1. Hybrid linear stepper motors overview
The Hybrid linear stepper motor, is one of the linear motor control products, which is rotated by the magnetic rotor iron core through the interaction with the pulse electromagnetic field generated by the stator. The screw -step motor transforms the rotation motion inside the motor into a linear movement.

7. Factors to consider for model selection
The load of the system includes static load and dynamic load, and often the size of the load determines the basic size of the motor.
Static load: the maximum thrust that can withstand in the static state of the screw.
Dynamic load: The screw is in the state of motion to bear the maximum thrust.
- The running speed of the motor
The running speed of the linear motor is closely related to the guide of the screw, and a screw rotation is rotated. You should choose a screw with a small guide at low speed, and a larger screw should be selected at high speed.
- The accuracy needed for the application
Screw precision: Generally, the screw accuracy is measured by linear accuracy, that is, the error of the actual itinerary and theoretical itinerary after rotating the rotation of the wire.
Repeated positioning accuracy: Repeated positioning accuracy is the accuracy definition of the system that can repeat the specified position, which is an important indicator for the system.
Screw lead: The axial relative movement of the two in the screw and nut of the back gap and the nut. With the increase of working hours, due to wear, the backhalation will increase. The compensation or correction of the back clearance can be achieved by the gap in the gap. When two -way positioning is needed, the back space needs to be noticed.
The installation mechanical structure design, the effective itinerary of the screw, the connection of the motor with movement object etc.
