Abstract
The present invention discloses a control method for a multi-phase winding deflection scanning device, comprising: defining a rectangular coordinate system where deflection scanning tracks are located; sequentially decomposing the deflection scanning tracks into finite point rectangular coordinate data; translating the rectangular coordinate data into corresponding point resultant exciting current data; decomposing the resultant exciting current data into n-phase winding exciting current data; and translating the n-phase winding exciting current data into corresponding n-phase control instruction electrical signals and outputting same to a drive power supply, amplifying the output electrical signals by the drive power supply and providing same for the multi-phase winding deflection scanning device as exciting current.
