What type of energy is a motor?

A motor can be used to produce both types of energy, kinetic and potential. It is not in itself a form of energy. It can produce kinetic energy by driving the wheels of a car, or it can produce potential energy by charging the battery in the same car. These are only two of a myriad of examples.

Depends on the type of motor. An electric motor converts electrical energy to magnetic energy to mechanical energy. A combustion engine- like a car, converts chemical energy to heat energy to mechanical energy.
