This article deals about the differences between electric engines and the most appropriate forms for particular tasks.
Basic design of electric engines
Types
Electric motors can be divided into 3 main types: alternating current (AC) motors, direct current (DC) motors, and universal motors. An AC electric motor will not run when supplied with DC current, and a DC motor will not run on AC current; a AC/DC motor will however run on either AC or DC current.
Subtypes:
- AC electric motors: Induction motor (squirrel cage rotor), Induction motor (slip ring rotor), Induction motor (solid core rotor), Shaded pole motor, ...
- DC electric motors: Pancake DC motor, Brushed DC electric motor, Brushless DC electric motor, Stepper DC motor, ...
- AC/DC motors: Universal motor

Requirement of clutch + gearbox ?
- Yes --> types:
- No --> types: variable frequency drive (http://en.wikipedia.org/wiki/Motor_controller#Variable_frequency_drives ), Adjustable speed drive (http://en.wikipedia.org/wiki/Adjustable_speed_drive ), ...
Note; from the article at Howstuffworks about brushless engines, it appears that the rotation speed of the engine (and hence the power output) can be regulated to some extent. It is thus possible that with these engines, no gearbox is necessairily needed in some situations.
==Applications==~
- DC brushed motor (or DC pancake motor): useful for domestic applications (ie powering washing machines, dishwashers)
- AC
