The principle of subversions
Von himaxmotors, 07:59
The subversions of stepper motor control in essential is through controlling the stator winding current to make the synthesis magnetic field in stepper motor internal changing with some requirements, so as to achieve Stepper motor’s sub-step angle. Generally speaking, the magnitude resultant magnetic field’s vector determines the size of the motor rotation torque, the angle between the two adjacent syntheses magnetic field vector determines the step angle size.
Three-phase hybrid stepper motor’ work principle is highly similar to the permanent magnet synchronous servo motor. The permanent magnet rotor used also is high-density characteristics rare earth permanent magnetic materials, Therefore, the induction currents the rotor produced are negligible to the rotor magnetic field. It is equivalent to multi-polar f permanent magnetinduction motor in structure.
