Research On Brushless DC Motor Without Position Sensor

Masfery electronic engine(BLDCM)control system is an electromechanical electronic system,which combines modern science,such as automobile,energy,electronic products,power theory,navigation technology,computer technology and so on.Based on supporting the traditional high-quality balanced power generator,DC can overcome a series of problems caused by mechanical frequency modulation.It is very common in all aspects of modern society.The development and use of a new type of rare earth permanent walking material will make the main motor brushes more widely.Firstly,it introduces the development history,and the feasibility of DC engine.This study explains the current situation of micro DC automatic comb,and makes it systematically analyze and find the mathematical model,mechanical properties and adjustment.Second,analyze the monitoring principle of sensorless power mechanism.Finally,it discusses the master of hardware design,software and technology DC.
