An engine, or motor, is a machine designed to convert one form of energy into mechanical energy.

A hydraulic motor is one that derives its power from a pressurized fluid. This type of engine can be used to move heavy loads or produce motion.

A pneumatic motor is a machine that converts potential energy in the form of compressed air into mechanical work.

Some motors are powered by potential or kinetic energy, for example some funiculars, gravity plane and ropeway conveyors have used the energy from moving water or rocks.

Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air and others use elastic energy.

Non-thermal motors usually are powered by a chemical reaction, but are not heat engines.

Some engines convert heat from noncombustive processes into mechanical work, they are the non-combusting heat engines.

Combustion engines are heat engines driven by the heat of a combustion process.

Heat engines, including internal combustion engines and external combustion engines burn a fuel to create heat, which then creates a force.
