Short note on Stepper motor

A stepper motor is a type of electric motor that is used in a wide range of applications, from robotics to industrial automation. Unlike traditional motors, which rotate continuously, stepper motors rotate in small, precise steps or increments, making them ideal for applications that require accurate positioning or precise control of movement.

Stepper motors work by using electromagnetic fields to attract and repel the rotor, causing it to rotate one step at a time. They typically have multiple coils that are energized in a specific sequence to produce the desired movement. The number of steps per rotation can vary, depending on the design of the motor, but is typically between 50 and 400 steps per revolution.

Stepper motors come in two basic types: unipolar and bipolar. Unipolar stepper motors have a center-tapped coil and require a simpler driver circuit, making them easier to use but with lower torque. Bipolar stepper motors have no center tap and require more complex driver circuitry, but provide higher torque.

Stepper motors are widely used in a variety of applications, including robotics, 3D printing, CNC machines, and more. They offer precise control and accurate positioning, making them a popular choice in industries where precision and control are critical.
