Operating Principle
Our stepper motor is made up of rotor and stator winding magnet coil. A certain electric current goes through the stator winding timely, then produces a rotating magnetic field within the motor. Under the action of magnetic suction, the rotor will follow this creates a rotating magnetic field, the stator and rotor flux in each chain, produce rotary torque output.
