Page 7: Section 4: Theory Of Operation
ENDEVCO 2911 INSTRUCTION MANUAL SECTION 4 THEORY OF OPERATION THEORY OF OPERATION The shaker armature has a coil around it inside of a permanent magnetic field. When current is passed through the coil an opposite or attractive magnetic force field is generated depending on the phase of the drive signal. The interaction of the magnetic fields is what causes the armature to move up and down. -
