Summary:A stepper motor which coil set including two-terminal coil is disclosed. By setting coils at two terminals of the iron core next to a rotor in every coil set, the magnetic line radiated from the terminal coil is directly operated on the rotor to effectively reduce magnetic flux leakage or attenuation caused by the coil far away from the operation region. Under the condition not change driving energy, through increasing holding torque can improve magnetic energy efficiency. Furthermore, the coil is installed from iron core terminal, it is very convenient. It is not only capable of automatic combination but also allowed to microminiaturize the whole motor size. It is capable of being combined with a circuit board to conveniently utilize the stepper motor.
