Swing type vibration motor, it is characterized in that, involving vibrations conveyer or vibrating screen classifier cell body (1), frame (2), balanced body (3), passive rocking bar (4), drive crank (5) and swing type vibration motor; Two groups of passive rocking bar (4) middle parts are fixed on frame both sides by rotating shaft interval, often organize passive rocking bar (4) upper end to be rotationally connected with jigging conveyer or vibrating screen classifier trough body (1) side respectively, lower end is rotationally connected with corresponding balanced body (3) respectively; Swing type vibration motor is provided with in frame (2), the armature spindle (6) of swing type vibration motor is connected with mover iron core (7) with keyway by shaft hole matching, drives the stator core (8) of mover iron core (7) reciprocally swinging to be embedded with two groups of stator winding (9) by magnetic resistance minimum principle; Drive crank (5) is also provided with in frame (2) both sides, the drive crank (5) of described both sides is fixed on armature spindle (6) two ends of swing type vibration motor by shaft hole matching and keyway, drive crank (5) upper end and cell body (1) both sides are rotationally connected respectively, and drive crank (5) lower end is rotationally connected with corresponding balanced body (3).
The stroke that mover (7) does oscillating traverse motion relative to stator (8) is 0-11 degree.
Described two groups of stator winding (9) are made up of eight winding coils respectively; Be one group after four series connection, form the winding coil that travels forward, be another group after another four series connection, form motion winding coil backward; Described two groups of stator winding (9) are connected with the IGBT power component of controller respectively, alternately add the DC pulse voltage of pulsewidth and frequency-adjustable under automatic controller program control.
Two groups of winding coils (8) on stator are connected with the IGBT power component of controller respectively, alternately add the DC pulse voltage of pulsewidth and frequency-adjustable under automatic controller program control; Mover iron core (7) and stator core (8) are double-salient-pole structure.
Tool of the present invention has the following advantages:
1. by the application of this oscillating motor, whole jigging conveyer only has two mouthfuls of bearings, and because rotating shaft just swings, the little speed of motion amplitude is low, not Xu Bao Yang in 5 years.Reduce maintenance cost, especially food service industry is realized without oil pollution, there is high use value.
2. owing to adopting supporting controller to drive oscillating motor, make the frequency of jigging conveyer or screening and amplitude easy to adjust, the requirement according to conveying capacity regulates at any time, can reduce frequency and amplitude when not needing, and realizes energy-conservation.
3. adopt compared with this motor drags an eccentric shaft structure with three-phase asynchronous motor in the past and threephase asynchronous machine, when identical frequency and amplitude energy-conservation 50%.
