Types of Stepper Motor and Its Important Benefits

Stepper motor is basically an electrical motor without brushes. It is quite different from the DC motors. These motors are widely used for a variety of applications including commercial and industrial purposes.

It is one of the most unique varieties of stepper motor that functions in any environment. It is widely used for various purposes as it involves low cost, simple construction, high reliability and better performance at lower speed. It is also known to be the digital version of the electrical motor.

Basic Advantages of the Stepper Motor

Stepper motor has several advantages and some of the most important advantages are mentioned below:

  • If the windings are energized the motor has full power even at standstill position.
  • The input pulse and the rotational angle of the motor are proportional to one another.
  • The stepper motor is considered to be quite reliable as it does not include contact brushes. The durability of the motor depends on the bearing of the motor.
  • These motors are also known to be responsive to various functions included in the motor such as start, reverse and stop.
  • These motors can function in low speed.
  • Different types of rotational speeds can be achieved by using these motors.

Different Types of Stepper Motors

There are fundamentally three varieties of step motors which include the hybrid, variable reluctance and permanent magnet. The hybrid motors are considered to be the most efficient type of motor as it includes the best features of both variable reluctance and the permanent magnet.

The hybrid motors are widely used for a variety of commercial purposes which include CD players, computer disk drives, printers and so forth. These motors are also used for various scientific and industrial applications such as in automated wire bonding and cutting machines, pick and place machines, machine tools, fluid control devices and in the field of robotics.
