Signals enter the stepper motor drives, stepper motor controller is a kind of to a uniform pulse signals of electronic products. By drive into stepper motor will need strong current signal, drive the stepper motor operation. Stepper motor controller can accurately control stepping motor turned every Angle. Drive that receives the pulse signal, each received a pulse, stepper motor controller will drive around a fixed point of view, this because of this characteristic, stepper motor can be widely used in various industries. The working principle of stepper motor controller and can be used as a poor electromagnetic brake wheel, electromagnetic separator, or angular displacement generator, etc. Step motor has widely application in the control system. Can put the pulse signal into angular displacement. Generally need to drive your own design. Is introduced in this paper from the Japanese detached the old printer designed stepper motor drives. This paper first introduces the working principle of stepper motor, sometimes removed from some old devices of step motor (This kind of motor usually does not damage)To build upon it. Then introduces the software and hardware design of the drive. 1. The working principle of stepper motor using single polarity dc power supply. As long as each phase winding of stepping motor by appropriate timing electricity, the stepper motor stepper motor for the success. Can make the stepper motor step rotation. Figure 1 the four phase reactive stepping motor principle schematic 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.
