VI, vibration plate works
Vibrator of the coil by the AC source rectified by the SCR power supply. When the SCR is a half weeks in the AC conduction is triggered when the pulse of current through the coil, the armature core and the pulse electromagnetic force arises between the mutual attraction, wood troughs are backward. The negative half cycle of the power to withstand the reverse voltage when the thyristor turn-off, no current through the coil weight, the electromagnetic force disappears, the spring plate by means of semi-weekly group in power is the potential energy stored in the armature from the core shells, wood troughs move movement. This trough to the frequency of AC voltage to ~ reciprocating motion. The underside of the trough and the line of action of the exciting force vibrator into 20o angle, so the material in the trough-shaped parabolic micro-jump continuous forward movement. Toss and whereabouts of the material in 1 / 50 seconds, so even when the material seems a continuous movement.
Trough amplitude of the electromagnetic vibrator and the flow through the coil current and the self-feeder vibration frequency ~ related. According to mechanical vibration of the resonant principle, give the natural frequency feeder ~. Adjust the frequency of the electromagnetic exciting force ~ (ie the power frequency) similar to the ratio z =~/~.= 0.85 ~ 0.9, the machine in the low state of the critical work of near-resonant, and thus power consumption is small, work and stability.
