Tough and Reliable Stepper Motors

Stepper motors have a number of characteristics that make them very popular devices. These are constant power devices that are used in a number of applications by both professionals and hobbyists alike. Stepper motors are also known as brush-less motors and are more widely chosen over motors with brushes.  Brushes tend to wear out, which means more time replacing and repairing the motors in your applications.

Additional reasons why stepper motors are highly liked is because the location of the winding’s. This makes it easier for heat to dissipate, which keeps the winding’s cooler for any given power outlet. Another reason it is important to choose a stepper motor is the only moving parts that come in contact are the bearings. This results in less wear and tear on your device, which will lead to a longer life span of the stepper motor.

Some stepper motors may even have some extra special features that include something like over-sized bearings. This increases the life length of the application and assures the machine will not fail. The bearings are sealed with high-performance grease which keeps both friction and noise to a minimum.

An additional feature may include a built in thermal sensor, which tells the motor drive when the electronics reach a maximum safe temperature. Although these additional features are helpful, stepper motors hobbyists can bypass these types of add-on’s.

With all the capabilities of stepper motors it is clear to see why they have gained so much popularity. The are quiet and smooth while operating, they are priced very well, and they are designed to last. Take the time to research and browse the different types of stepper motors to find which one will fit your application correctly.
