A stepper motor is an electromechanical device that converts electrical pulses into discrete mechanical movements. Each pulse moves the motor shaft by a fixed angle, called a 'step.' This precise control makes stepper motors ideal for applications requiring accurate positioning, speed regulation, and repeatability. Key Features: Open-loop control (no feedback required) High positioning accuracy Excellent torque at low speeds Low maintenance (brushless design) A stepper driver is an electronic device that sends the necessary current pulses to the stepper motor, enabling it to rotate step-by-step. It translates control signals from a controller (like Arduino, PLC, or microcontroller) into precise motion commands. Functions of a Stepper Driver: Pulse generation and modulation Current control Microstepping (increases resolution and smoothness) Protection
