Hot to operate Spindle Motor with Mitsubishi Driver IC
Many computer CD/DVD ROMs contain a brushless DC motor and a Driver Chip, which controls the speed of motor, stop/start functions and other operations like operating sliding motor and torque controls etc. Is it possible to use that IC (M63016FP or M63022 FP) to operate that motor for my RC Plane? I downloaded datasheets for these ICs and studied although i dont know which pins do i need to run that motor continuesly.

There is a possibility of spindle motor problem. If the spindle motors is short or open then this model dvd players will not turn on from the standby mode. Just replace the spindle motor. And the check. Spindle motor is one in which the cd rotates.Have added the picture of spindle motor for your reference.
You dvd have problem with its spindle motor. Spindle motor is one on which the CD rotates. If the winding of the spindle motor become short this problem can occur. you can see the spindle motor in the center of the mechanism. spindle motor will not cost a lot. Just replace the spindle motor your problem will solved.
The loading motor drive is faulty or the mechanism is jammed. You will have to remove the top cover and check for voltage to the load motor when the open button is pressed, if voltage is present , then motor can be faulty ,jammed. remove , replace or reset.
If there is no voltage press on connectors from the motor drive IC, check voltage here, use a soldering iron to touch up .
if not the drive IC control inputt must receive signal from processor control. If yes then the drive IC can be faulty.
There are different causes as to why your system will not work, The most common failure in DVD/CD players is the spindle motor, If the motor does not spin at the right speed then the pickup lens or laser as its called will not be able to read the TOC(Table of contents). This motor has to spin at a predetermined speed and send its rmp back to the system control for the unit to work. You should consider replacing the Mech assembly as its called it will include the spindle/Stepper motor and gears and the new laser.
If memory serves me well, code H07 means that spindle motor has to be replaced. It is ease enough to test, remove top cover from the unit, load DVD disk, when disk is loaded try to give it clockwise push. If unit starts and works - spindle motor is the problem, if it will not start then spindle motor plus driver IC has to be replaced.
Suggests that the motor regulator IC has problems spinning the disk in a normal way so it will overheat and start to behave in an erratic way - consequentially it may have problems stopping the disk before it ejects.
However, this does not necessarily mean that the IC is bad (far from it), it is just overheating and will usually do so when the spindle motor has oxydized brush contacts - this means that the motor resistance is now higher and that it will not spin at a correct speed with the voltage supplied from the IC.
The electronics will then try to compensate for the speed, but the IC may overheat and start messing up.
Cleaning or replacing the spindle motor might solve the problem, but if the motor can not be replaced because of the unit design and buildup, then this usually calls for the replacement of the entire disk mechanism.
Anyway, this is just one of the possible causes, you might want to try cleaning the laser pickup lens first, but i'm not sure if doing so will make things any better.
This code means that the spindle motor did not come up to speed and the
only way to fix it is to first find out if its the driver servo circuit
thats bad or the spindle motor itself is defective. If you know how to
trouble shoot a motor speed control servo sure you can fix it, But
theres no easy wand waving fix for this unit. Sorry. u may try new spindle motor
Well I have been repairing dvd players a while now and the main problem spots are laser ,spindle motor, laser tracking motor and the biggest culprit and un suspecting one the lens cable .....most of them range from the lens cable to the spindle motor though... the constant movement of the lens in watching a whole movie causes the cable to unknowingly and slowly break and if the spindle motor is defective ,on inserting a dvd the disc spins slowly and you may hear the lens chirping ... so you can check those....
