Stepper motor at run time to pass acceleration, uniform speed and slow down the three stages, that is the objective facts, is also unable to change things, especially early motor development, but also will be obvious when using reflects the three stages of operation. But with the progress of science and technology and the development of the industry, the IQ of the running characteristics of this kind of motor have been effectively improve, the operation of the three different stages has been diminishing. Under the joint efforts of scientific and technical workers at home and abroad, through to the stepper motor speed control technology for a lot of research, in addition to a variety of deceleration control mathematical model is established, based on the design and development in addition to a variety of control circuit. Using the control circuit, can effectively change progress running characteristic of motor, in making this kind of motor has a wider application range at the same time, also in terms of motor deceleration do improve effectively, and makes the motor at run time, although now still three stages, but reduction process has been very short, uniform process has been extended effectively. It is because the current step motor movement characteristics have effectively improve the above, so its application scope is more and more widely, application performance is getting better and better. 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.
