Described electronic controller includes processing module, rectification module, filtration module, Voltage stabilizing module, over-current detection module and back-EMF determination module, described processing module is directly connected to brushless electric machine, and controlling the start and stop of brushless electric machine, described rectification module, filtration module, Voltage stabilizing module, processing module are sequentially connected electrically；Described over-current detection module electrically connects with processing module；Described back-EMF determination module electrical connection Voltage stabilizing module, processing module, brushless electric machine.
Described brushless electric machine includes stator, cage rotor and motor shaft, and described motor shaft is coaxially provided with inducer.
Described stator is that electromagnetic wire is wrapped on the stalloy of shaping and is integrally forming, and cage rotor is that stalloy enters aluminum strip shaping by aluminum pressure casting inlay.
Described inducer and motor shaft are structure as a whole.
Described drive mechanism includes drive, power transmission shaft and pneumatic means and calms the anger connecting rod, and described drive and power transmission shaft are coaxially connected, and drive and power transmission shaft are calmed the anger with motor shaft and pneumatic means again connection-rod linkage, and described pneumatic means connecting rod of calming the anger is connected with work head.
Described pneumatic means connecting rod of calming the anger is a crank-rocker structure.
Compared with prior art, this device is kept away and has been exerted oneself the use complexity changing carbon brush because of carbon brush abrasion that the connection of traditional carbon brush for electric pick causes, and more keeps away the problem that tradition of having escaped has brush electric pick to burn motor because carbon brush is easy to wear.Described brushless electric machine, he does not have the commutation fairing of traditional brush motor, so not having produced by commutation spark, the motor feels hot, motor is caused to be easily damaged because of heating, traditional brush motor is more because the commutation heating operation characteristic that causes motor is unstable, thus causing the output services of product also unstable.Being provided with wave filter and over-current detector in electronic controller in this is brushless electric pick, run into overload work during product work, over-current detector can play a protective role, it is to avoid the damage of motor or this product.This electric pick, because reversing arrangement do not wanted by motor, so Electromagnetic Interference will not be produced, more serves environmental-protection function.In sum: brushless electric pick applying electronic controller connects the design of brushless electric machine, has lightweight and portable in volume, easy to use, durable in use, and uses the features such as reliable, has vast potential for future development.
