Although the stepper motor has been widely used, but the step motor and not like a normal dc motor, ac motor under normal use. It must be driven by double annular pulse signal and power circuit of control system can use. So good with step motor is not easy, it involves the mechanical, electrical, electronic and computer and many other professional knowledge. Stepper motor as the executive element, it is one of the key products of electromechanical integration, widely used in all kinds of automation control system. With the development of microelectronics and computer technology, increasing demand for stepper motor, are used in the field of the national economy. Stepper motor is fixed by a set of winding in motor parts --Driven by the coil in the stator tooth. Generally, a round into a circle of wire is called a solenoid, in the motor, is called winding around the tooth wire, coil, or phase. 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.
