The window motor has an internal thermal breaker in it which opens to prevent the motor from burning out. It appears that you have the motor attached directly to the pivot of the arm. This will place a large load on the motor. When the ball is added, the motor stalls, and the internal breaker trips.
Try using a different motor, and using a gear/chain/belt reduction before the arm.
