DC motor drive controller used on the precise platform
Abstract：DC motor is popular in all walks in our country with its pretty good
performance since it was invented,. When the DC motor works, due to the presence of
electromagnetic interference and the structure of motor itself, vibration will be
produced. This paper is designed by specific application what DC motor used on
precise platform and based on the features of the DC motor and ARM
Microcontroller, according to the requirements and characteristics of precise platform,
proposed a method of constant current source drive DC motor based on the LM358
chip、IRF740MOS tube in order to guarantee that the DC motor will operate stable
and the motor speed can be controlled in a certain range of error. The hardware design
and software implementation method of this design are also given.
Key words: Direct current motor, precise platform, Constant current source, Single
Chip Microcomputer(SCM).
