Their rugged construction enables you to use stepper motors in a wide environmental range. Stepper motors are widely used because of their low cost, high reliability, and high torque at low speeds. Since each pulse results in the motor rotating a precise angle - typically 1.8 degrees - you can precisely control the position of the stepper motor without any feedback mechanism.Īs the digital pulses from the controller increase in frequency, the stepping movement converts into a continuous rotation with the velocity of the rotation directly proportional to the frequency of the control pulses. The stepper motor can only receive one pulse and take one step at a time and each step must be the same length. The stepper motor must be sent a separate pulse for each step. Each rotation of a stepper motor is divided into a set number of steps, sometimes as many as 200 steps. A stepper motor is a brushless, synchronous electric motor that converts digital pulses into mechanical shaft rotations.
