SMJ40 - Stepping Motor

Features

  • finer step angles through the control of current.
  • Its step angle is half of the half- step excitation, and quarter of the two-phase excitation.
  • This excitation mode is used to obtain finer step motions or smoother rotations. A W half-step excitation B IWhen using stepper motors 1. The characteristics of stepper motors are affected by their drive circuits. Please disign the circuit carefully. 2. Temperature is also an influential factor. Be sure to operate the stepper moto.

FDK's stepper motors have a claw-pole yoke structure with a cylindrical permanent magnet rotor, as illustrated below. These motors rotate when a rotating magnetic field is generated and when the rotor magnet is synchronized with the rotating magnetic field.
