What is a stepper motor and how to control it?
If you are looking to obtain full control over a motor, it is necessary that full winding of the motor is carried out. Stepper motor driver provides the controller to bring in various speeds according to the requirement. Hence, it is necessary that the winding is properly carried out in order to achieve different speeds.
All the step motors run on a four phase current and it requires the controller to turn on the power for each phase individually. The best way to accomplish this particular operation is by using a transistor which will provide the means to switch on and off a particular phase.
In a usual rotation for the motor when it achieves the position of full step, the motor moves by 1.8 degree mechanically and takes about 200 steps to complete one revolution. Stepper motor drive is most utilized in industries where there is use of higher power and need to shift the phase according to the requirement. The motor can also be run at half step where instead of 1.8 degree turn, the motor turns to 0.9 degree mechanically. It takes 100 steps to complete one revolution.
Micro stepping was introduced in the year 1980 to control stepper motor driver. This particular method was made popular by Compumotor. Though this particular process is the most stable form to control a stepper motor, it is usually priced high than half step control and full step control. Usually micro stepping consists of production of two sine waves which create the required increment of steps mechanically and this has provided the name Micro stepping. This has provided a full control of the motor as it has helped them create micro increments to the motor to achieve the required speed. Many industries which required precision work utilize this particular operation to have a complete control of their production.
There are different areas where stepper motor driver is used and completely depends on the specifications provided or created according to a requirement. Many companies are now providing full fledged stepper motor drivers which are easy to control. Thanks to the increasing technology, you can control the motor with the help of a computer where you can feed all the parameters that are necessary for an operation. They are clubbed to the controls which then carry out the signal to the motor to change the course of action.
Well known companies are manufacturing stepper motor driver with various speed ratios. One can look out for the one according to their requirements. Many websites present over the internet provide complete details about different motors that are present in the market. Obtaining the right information will always help a person purchase a quality product from a well known manufacturing company. The company has to be such that it provides a very good after sales assistance. This will help when a problem arises. Make sure you have collected enough data to compare among all and come to a conclusion when purchasing a stepper motor.
