Embodiment Construction

[0175] With reference to the suggestions and methods of the present invention, the original snowplow can be refitted; slightly changing the installation position to adapt to the snowplow is still available. Preferably adopt suggestion of the present invention and way, implement detailed rules on the snowplow machine of mass production.

[0176] Because there is no perfect thing, any product always has many deficiencies and needs to be further improved, just as inventions are endless, so I would like to throw a brick to attract jade.

[0177] No product is perfect, and there are always many deficiencies that need to be further improved. The perfection of human beings' pursuit of invention is never-ending; now there is no need for engines with exhaust emissions, but electric drives are used on small snowplows, which is beneficial to environmental protection; convenient. Therefore, it is convenient to use batteries, especially lithium batteries, on the small-sized snowplow, wit...

Abstract

The invention discloses a brushless motor of an electronic PCB for oblique groove sealing magnetic pieces at openings of a stator. A silicon steel sheet of the stator of the permanent magnet brushlessmotor has nine open grooves; a winding circuit adopts a triangular connection method; a rotor of the permanent magnet brushless motor has eight uniformly distributed square through grooves (m2) whichhave included angles and gradients axially inside; salt bath treatment in a hot liquid containing organic matter during heat treatment; the outside of the rotor of the permanent magnet brushless motor is covered with a thin layer containing indium and graphene through vacuum coating. The oblique groove sealing magnetic pieces at all openings of the nine open grooves of the stator are all pasted and combined with the special electronic PCB covering most parts of the stator rotating circumference.

Description

technical field [0001] The invention relates to a light self-propelled snowplow and lawn mower used in front of office buildings, gardens, sidewalks, etc. The robot lawnmower is used for one-stop multi-machine in the smart garden through the local area network. The brushless motor of the electronic circuit board PCB is used for the stator opening and sealing the oblique magnetic sheet. Background technique [0002] Although it is a good year for auspicious snow, the snow on the road has affected the traffic. The use of large-scale power snowplows on the main road is huge and expensive, and it will be labor-intensive and inefficient if the tactics of crowds are used. Therefore, various light and small snowplows have emerged as the times require. The necessary machine for clearing snow in winter is widely used in parking lots, squares, property communities, gardens, bicycle lanes and many other places. But any product is not perfect, and there are always many deficiencies th...
