Stepper motor is also called the pulse motor, step motor or or stepper motor drives. Recently, along with the electronic technology, control technology and the development of the motor ontology and change, interface between traditional classification of motor is more and more blurred. The author thinks that it is the inevitable trend of electromechanical integration element group. In terms of traditional stepper motor, stepper motor can be simply defined as, according to the input pulse signal, each change a excitation state forward Angle (Or length), if no change excitation state, maintain a certain position and the stillness of the motor. In a broad sense, the stepper motor is a pulse signal control of the brushless dc motor, also can be regarded as to a certain frequency range of the synchronous motor speed control and pulse frequency synchronization. Stepper motor is based on the mechanism of the most basic of electromagnet, the original model originated from 1830 to 1860. To control for the purpose of trying to beginning around 1870, applied to the electrode of argon arc lamp delivery agencies. This is considered to be the initial step motor. Since then, widely used in telephone automatic switching of the stepper motor. Soon afterwards, ships and planes in the absence of ac power is widely used in the independent system. In step motor ontology in the late 1960 s, with the development of permanent magnetic material, a variety of practical step motor arises at the historic moment, while the development of semiconductor technology to promote the application of the stepper motor in many fields. In recent 30 years, stepping motor quickly send yan and mature. From the development trend, the stepper motor can already with dc motor, induction motor and synchronous motor, thus become a basic type of the motor. Research and manufacturing of the step motor in China began in the late 50 s of this century. From the late 50 s to 60 s, mainly is the institutions of higher learning and scientific research institutions to research and use some device or a small amount of product development. These products is given priority to with three-phase reactive stepping motor of the segment structure. In the early 70 s, the stepper motor production and research breakthrough. Besides reflected in the drive for the long-term development of the design, the design of the ontology of reactive stepper motor research and development to a higher level. In the mid 70 s to 80 s for finished product development phase, by continual development of new varieties of high performance motor. Since the mid - 80 - s, due to the precise model of the stepper motor to do a lot of research work, a variety of hybrid stepping motor drive as the products are widely used. 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.
