If you have the right resources and materials, finding stepper motors that are suitable for your project can be easy. Hobbyists love brushless motors because they can be used in many different applications. Robotics, CNC machining and other automated mechanical projects are just a few examples of projects that might require a motor.
Because they are reliable, inexpensive, and abundant, step motors are very popular. These motors can be found in many machines if you know where they are. A stepper machine can achieve a complete revolution in between 100 and 400 steps. Each stepper motor's range will also vary, usually between.9 to 3.6 degrees.

Micro-stepping, unipolar and bipolar step motors can be added to make them more powerful. You can find powerful stepper motors in older HP printers, especially LaserJet III printers. They are also free. Hard drives are another component that can be equipped with a step motor, and they are usually found in older computers.
You must remove the step motor, not the spindle that spins your platter drive. You will find the stepper motor on the actuator arm that moves the platter heads. Most people will just buy a new brushless motor and skip disassembling old electronics. Circuit Specialists is a great site to find step motors online.
The site offers a variety of sizes and power ratings. There is no need for you to disassemble any electronics. Do not waste time looking for a stepping motor in an older piece of computer equipment.
