At present, most of the stepper motors used in computer embroidery machines are three-phase hybrid stepper motors, and the use of subdivision drive technology can greatly improve the running quality of stepper motors, reduce torque fluctuations, suppress oscillation, reduce noise, and improve step resolution.
The stepper motor is the high-speed and efficient embroidery machine realized by increasing the maximum speed, the lowest speed and changing the length of the switching needle.
The traditional stepper motor drives the embroidery frame of the computer embroidery machine, the maximum speed is generally set at about 750 rpm, when the needle length is greater than 5mm, due to the performance of the stepper motor, the electronic control system will automatically reduce the spindle speed to ensure that the embroidery frame has enough time to operate in place. Step forward motor is the use of full closed-loop control, has high speed, strong overload capacity, large output torque and other characteristics, which is applied to the embroidery frame drive, greatly shorten the time period required for the embroidery frame to move back and forth, which makes the embroidery machine spindle can maintain high speed work when using a large switching needle length, the motion characteristics of the embroidery frame are more stable, the noise is smaller, and the efficiency of the embroidery machine is improved.
High speed is the standard to measure the efficiency of an embroidery machine, but the speed of the embroidery machine is carried out and controlled by the electronic control system, mainly when the embroidery machine switches large needles, the electronic control system adjusts its speed.
The highest speed, minimum speed, and switching needle length are used to describe the efficiency of the computer embroidery machine three parameters, of which the highest speed and the lowest speed determine the speed range of the embroidery machine.
