A Complete Guide to Choose The Best Stepper Motor | PBH

Stepper Motor has the property of converting which converts electrical power into mechanical power.  It is an electromechanical device and is a special type of brushless DC motor which is revolved around with electromagnetic coils outside the motor. Hence, it divides a full rotation into a number of equal steps. It has a plethora of applications, so hire the stepper motor suppliers in India, that provides the best services of stepper motors in the industry. The applications of this machine are plenty and are used in machines that requires continuous movements such as satellites, watches or printers.  These machines are having high accuracy efficiency and has got sensors which records and strategizes feedbacks.

Types of Stepper Motor

• Unipolar Stepper Motor
  This has one independent tap coils which can be magnetized without any dependency. So, the current can run in any directions. However, the main problem with the coil is that only half of each coil is magnetized, so it suffers from reduced magnetic force and reduced torques too. It is easy to install and works in a better pace than the Bipolar motor. It requires large space, so earlier technologies used unipolar motor. But with this technological era, where everything is shrinking, electronic devices tend to use bipolar motors because of the requirement of less space.

• Bipolar Stepper Motor
  They do not have a central tap which divides the solenoid coils. So, it makes the internal coils less complex than the Unipolar motor. It has a single winding per phase which makes it stronger and powerful than a unipolar motor of same weight. Though it has less requirement of wiring space, its operation is a little bit complex and current can be reversed only through H-bridge.

Factors to Consider For a Stepper Motor

• Size of the Motor
  Stepper Motors come in various sizes, from small to big ones. It is obvious that the larger motors would deliver the most powerful services.  The torque of a motor decides its strength. Small motors are used in 3D printers, robots and animatronic applications whereas large ones are used in the industrial applications.

• Step Counts
  Higher step rate is required for torque and speed.  This is another factor to be kept in mind that is the positioning resolution of the cycles. Resolution is expressed in degrees per step, as the step ranges from 4 to 400, the available step count will be 24, 48, 200.

• Gearing
  Gear also positions high resolutions. An 8 revolution will result in 512 step motor. This increases the torque of the motor.

Advantages

Stepper motor has a lot of advantages. Few among them are it has a very low cost for control. It can be easily constructed and is very low maintenance. It can operate in an open loop control system and is less likely to slip. It works in any kind of environment and is a highly reliable machine.

Applications

Commercial applications of Stepper motor are many. It is used in floppy disk drives, flatbed scanners, computer printers, image scanners, compact disks, camera lenses, CNC Machines and lately 3-D printers. It is also used in the field of lasers for precision positioning equipment as linear actuators, linear stages, rotation stages etc. Other uses are for packaging machinery and positioning of valve pilot etc. Even in the medical sector Stepper Motor shows out be a magic as it is used in medical scanners, and found inside digital dental photography and other machines like fluid pumps, respirators etc.

Conclusion

Looking up to the factors, types, advantages of Stepper Motor which are a fundamental part of electronic machines. It is extremely useful as with the help of it a machine can control the movement with the help of Arduino or a PC. Considering the use and advantages of Stepper Motor, hire 2dm 542 stepper motor drive suppliers in India as it is efficient in speed control and gives maximum torque at a very low speed which makes it popular among the electronic gadgets.
