Here also need to prove: the power of restraining coil 4 is far longer than the power of small coil 23, so the inductance of restraining coil 4 also is far longer than the inductance of small coil 23, the resistance of restraining coil 4 is much smaller than the resistance of small coil 23.
According to formula: τ=L/R
Wherein τ is actuation time,
L is a coil inductance,
R is a coil resistance
Can draw: the time of small coil 23 actions is much smaller than the time of break action, so the electromagnetism holding unit is action earlier, promptly drive quiet dish 3 and before guide rod 9 moves to the back-end, iron-core workpiece 22 is locked on the guide rod 9, thereby can guarantee that the distance that Moving plate 2 moves outward is A/2 at pedestal 14.
