Abstract

The invention relates to the technical field of speed regulation switches, and particularly discloses a brushless motor integrated control switch and an electric tool. The switch is used for adjusting the rotating speed and the rotating direction of a brushless motor and comprises a shell, a push rod assembly, a reversing assembly and a sensing assembly. The push rod assembly comprises a push rod piece body, and the push rod piece body is movably installed on the shell and can reciprocate in the extending direction of the push rod piece body. The reversing assembly comprises a reversing piece body which is rotationally connected to the shell. The sensing assembly is installed in the shell and comprises a push rod piece sensor and a reversing piece sensor, and the push rod piece sensor is used for detecting the displacement of a push rod piece body to control the rotating speed of the brushless motor; the reversing part sensor is used for detecting the position of the reversing part body to control steering of the brushless motor. According to the switch, an operator can effectively control the rotating speed and the rotating direction of the brushless motor, the efficiency of adjusting operation is improved, and the service life of the switch is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of speed control switches, in particular to a brushless motor integrated control switch and an electric tool. Background technique [0002] Brushless motors are used in more and more places because of their low noise, high efficiency, and no dust generation during operation. [0003] However, in the prior art, the brushless motor speed control switch is often designed with a mechanical structure; by changing the connection state of the line and the resistance value of the components, the motor current and voltage are adjusted, and then the speed and steering of the brushless motor are adjusted. Changes and adjustments. The above-mentioned mechanical structure is complex and occupies a large space; during the long-term use of the switch, the parts in contact with each other in the circuit are prone to damage to the components due to excessive friction, which changes the resistance value and makes the speed r...
