IF the receptacle outlet is above 6'8" above the floor, it is typically considered not 'readily accessible' and thus does not need GFCI protection.

However, as stated in other posts regarding motors and so-called 'nuisance tripping', the allowable ground fault for motors is about 1/100th of that which trips a GFCI. Thus, if the motor is tripping a GFCI, the motor/appliance needs to be replaced. Don't remove the GFCI protection, replace the problem - the motor.
