F1 & F2 Electric Motors What You Wanted To Know
Electric motors are everywhere. They are in your blender, your food processor, your cordless screwdriver, and possibly even your scooter. Most common among the electric motors you commonly encounter in day to day interaction with the world are f1 & f2 electric motors. F1 or F2 refers to the presence of ends of shunt fields in a DC motor. So it is safe to say that most of the motors around your home are electric DC motors.
The DC motor, and eventually f1 & f2 electric motors got their start in an invention by a man named Michael Faraday in 1821. The prototype invention was really just wires dipping into a pool of mercury. Inside the pool of mercury, Faraday placed a permanent magnet. Then, when a current was passed through the wire, it rotated around the magnet. This is the form of DC motor you probably saw in a high school class using brine rather than mercury, which is toxic.
Zenobe Gramme, 52 years later, improved on Faraday's invention by accident, actually. Gramme connected what is called a spinning dynamo to another similar unit. The similar unit drove it as a motor. Thus the roots of the f1 & f2 electric motor as you know it were established.
Classically, an f1 & f2 electric motors, or DC motor, has a rotating electromagnet with a pair of poles. The speed of the motors is usually dependent upon the voltage and current flowing the motor coils of the engine. The speed is controlled by and proportional to the voltage flowing through. The classic DC motor can achieve a high torque with low speed, and can usually be found in traction applications.
There are, though, some drawbacks to the basic DC motor. Friction is a major concern since the design requires brushes to rub against the commutator. The friction makes the motor noisy and a higher likelihood of the motor wearing out more quickly. There are solutions in varying DC motor designs, though, that can lessen such problems, but with an increase in engineering.
F1 & F2 electric motors can be found all around your home, your office, and even perhaps your vehicle. They are the most basic of DC motors and have a long history with little change even today in the basic structure. Though they are the dinosaurs of the electric motor world, they still are as useful as ever and show little signs pointing toward extinction any time soon.
