VIBRATION MOVEMENT ELECTRIC DRIVE WITH REGULATED VIBRATION FUNCTION Russian patent published in 1997 - IPC

FIELD: scanners, testing, measuring and graduating instruments, vibration transport drives and piston movement systems in hydraulic devices. SUBSTANCE: device has two-phase motor which rotor windings are connected in parallel to stator windings; first stator winding is connected to alternating current power supply. In addition device has inverter, analog adder, frequency multiplier, frequency-to-code converter, frequency code generator, n digital adders and n harmonic constituents of law for movement. They include amplitude and phase regulator, filter, counter and frequency multiplier. This results in possibility of generation of multiple harmonic function for alternation of electromagnetic field of final-control motor. Said function is determined by ratio between phases and amplitudes of first and nth oscillation harmonics. EFFECT: increased functional capabilities. 1 tbl, 1 dwg
