Hello
I have a project releated dc motor driver, In this project, I want to start Dc motor with parelel connection of alarm clock's speaker.
And I also made a proteus project, and image is:
I haven't enough knowledge of power electronic, so i cannot decide suitable thyristor, optocoupler, and resistors values.
Motor:
Rated voltage: 12V.
Voltage: DC6V-14V.
No-load rated current: 0.65A or less.
Rated load current: 0.8A ~ 1.2A.
Details: (http://www.aliexpress.com/snapshot/221945512.html)
Tyhristor:BD139 (http://www.datasheetcatalog.org/datasheet/fairchild/BD139.pdf)
Optocoupler: (http://pdf1.alldatasheet.com/datasheet-pdf/view/43371/SHARP/PC817.html)
Are this components suitable for this project? Or have you got any suggestion?
Thanks
