High speed is the efficiency of the measure of a embroidery machine, embroidery machine speed, however, is controlled by the electric control system and, primarily when big needle embroidery machine switch, electric control system to adjust its speed. Highest speed, minimum speed, long switch needle is used to describe the efficiency of computer embroidery machine three parameters, the highest speed and the lowest speed determines the speed range of the embroidery machine, needle and switch determines the speed down key needle is long, because when grow up in the switch pattern required for needle long, automatically slow to adapt to the taboret action in place. Step progress motor is the highest speed, minimum speed through ascension and change switch long needle embroidery machine of high speed and efficient to implement. Traditional stepper motor driver embroidery computer embroidery machine, high speed is generally set at around 750 r/min, when the needle grew up to 5 mm, due to the limitation of the performance of the stepper motor, electric control system will automatically reduce the spindle speed, to ensure the taboret have enough time to work in place. Step progress motor is controlled by closed-loop type fully, a high speed, strong overload capacity, large output torque, etc, its application in the taboret drive, greatly shorten the time needed for embroidery frame moves back and forth period, this makes the switch in the use of large needle long, embroidery machine spindle can keep high speed work, embroidered box the movement characteristics of more stable, less noise, improve embroidery machine work efficiency. Due to the step progress motor is to integrate the drives and motors, is reducing the installation space, thus it could reduce the cost and the effect of energy conservation and environmental protection. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
