Driving method for solar tracker based on double-screw turntable

The invention discloses a driving method for a solar tracker based on a double-screw turntable. The turntable of the solar tracker is simultaneously driven by a power motor and a precision control motor, and the power motor and the precision control motor are always in a state of driving in opposite rotating directions. According to the driving method, the double-screw turntable is used on the solar tracker, higher power is provided for the turntable of the solar tracker, and gear clearance can be eliminated while precise location is realized through the matching of the two motors, so that the tracking precision of the solar tracker is greatly improved, and the requirement that the solar tracker is applied to a high concentration assembly is met.
