Micro Stepper Motor

Microstepping is a method of controlling stepper motors, typically used to achieve higher resolution or smoother motion at low speeds.
Micro Stepper Motor divides each full step into smaller steps to help smooth out the motor`s rotation, especially at slow speeds.
Microstepping is achieved by using pulse-width modulated (PWM) voltage to control current to the motor windings. The driver sends two voltage sine waves, 90 degrees out of phase, to the motor windings. While current increases in one winding, it decreases in the other winding. This gradual transfer of current results in smoother motion and more consistent torque production than full- or half-step control.
