Definition

Noun: A machine that converts electrical energy into mechanical energy, producing motion or rotation. It operates through the interaction between magnetic fields and electric currents.

Usage

The term "electric motor" refers specifically to the complete device that uses electricity to create mechanical force. It is typically used as a standalone noun to identify the type of machine.

Examples

• The electric motor in the fan stopped working, so the room became very hot.
• Modern electric cars are powered by highly efficient electric motors.
• He is learning how to rewind the coil of a small electric motor.

Advanced Usage

• "motor" vs. "electric motor": While "motor" can refer to any prime mover (e.g., gasoline motor), the term "electric motor" specifies the power source, eliminating ambiguity.
  • The factory replaced its old diesel motors with new electric motors to reduce emissions.

Variants and Related Words

• Motor (n): A broader term for a machine that supplies motive power. An electric motor is a type of motor.
• AC motor (n): An electric motor that runs on alternating current.
• DC motor (n): An electric motor that runs on direct current.
• Servomotor (n): A rotary or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration, often using an electric motor as its core.

Synonyms

• Electric drive: A system or unit that uses an electric motor to provide motion.
• Electromechanical actuator: A device that converts electrical energy into mechanical motion, often synonymous in technical contexts.

Related Phrases
