How 3 Phase Electric Motors Work
How 3 phases can supply 230 and 415v? How about the peak power rating of each motor? How about the size in diameter of each phase? These are only some of the questions one may ask in relation to a discussion about electric motors.
To answer these queries, you must first understand how electric motors work. It is quite a simple process, as most electric motors work on the same principle of rotation (i.e.) rotation of a shaft with no external force acting on it. The motor uses its own gravitational pull on the shaft as well as its own momentum to rotate. How can such motors work?
Let’s look at another situation. Suppose a car has an electric motor attached to the engine. The motor provides all the energy needed to propel the car forward and speed it up. Now let us imagine that the car slows down. The electric motor is now considered a de-motivating device because it has no chance of providing the necessary force to move the car forward any faster.
How do you determine the motor’s potentiality for supplying torque? Well, you need a way to measure the force that the motor supplies to the shaft at different rotations. In fact, there are three types of rotors that may be used to provide this measurement, namely: rotors with one complete spiral wound around the motor shaft; two complete spirals around the shaft, and a single spiral wound around the shaft. If you put two sets of spirals of the same size around the motor shaft, you can determine the maximum torque that the motor can provide. The size of the motor is inversely proportional to the size of the radius of curvature of the rotor’s path.
How 3-phase electric motors work? When an AC electric motor becomes over-torqued, the inside magnetic field around the magnets begins to cause some sort of imbalance. This causes the flow of electricity to slow down or even to stop completely. This behavior is caused by the magnetic field that remains constant, but the electrical current begins to change.
How 3-phase electric motors work, then, is for the electric motor to begin reversing direction and moving the vehicle in the opposite direction when it receives excess electricity. To keep the motor turning, the flow of current needs to be turned on until the desired torque is reached. The reason why this happens is because the magnetic field continues to create an imbalance in the opposite axis. It pushes the motor to the right and keeps it going, while turning the electric motors left.
How 3-phase motors work, then, also has something to do with the constant rotation of the motor shaft. In order to start the motor turning, the small solenoid valve that is in the center of the motor needs to be opened. Once the valve is open, then the electric current flows into the motor. Because the motor is always in a state of dynamic tension, the engine does not have to work as hard to produce torque. Since the motor is always going to be turning, the small solenoid will close before the next revolution of the wheel takes place.
How 3-phase electric motors work is not simply a scientific fact. It is something that has been demonstrated time and again in everyday situations. While the explanation is not always scientific, it is true. It is also true that it can help save a significant amount of money in the long run. If your electricity goes out, you won’t be able to operate your air conditioner or heater. If your electric motor stops working, you’ll be unable to drive to work or do anything else.
