Stepper motor is a miniature motor, it is encircled by a ring composed of a plurality of steel stator
and a rotor, see fig.. Each steel stator are around a coil; the rotor is a permanent magnet, permanent
magnet center is a nut. Stator coil all always electricity. As long as the change of one coil current
direction, a point of the rotor is turned. When the stator coil in the right order to change the current
direction, forming a rotating magnetic field of the permanent magnet, the rotor rotates in a direction.
If the order is reversed the direction of current change over, so the rotating direction of the rotor will
be upside down. Connect a wire rod drives the nut of the rotor center. Because the spiral rod is
designed into can not rotate, so it can only move in the axial direction, so it is also called linear axis.
End wire rod is a plug, plug and therefore can be retracted or extended, cross-sectional area to
increase or decrease the idle speed actuator bypass inlet passage, until it blocked. Whenever the
current direction change of a coil, rotor around a fixed point of view, called step, a number equal to
360 divided by the stator or coils. The stepping motor rotor step is 15. Accordingly, the screw rod
every move distance is fixed. ECU through the frequency control to replace the coil current
direction, to control the stepper motor moves, thereby regulating the bypass channel cross-sectional
area and flow of air traffic. The air flow in a linear relationship with the step. There is a spring plug
the back screw rod end, see below. Can be used in the plug the elongation direction of the force is
equal to the stepper motor force and spring force; the retracting direction can use force on the plug
is equal to the step force minus the spring force of stepping.
