These days electrical motors are generally utilized as a part of our everyday life, no matter as small as in our laptop's hard disc till as large as in other electrical machines, for example, fan, refrigerator, washing machine and many more. Electric motors are the sources to drive or direct any equipment with mechanical perspective. This paper mainly focuses on the application of linear motion motors for the linear movement of image sensor. From the various electrical motors, stepper motor has advantage of micro stepping ability to manoeuvre it as per needed steps. Stepper motor miniaturized scale venturing is finished by pulse width modulation of a varying current. Considering the accuracy of every step is 3% to 5% and error inside the last step can't be collected into ensuing step, the stepper motor has higher position preciseness and sensible repetitive motion make them increasingly attractive for the image sensor applications. In this paper, diverse electric motors are examined and compared to see the benefits of each motor and identify the one that is more suitable to be utilized as a part of the movement of sensor/lens.
