    The stepper motor linear actuator can roughly be divided into two types according to the principle of the propulsive force in electromagnetic field, variable reluctance and mixed type. The former has the advantages of simple structure and low cost and its shortcoming is that the magnetic force is small, asymmetric and the torque fluctuates greatly. The latter is added with permanent magnet on the basis of the former. Therefore, even in the case of power failure, the permanent magnet can also generate a certain torque and can continue to run a certain distance in a straight line. The existence of permanent magnet can form a larger propulsive force in unit volume compared with reluctance. It can easily complete the micro-step control and has less dependence on the parameter in its control distance. The partitioning technique is usually used in the hybrid motor order to improve the smoothness of the linear motion and reduce the fluctuation caused by propulsive force.
