Working principle:
1, take following stable state as example.When the stable position below mover 1 is in, magnet steel forms magnetic circuit by magnet case and conducting magnetic column 2.At this moment, under the effect of air-gap field, the conducting magnetic column of stator 2 top and bottom and the conducting magnetic column on mover 1 must align.
2, switch in coil 2-1 and 3-1, the Resultant magnetic field of generation can produce an axial force on mover 1, make mover 1 move upward, and this process is started exactly.When the conducting magnetic column above by the time on the conducting magnetic column on mover 1 and stator 2 aligns, just reach second stable state, mover has been fixed with regard to the position.At this moment outage, the position of mover 1 also no longer changes.
3, in starting process, the axial electromagnetic force that makes progress of generation need to overcome mover gravity, frictional force, the various loads such as detent force.Usually, the electric current that is led to is larger, and the electromagnetic force of generation is larger, more easily starting.But rise move up after, the active force of generation is tens times of starting force, makes mover 1 move upward fast, may break through second stable equilibrium point.If use spacing measure, will produce mechanical impact and noise.
4, in the design, mover owing to having chamfering 2-3 and 3-3, makes on the stable equilibrium point position and moves when first stable position.During starting, owing to having moved on stable equilibrium point, be in more favourable initial position, therefore produce same large starting torque, just do not needed so large electric current.Therefore, after adopting the design, the more efficient more low noise of the work of clutch.
5, when needing mover 1 to get back to first stable position from second top stable position, to switch on equally but change current direction, produce an effect is identical.
