Before I introduce you to the principle of the stepper motor, I introduce the concept of the stepper motor, a micro motor that converts electrical impulses into angular displacements to control rotor rotation. Acting as an actuator in an automatic control device. Each input of a pulse signal, stepper motor, also known as the pulse motor. The stepper motor is used in the peripheral equipment of digital computers, as well as in printers, plotters and disks.
The stepper motor driver consists of a variable frequency pulse signal source, a pulse distributor, and a pulse amplifier, which provides pulse current to the motor windings. The performance of the stepper motor depends on a good combination of motor and drive power. The advantage of stepper motor is no cumulative error, simple structure, easy to use and maintenance, low manufacturing cost, the ability of stepper motor to drive load inertia, suitable for small and medium-sized machine tools and places where speed and accuracy requirements are not high The disadvantage is the efficiency is low, the fever is big, sometimes will be out of step.
