Abstract

The invention discloses a brushless electric motor speed regulation switch mechanism to resolve the problems of high cost of current controllers, complex structure, large power consumption, serious heat generation or required halt regulation and automatic reset deficiency. The brushless electric motor speed regulation switch mechanism comprises a button I, a frame, a circuit board arranged at theframe, a elastic reset device, a power regulation device and a switch device, wherein the button I is connected with the switch device arranged at the frame, the elastic reset device is arranged between the button I and the frame, and the button I is provided with a contact terminal connected with the power regulation device. The brushless electric motor speed regulation switch mechanism has the advantages of low cost, simple structure, small heat generation, no need of halt regulation, automatic reset in nonuse state, automatic setting of a definite output power and constant power supply or point start power supply for motors.

Description

technical field [0001] The invention relates to a switch mechanism, in particular to a speed-regulating switch mechanism of a brushless motor of 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 during operation. However, for the speed control switch of brushless motors, SCRs cannot be used for speed control. Suitable for the control of brushless motors. If the potentiometer is used for adjustment, it needs to be manually adjusted after the shutdown, which seriously affects the work efficiency, is inconvenient to operate, and cannot be automatically reset, which does not meet the safety regulations of electric tools. Contents of the invention [0003] The purpose of the present invention is to provide a brushless motor speed-regulating switch mechanism for electric tools, which can effectively solve the existing problems of complex structure, inconvenient operation, or...
