Stepper Motor Advantages
- Low cost for control achieved
- High torque at startup and low speeds
- Ruggedness
- Simplicity of construction
- Can operate in an open loop control system
- Low maintenance
- Less likely to stall or slip
- Will work in any environment
- Can be used in robotics in a wide scale.
- High reliability
- The rotation angle of the motor is proportional to the input pulse.
- The motor has full torque at standstill (if the windings are
energized)
- Precise positioning and repeatability of movement since good
stepper motors have an accuracy of 3–5% of a step and this error is
non-cumulative from one step to the next.
- Excellent response to starting/stopping/reversing.
- Very reliable since there are no contact brushes in the motor.
Therefore, the life of the motor is simply dependent on the life of
the bearing.
- The motors response to digital input pulses provides open-loop
control, making the motor simpler and less costly to control.
- It is possible to achieve very low-speed synchronous rotation with
a load that is directly coupled to the shaft.
- A wide range of rotational speeds can be realized as the speed is
proportional to the frequency of the input pulses.
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 and
military 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.
