The invention discloses a novel launching device for entertainment equipment. Permanent magnets with grooves are formed on left and right sides of the bottom of a roller coaster body; the permanent magnets are of an n shape; pulley blocks fixed on a guide rail are also arranged on left and right sides of the bottom of the roller coaster body; a motor which is used for driving a turntable set to rotate is arranged at the bottom of the turntable set; the motor is connected with a belt slot on a side wall of the turntable set through a belt and a belt wheel; a turntable on the right side and the turntable on the left side are integrally fixed with each other; and the turntable on the right side and the turntable on the left side are respectively embedded into the grooves of the corresponding permanent magnets at the top. According to the invention, a variable frequency motor is used for directly driving, so that the relative hydraulic or pneumatic launching noise is reduced; the structure is simple and the space usage is less; a plurality of flywheel energy storage devices are adopted, so that the instantaneous power in use is low and the impact to the power grid is reduced; the control is simple; and the launching speed can be accurately controlled by only precisely controlling the rotating speed of the variable frequency motor.
