Description
103H7123 is 2-phase Stepping Motor ( Nema 23, 56mm sq. ). A stepper motor, also known as a stepping motor, is an electromechanical device that converts electrical pulses into precise mechanical movement. Unlike traditional motors that rotate continuously when power is applied, a stepper motor moves in discrete steps or increments. This makes them particularly useful in applications that require accurate positioning and control.
Key features of stepper motors include:
1. Step Angle: Stepper motors are characterized by their step angle, which is the angle the motor shaft rotates with each input pulse. Common step angles are 1.8 degrees (200 steps per revolution) and 0.9 degrees (400 steps per revolution). There are also motors with finer step angles for more precise control.
2. Control: Stepper motors are controlled using a sequence of electrical pulses sent to their coils. The number of pulses and their timing determine the motor’s position and speed. The motor moves incrementally in response to each pulse.
