Problems solved by technology

Due to the high-speed rotation, the wear between the relative moving parts of the gasoline engine is accelerated, causing rapid failure of the seals and shortening the service life of the gasoline engine
Due to the high-speed rotation, it may cause damage to gasoline engine components, especially if the rotating parts break and fly outward at high speed, which may pose a threat to the personal safety of the operator.

Abstract

The invention relates to a magneto used by a garden machine, in particular to a magneto capable of limiting speed. The magneto comprises a stator assembly and a rotor assembly, wherein the rotor assembly is arranged on an engine crankshaft through a central taper hole; the stator assembly is arranged on an engine box; a gap of 0.3 to 0.5mm is reserved between the iron core of the stator assembly and the excircle of the rotor assembly; a speed-limiting igniter is arranged in the stator assembly; and one end of the speed-limiting igniter is connected with a power coil in the stator assembly, and the other end of the speed-limiting igniter is connected with an ignition coil in the stator assembly. Compared with the prior art, the magneto has the characteristics of reasonable design, simple structure, accurate control and high use safety of equipment.

Description

technical field [0001] The invention relates to a magneto used in garden machinery, in particular to providing a speed-limiting magneto. Background technique [0002] Under the existing technology, most of the garden machines are hand-held or backpack machines, which are in direct contact with the operator's body during work. As the power of the garden machines, the speed of the general-purpose small gasoline engine can reach more than 15,000 rpm. Among the general-purpose small gasoline engines in the past, due to technical reasons, the maximum speed was seldom limited. Even if the speed limiting device of individual machines, the speed is basically limited by mechanical means. Due to the high-speed rotation, the wear between the relative moving parts of the gasoline engine is accelerated, causing rapid failure of the seals, resulting in shortened service life of the gasoline engine. Due to the high-speed rotation, gasoline engine parts may be damaged, especially the rotat...
