Design of brushless DC motor control system
on single-chip computer
Abstract:This text introduces to have no characteristics and development, the vein breadths of brushless the DC motor to adjust soon in have brushless the DC motor to control of applied circumstance, a machine brushless the to ad DC motor to just soon system design method.A machine brushless the a DC motor to djust soon system of hardware design is a textual point contents, the system choose to use are whole with 8051 machines and permit of, have the new function of 8 machines Cygnal C8051 a machine is a core, and the in addition logic the electric circuit constitute the controller, main back track the switch machine an adoption IGBT, the electrical engineering numeral that carried out the PWM bridge type to make the way control.In the design, to the main electric circuit electric current and turned the sub- speed to carry on the examination, carry out the electric current and feedback control turn soons, can make the system satisfy the control request.
