The PIC16F877A singlechip is adopted, so that the singlechip-based permanent magnetic brushless direct-current motor control system has the advantages of simple structure, running reliability, convenience in maintenance and high speed-regulating characteristic; moreover, a feedback device is simple, and the output torque is high, so that a motor and an inverter can be applied more fully.
Description
Technical field
The present invention relates to a kind of SCM Based permanent magnetic brushless DC motor control system.
Background technology
Since the nineties in 20th century, development along with the raising of people's living standard and modern production, office automation, the equipment such as household electrical appliance, industrial robot all more and more trends towards high efficiency, miniaturization and high-intelligentization, as the important component part of executive component, motor must have that precision is high, speed is fast, the efficiency high.Brushless DC motor is to grow up on the basis of brush DC motors.Since brush DC motors occurred from the forties in 19th century, the good torque control characteristic with it, within the quite a long time always at the motion control field dominate.But it is a deadly defect of current motor that mechanical contact point brush commutator is arranged always, it has reduced the reliability of system, has limited its use in a lot of occasions.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of SCM Based permanent magnetic brushless DC motor control system, it is simple in structure, reliable, easy to maintenance, possesses good governor control characteristics, and feedback device is simple, the output torque is large, can make motor and inverter be applied more fully.
For addressing the above problem, the present invention adopts following technical scheme: a kind of SCM Based permanent magnetic brushless DC motor control system, comprise motor, optical disc encoding device, extended menory, single-chip microcomputer, current detector and drive amplification device, described motor, optical disc encoding device, single-chip microcomputer and drive amplification device are connected successively.
As preferably, described current detector is arranged between single-chip microcomputer and drive amplification device.
As preferably, described extended menory is connected with single-chip microcomputer separately, and extended menory is not connected with other modules.
As preferably, described motor is DC motor.
As preferably, described single-chip microcomputer is PIC16F877A.
The beneficial effect that the present invention is based on the permanent magnetic brushless DC motor control system of single-chip microcomputer is: because described SCM Based permanent magnetic brushless DC motor control system has adopted the PIC16F877A single-chip microcomputer, it is simple in structure, reliable, easy to maintenance, possesses good governor control characteristics, and feedback device is simple, the output torque is large, can make motor and inverter be applied more fully.
