Operation Principle of the μ-Micro Rotary Motor

The stepping motor is a type of motor which operates by attraction and expulsion of electric magnets with time varying electric pulse signals applied. 

The computer makes operation according to the given data and demanded functions, then sends out the electric pulse signals. After every pulse is sent by the computer, the step motor rotates a definite angle. As the pulse is sent out one by one, the step motor rotates one step by one step. 

When the moving principle of the step motor is applied to a μ-micro rotary motor, the stators are designed to combine many shape of V with shape of Λ linked together that the magnet field is formed. With material Fe-Ni alloy, the micro motor can rotate while driven by the above pulse signals.
