  • Basic Understanding of Stepper Screw Linear Actuator

    There are several classifications of stepper motors and the stepper screw linear actuator is a part of this classifications. Here we introduce DINGS’ Stepper Screw Linear Actuator in detail. The driving principle of stepper motor The rotor of a stepper motor is a permanent magnet and when an electric current flows through the stator windings, a vector magnetic field is generated in the stator windings. The magnetic field drives the rotor to rotate by an angle such that the magnetic field direction pair of the rotor coincides ...

  • Comparison of Hybrid and Permanent Magnet Linear Stepper Motor

    The average efficiency of hybrid motors is about 65%, while the efficiency of permanent magnet motors is about 25%. The main reasons for the difference in efficiency are the following two reasons :The first reason is that the hybrid motor uses a silicon steel laminated stator assembly (see Figure 1), Compared with the stator assembly formed by stamping and forming of mild steel of permanent magnet motor, the laminated stator of hybrid motor has smaller eddy current loss and the silicon steel material in the laminated structure can reduce hysteresis error ...
