Three-Phase Induction Motors

These flashcards cover key concepts and components related to three-phase induction motors and their applications in industrial settings, particularly in marine environments.

Three-phase induction motor

A motor commonly used in industrial applications, known for being simple, reliable, low-cost, and easy to maintain.

Stator

The stationary part of a three-phase induction motor that houses the winding and supports the rotor.

Rotor

The revolving part of a three-phase induction motor that is turned by the magnetic field created by the stator.

Air gap

The small separation between the stator and rotor, ranging from 0.4 mm to 4 mm depending on the motor's power.

Power distribution

The method by which electrical energy is distributed to different components and systems, such as pumps and fans, within industrial settings.

Electric consumers

Devices or components that draw electrical power from a supply, including pumps and machinery in the engine room.

Power factor

A measure of how effectively electrical power is being converted into useful work output, expressed as a percentage.

Boiler feed pump

A pump used to deliver water to a steam boiler.

Auxiliary blower

A secondary fan or blower that provides ventilation or cooling in addition to primary systems.

Exhaust fan

A fan that removes air from a room, often used to improve air quality and circulation.
