DO PHYSICS ONLINE MOTORS AND GENERATORS ... If the load becomes too large causing the armature to rotate slowly or stop, then large currents through the coil will cause unwanted heating effects and damage the motor. When motors are turned on, there will be large coil currents unless there is some protection mechanism.
Guide to Choosing Generator to Motor Size . Some Notes for Sizing Generators. Too small a generator will cause voltage fluctuations and damage to the generator or equipment windings. Too large a generator will cause engine to glaze and carbon up, due to engine loading. Rule of Thumb.

In a generator, mechanical energy is converted into electrical energy while the opposite occurs in the electric motor. The electricity produced by most generators is in the form of alternating current. In general, AC generators, motors and other electrical equipment are simpler, cheaper and more reliable than their DC counterparts.
