The working principle of discount 1.8 degree stepper motor.
Stepper motor is widely used in control system. It can convert the pulse signal into angular displacement, and can be used as electromagnetic brake wheel, electromagnetic differential, or angular displacement generator, etc. .
Sometimes removed from some old equipment stepper motor this motor is generally not damaged to be used for other purposes, generally need to design their own drive. This paper presents a driver for a stepper motor which is removed from an old type printer made in Japan. This paper first introduces the working principle of the stepper motor, and then introduces the design of its driver's hardware and software.
1. The principle of the stepper motor stepper motor is a four-phase stepper motor, using a single-polarity DC power supply. As long as each phase winding of the stepping motor is energized in a proper time sequence, the stepping motor can be turned.
