Advantages of Hybrid Stepper Motor
- The advantages of the Hybrid Stepper Motor are as follows:-
- The length of the step is smaller.
- It has greater torque.
- Provides Detent Torque with the de-energized windings.
- Higher efficiency at lower speed.
- Lower stepping rate.
Stepper Motor Applications
- As the stepper motor are digitally controlled using an input pulse, they are suitable for use with computer controlled systems.
- They are used in numeric control of machine tools.
- Used in tape drives, floppy disc drives, printers and electric watches.
- The stepper motor also use in X-Y plotter and robotics.
- It has wide application in textile industries and integrated circuit fabrications.
- The other applications of the Stepper Motor are in spacecrafts launched for scientific explorations of the planets etc.
- These motors also find a variety of commercial, medical applications and also used in the production of science fiction movies.
- Stepper motors of microwatts are used in the wrist watches.
- In the machine tool, the stepper motors with ratings of several tens of kilowatts is used.
