A 6-wire stepper motor is similar to a 4-wire configuration with the added feature of a common tap placed between either end of each phase as shown in Figure 2. The commutator rings are connected to the terminal ends of the armature coil but do not directly touch the brushes or the output shaft when the motor is off. The stepper motor is known for its property of converting a train of input pulses (typically square waves) into a precisely defined increment in the shaft’s rotational position. They also operate at 80 – 90% efficiency. The direction of this force is given by Fleming’s right hand rule. The main benefit of servo motors is they provide high levels of torque at high speed – something stepper motors can’t do. However, DC motors are typically more efficient and make better use of their input energy. Working principle of stepping motor. Single Phase Industrial Motors - How do they Work? Themen-Optionen. Stepper motors generally are not available in frame sizes larger than NEMA 34, with most applications falling in the NEMA 17 or NEMA 23 motor sizes. Because of the very high pole count, the motion appears to be continuous. Stepper motors do not rotate automatically as other motors do. Stepper motors work on the principle of electromagnetism. If the stepper motor has a 1.8° step resolution, then in order for shaft to rotate one complete revolution, in full step operation, the stepper motor would need to receive 200 pulses, 360° ÷ 1.8 = 200.
