industrial sewing machines, because the spindle drive is close to the clutch motor, the servo motor is always running at high speed and consumes power regardless of whether the machine is sewing or not after power is turned on. It cannot realize the operation of the machine when there is sewing action, and there is no sewing. When the brake is applied, the machine will stop, resulting in a large amount of waste of electrical energy.
The system design completes the overall technical plan of the overall electronically controlled sewing machine. It is a key step in completing the design of the electronically controlled sewing machine. The electronic control system mainly includes controllers, drivers, motors, encoders, sensors, electromagnets, etc. parts.
The two cores of the servo motor system are as follows:
When we use a servo motor, of course we must know its structure, system, and performance. Servo means following. The servo motor is expected to follow the position, speed or torque of the motor according to the command signal.
The servo motor system can be divided into two parts: servo driver and servo motor. Small AC servo motors generally use permanent magnet synchronous motors as the power source, and there are also motors that use DC motors as the power source, but they are ly used now.
In the early days, DC motors were used because the torque characteristics of DC motors were better than those of AC motors. And because of the development of modern frequency conversion technology, the torque characteristics of AC motors have been close to the torque characteristics of DC motors. However, DC motors are difficult to maintain, so DC motors are gradually replaced by AC motors.
