6.Advantages of hybrid Stepper Motor

The motor is simple in construction, reliable.
At the standstill condition, the motor has full torque.
The motors are less costly.
They require little maintenance.
The stepper motor has an excellent and accurate starting, stopping and reversing response.

   7.Applications of 42mm electric motor:

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.
