A method to motorize bladeset rotation angle of a shutter including the following steps: resetting the bladeset to an origin point position at first when a start instruction is received, rotating the bladeset to a given target angle with respect to the origin point, and calculating a residual angle deviation to continuously rotate the bladeset to the given target angle when an instruction of the given rotation angle is received again during the operation. Further, a device provided to motorize bladeset rotation angle of a shutter includes an input interface for inputting instructions, a sensor for sensing an origin point position of the bladeset, a driver for driving the bladeset to rotate, and a controller for calculating and controlling the operation of the driver according to the origin point position and target angle, such that the bladeset is controlled to be rotated to the required angle.
