Stepper motor technology is advantageous in applications where we need to control rotation angles, speed, steps and position. By energizing each phase in sequence, the motor will rotate, one step at a time." [5]. When electrical signal is applied to it, the motor rotates in steps and the speed of rotation depends on the rate at which the electrical signals are applied and the direction of rotation is dependent on the pattern of pulses that is followed. We use our stepper motor circuit. For example, a +5 V system can be isolated from a 120 V system by placing a relay between them. The inner device is called the rotor and has four poles. Introduction to Stepper Motors Part 1: Types of Stepper Motors Hello, my name is Marc McComb, I am a Technical Training Engineer here at Microchip Technology in the Security, Microcontroller and Technology Division. Hybrid stepper motors are named because they use a combination of PM and VR techniques to achieve maximum power in a small package size. Stepper motors are controlled by a driver, which sends the pulses into the motor causing it to turn. Conventionally, stepper motors were always controlled by a series of step signals on each phase, which induced a series of magnetic force on the stator to attract the rotor to a certain position. Stepper Motor can be audibly very noisy at moderate to high speeds and have low output power for size and weight. II. 7. In speed control mode, the input Ref is the desired number of steps per second. A controller is similar to a PLC they store and run programs and send signals to a driver.
