The linear stepper motor has been made flat instead of round so its motion will be along a straight line instead of rotary.A picture of a linear motor and its amplifier is shown in Fig.11-69,and the basic parts of the linear motor are shown in Fig.11-70.In this diagram you can see the motor consists of a platen and aforcer.The platen is the fixed part of the motor and its length will determine the distance the motor will travel.It has a number of teeth that are like the rotor in a traditional stepper motor except it is passive and is not a permanent magnet.The forcer consists of four pole pieces that each have three teeth.The pitch of each tooth is staggered with respect to the teeth of the platen.It uses mechanical roller bearings or air bearings to ride above the platen on an air gap so that the two never physically come into contact with each other.The magnetic field in the forcer is changed by passing current through its coils.This action causes the next set of teeth to align with the teeth on the platen and causes the forcer to move from tooth to tooth over the platen in linear travel.When the current pattern is reversed,the forcer will reverse its direction of travel.A complete switching cycle consists of four full steps,which moves the forcer the distance of one tooth pitch over the platen.The typical resolution of a linear motor is 12,500 steps per inch,which provides a high degree of resolution.The typical load for a linear motor is low mass that requires high-speed movements.
