Stepper motor is has many advantages, in some ways is irreplaceable, and other motor companies there are certain weaknesses, manufacturing enterprise need to continue to efforts in research and development design and production, to some disadvantages to solve some of the motor, further optimize the technology and function of the motor, such as enterprise need to ow to lift motor control. Because early step motor in the control side is single, gradually achieve a wide range of applications, but with the motor on the application of the control requirements of more and more high, companies also need to develop our products in many other aspects of the motor optimization advantages, promote their progress and achieve better development. In stepper motor start or speed up the step pulse change quickly, if not followed by the rotor due to the inertia of the change of the electrical signals have blocked or out of step and a series of bad state, companies will need to motor speed control, in order to prevent this kind of unhealthy phenomenon, so as to improve the working frequency of the motor. Enterprise, therefore, in order to the function of the step motor and run effect on the improvement and further development on product advantages, attract more users to buy their own motor, need through the continuous efforts in the area of r&d design, control of motor speed. 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.
