Advantages And Applications Of Stepper Motor

by Sanjeev Yadav SEO Consultant

In order to divide a full rotation of the wheels of any motor into calculated equal steps, a stepper motor is used. It is a brushless DC motor that carefully moves in discrete steps because of the organized groups of multiple coils around the wheel. These groups of multiple coils are called phases which are energized in sequence to rotate the motor in the desired direction with a single step at a time. A stepper motor also converts the electrical power into mechanical power while simultaneously dividing the full rotation into calculated steps. They are used in a number of precision motion control applications because of their precise positioning and speed control.

Advantages Of A Stepper Motor
Stepper motor and driver are used in a number of industrial machines and other consumer electronic goods because of the precise division of rotation that they perform. There are many other advantages of a stepper motor that make it a popular electromechanical device in most of the machines.

·    A complete and full torque is offered by the stepper motor even when it is placed at a standstill.
·    A majority of stepper motors come with an accuracy of 3% - 5% and so there is least chance of any error.
·    The steps taken by the stepper motor during rotation are precisely positioned and even the repeatability of the movements is strictly checked to ensure that no error takes place while the movement of the motor.
·    As the stepper motors are brushless, the chances of contact of the brushes to the motor are reduced to zero. This elongates the durability of the motor as its life now solely depends on the life of the bearings used inside.
·    There can be a large range of rotational speeds that can be offered by the stepper motor as per the frequency of the input pulses provided.

Applications Of Stepper Motor
A stepper motor is an electromechanical device that is used in a variety of applications for dividing a rotational movement into precise step-wise movement. The various applications of a stepper motor are:
·    Stepper motors are widely used in industrial machines like machine tooling automated production equipment and automotive gauges.
·    They are extensively used in the security industry for the manufacturing of new surveillance products.
·    They are also used in different types of cameras, especially the automatic or digital ones, for the focusing and zooming purposes.
·    A number of medical instruments like scanners and samplers fluid pumps, blood analysis machines, and respirators etc., also have stepper motors fixed inside them.

These were the major advantages and the applications of a stepper motor. You can buy stepper motor and driver from various suppliers and manufacturers at a cost-effective price.
