The Stepper Motor
A stepper motor is an electromechanical device, which converts electrical pulses into discrete mechanical movements. The shaft, or spindle, of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. They are the main component enabling a computer to control the motion of any machine tool. More powerful and higher speed servo drive systems are also used for larger systems, however that is a development for any future of a successful company and not necessary to consider at this time.
The principles involved have been known since the development of electrical machinery and steppers have been used for many decades. They are however best suited to digital control and did not become popular until the advent of the digital computer - since when they have appeared in a wide variety of equipment ranging from tiny units in desktop printers to more powerful drives used in computer controlled positioning systems. In one size or another they have become one of the key building blocks in the age of computer-controlled automation.
Steppers are in production in many parts of the world - however, as with all industrial developments, a key part is to have all possible components produced and understood within the structure of the economies concerned.
Four standard sizes have been chosen for manufacture and these will cover the majority of the projected applications - commercial viability will be achieved with the one size required by the Swedish RMT AB Company. This size is very common in further European markets, so this business plan will concentrate on that unit alone leaving the remainder as opportunities for significant future growth of the Company.
