Machine comparison
| Machine | Principle | Speed behaviour | Supply | Control | Applications |
|---|---|---|---|---|---|
| DC motor | Current in a magnetic field produces torque | Voltage and load dependent | DC; constant field | Armature voltage | Actuators, traction, small drives |
| Induction motor | Rotating field induces rotor currents | Below synchronous speed in motoring | Three-phase AC | V/f, vector control | Pumps, fans, conveyors |
| Synchronous motor | Rotor field locks to rotating stator field | Synchronous when stable | Three-phase AC + DC field | Frequency and excitation | Large compressors, power-factor correction |
| Transformer | Mutual induction between windings | Static device | AC | Turns ratio, taps | Distribution, isolation, voltage conversion |
