Claim 7:
8. The servo motor drive circuit according to claim 1, wherein the drive signal in each pulse period comprises a pulse invalid level signal and a pulse valid level signal in sequence; and
the first comparing unit is configured to: determine a pulse invalid duration according to a preset duty ratio and the pulse period value, wherein the pulse invalid duration is a product of the pulse period value and a difference between 1 and the preset duty ratio; and send the pulse invalid level signal to the servo motor when the timing duration is less than the pulse invalid duration, and send the pulse valid level signal to the servo motor when the timing duration is greater than or equal to the pulse invalid duration.
