Problems solved by technology

[0002] Existing desktop cutting tools are usually driven by motors, and the motors usually use series-excited motors. This type of series-excited motor has a carbon brush structure, and the series-excited motor realizes current commutation through carbon brushes at the same time. One of the bottlenecks of the service life of the tool, and the wear and tear of the carbon brush produces carbon powder, which has caused some pollution to the environment; Transmission direction change and deceleration purpose with the output shaft
However, due to the presence of many transmission parts such as gears in this assembly structure, the transmission efficiency is low, and the overall required assembly space is relatively large, and the assembly structure is relatively complicated; at the same time, the gears are easy to wear parts, and more gear transmission parts The presence of

Abstract

The invention discloses a desk-type cutting tool, and the tool comprises a case. The interior of the case is provided with a brushless motor and a controller, wherein the brushless motor comprises a motor rotating shaft. An external end part of the motor rotating shaft is provided with an output disc in a linkable sleeving manner, and the axis of the motor rotating shaft is perpendicular to the operation surface of the output disc, and passes through the center of the output disc. The periphery of the internal end of the motor rotating shaft is coaxially provided with a rotor core in a sleeving manner, and the peripheral surface of the rotor core is provided with a permanent magnet. The interior of the case is also provided with a stator cooperating with the permanent magnet. The tool is simple and compact in structure, is longer in service life, and is higher in transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of machining equipment, in particular to a desktop cutting tool. Background technique [0002] Existing desktop cutting tools are usually driven by motors, and the motors usually use series-excited motors. This type of series-excited motor has a carbon brush structure, and the series-excited motor realizes current commutation through carbon brushes at the same time. One of the bottlenecks of the service life of the tool, and the wear and tear of the carbon brush produces carbon powder, which has caused some pollution to the environment; The transmission direction change and deceleration purpose between the output shaft and the output shaft. However, due to the presence of many transmission parts such as gears in this assembly structure, the transmission efficiency is low, and the overall required assembly space is relatively large, and the assembly structure is relatively complicated; at the same time, the ...
