A repulsion motor is one among single-phase commutator-type motor with a wound rotor and brushes arrangement. It works on the principle of magnetic repulsion between two poles. A repulsion motor will start with repulsion between …
In the last article, we have discussed different types of stepper motors with their constriction and working principles. Now, let us see the characteristics of a stepper motor. The stepper motors characteristics under stationary …
A stepper motor is an electromechanical device that converts a train of input pulses into a train of step movements. In the recent two articles, we have seen permanent magnet and variable reluctance stepper motors. Now let us…
Universal Motor is a single-phase commutator-type motor. It is a special type of motor because either it can be run on a.c. or d.c. supply. The main advantage of this type of motor is that it can be developed in ratings of some f…
Construction of Variable Reluctance Stepper Motor : It is the most basic type of stepper motor . The stator of this motor consists of a three-phase wounded type. It has six salient poles with concentrated windings around each on…
A stepper motor is an electro-mechanical device that actuates a train of step movements of a shaft in response to a train of input pulses. The step movement may be angular or linear. The step movement of the motor is according to…
Principle of Operation of AC Series Motor : An ordinary dc series motor will run in the same direction regardless of the polarity of the supply. The direction of the torque depends upon the relative directions in space of flux a…
