AEG 8000 series tumble dryer T8DEM842E does not rotate.

I have a brought a second hand AEG 8000 series T8DEM842E. It ran one cycle for two hours. Next cycle made screeching sound and then stopped. I heard the motor trying to rotate but the drum did not. I opened the side and released the belt. Motor makes sound but did not rotate. Opened the motor 3 magnets were loose. I cleaned the motor and pasted the magnets back. which rotated fine manually.

Now on any cycle i choose, drum rotates half round seven-eight times with 15sec interval and stops. And after 5-to 8 minutes the machine turns off. No error code. The heating Icon keeps on blinking during this process. Any Idea ?
