  • Unlike a synchronous motor, an asynchronous motor does not require a separate excitation system.

Examples

  • The engineer tested the performance of the new asynchronous motor under varying load conditions.

  • The asynchronous motor is widely used in industrial applications due to its robust construction and reliability.

  • The asynchronous motor operates efficiently in various applications.

  • Many factories rely on asynchronous motors for their machinery.

Morphology

asynchronous + motor

The phrase is compositionally regular: 'asynchronous' simply modifies 'motor', so a B1 learner who knows the words can infer it denotes a motor that does not operate in strict synchrony (i.e., not synchronized). However, the specific technical meaning (that it is an AC/induction motor with rotor currents induced by the stator field) requires electrical-engineering knowledge and is not predictable from the constituents alone, so full understanding is not guaranteed.

Etymology

The term asynchronous motor comes from asynchronous ('not in step') and motor (a machine that turns). Think of two people walking: synchronous people walk exactly together, but an asynchronous person falls a little behind, so in this motor the turning part does not move exactly in step with the magnetic field and the name means it is 'not in step'.
