Stepper motor in the process of linear stepper motor operation, has its unique works, linear motor, there are two most common ways of circulation: outer loop and the inner loop. The two modes have different characteristics and functions. Firstly, outer circle: the motor cycle is at the end of the cycle through the spiral groove of the surface outside nut or intubation returns back into the circulation between the screw nut. Secondly, inner circle: the inner loop adopts reverser for motor cycle, there are two types of reverser. Linear stepper motor in the process of circulation and screw out of contact sometimes referred to as outer loop; Always keep contact with screw are called inner loop. Motor each loop closed circuit known as the column, each ball lead number included within this loop closed circuit known as the number of turns. So, everyone in the future work to use, to must pay attention to these two kinds of circulation patterns, and according to the characteristics of put to good use.
