Will the motor be damaged if it has a capacitor
Unless it has thermal protection/shutdown, it may get damaged. In all these cases it''s the reduction in phase margin by the [increased] cap that''s causing a problem. I won''t get into details on this, because LTI control theory is almost certainly too difficult to grasp [right away] by someone wondering about this too-big-capacitor-damage issue. - Download [PDF]
