Stepper Motor is widely used in the field of Robotics where high precision is needed.In this article,I will be explaining about the stepper motor and its importance in a detailed way.
Explanation of Stepper Motor:
The stepper motor is taking electrical energy input in the form of pulses and converting into mechanical energy in the form of revolutions.But,by changing no. of pulses of electrical energy to motor (or) by changing rate of pulses of electrical energy input to the motor,the speed of the stepper motor can be changed.
Because of presence of inertia effect of moving parts,even though power supply is stopped to the motor,it is not possible to stop the motor axis immediately.Hence,the tool is travelling some more distance and therefore accuracy of the components produced is poor.i.e. The positional accuracy of the machine tool will become poor.
This is the complete explanation of stepper motor in detailed.There is an advanced of a stepper motor i.e. servo motor which will work much effectively than it and can be used in various installations.
