Stepper motor went through a process from scratch, from the beginning of research and development stage, to turn to finished product stage, and then develop a mature business, achieve a higher level in terms of technology. This development process, in that the motor has been rapid development at the same time, also show a lot of deficiencies in the motor, such as there is disadvantage in terms of control technology. Stepper motor is a kind of special motor for control, can't directly to the dc or ac power, at the time of use must be driven by a dedicated power drive. Especially in the early days, microelectronics technology, computer technology has not been very good development, also cannot be used in motor control, step motor controller of the pulse signal generator is completely implemented by hardware, the control system USES a separate components or integrated circuit of the control loop. This control system, not only in use when debugging is very complex, at the time of use also need to consume a large number of components, and finalize the design after the change control system must be redesigned circuit. Although early step motor in control of technology there are many disadvantages, but with the development of computer technology and other technology, its disadvantages have gradually eliminate, now what kind of motor, many disadvantages are already gone. 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.
