Electrical Motor Symbols,
Synchro-Motors and Three-Phase Motors

Electric motors are electromechanical devices whose function is to transform electrical energy into mechanical energy through electromagnetic interactions. There are other engines (generators) that produce electricity by exploiting the mechanical energy, such as alternators and dynamos.
