Introduction: CDROM Brushless Moter Run
you can run CD rom moter with external power source with the help of moter driver ic datasheet..
Step 1: Moter Driver
if the uper side of ic is like this , this will b moter driver now next step is is ic driver number
Step 2: Ic Moter Driver Number
this is tha ic number
Step 3: Now Find Data Sheet
mostly this ic is use for brush less moter in cd room BD7902CFS
Step 4: Read Tha Data Sheet
page number 12 u can see how to run this moter there are 2 terminal but we use 23 only for standby moter run
Step 5: Connection
you can give up to 2volt for standby moter run to pin number 23
Step 6: For Speed Higher
now same as pin 23 connection to 24 give 3.3 voltage
Step 7: Powering the Ic
give power supply to this board
Step 8: Moter Is Perfect Running
power increase or decrease will speed low and high of moter which connected to vcc of ic given in datasheet
its up to 7,000 RPM now u can make your own quardcopter or what ever you want with out esc..
if you want to make esc with this run with PWM signal wait for my next project with op amp
