TRACTION MOTOR Meaning and
Definition
-
A traction motor refers to an electric motor specifically designed to provide the necessary power and torque required for propelling vehicles or machines, particularly those used in transportation, such as trains, trams, and electric vehicles. It plays a critical role in converting electrical energy into mechanical energy to drive the wheels or other locomotive components.
Traction motors are typically designed with high power output capabilities to ensure efficient propulsion of the vehicle, with their performance directly impacting factors such as acceleration, top speed, and load-carrying capacity. They provide the required traction and motion, enabling the vehicle to move forward or backward while efficiently utilizing electrical energy.
These motors are predominantly powered by direct current (DC) electricity, as it allows for easy control of speed and torque through variations in the electrical current. However, with advancements in technology, some vehicles also integrate alternating current (AC) traction motors, capable of efficiently driving the vehicle with higher power-to-weight ratios.
Traction motors often employ permanent magnets or electromagnetic coils within their construction to generate the necessary magnetic fields to enable propulsion. The construction and design of traction motors can vary depending on the application and vehicle type, with considerations made for factors such as performance requirements, weight restrictions, and operational conditions.
Etymology of TRACTION MOTOR
The word "traction motor" comes from a combination of two terms: "traction" and "motor".
The term "traction" originally referred to the act of pulling or drawing something, especially in relation to transportation vehicles. It originated from the Latin word "tractio", meaning "a drawing out" or "pulling".
On the other hand, the term "motor" originates from the Latin word "motorem", which means "mover" or "one who imparts motion". It refers to a mechanical device that converts energy into mechanical motion.
Therefore, the term "traction motor" refers to a type of motor specifically designed for providing the necessary pulling force or power to move a vehicle or machinery forward (traction). This term is often used to refer to the electric motors used in locomotives, electric vehicles, and other applications requiring significant pulling power.
