How Dc Motors Work

How My Motor Works My motor works be lay down of the fundamental laws of magnetism. The north gat of the magnet attracts the south rod of the magnet be vex they have opposite charges; poles of the same charge allow push each other. This attracting and yucky of the magnets is what allows the motor to run. Inside an floor motor, this attracting and get offling of the magnets allows rotational execution to occur. In assembling this galvanising motor, I actually created an electromagnet by wrapping many loops of fit to the motor shaft and the armature, suspending it in the middle of the field poles, and connecting it to a battery. The field poles takes on the habit of an electromagnet when an voltaic flow tell flows through the wire loops wrapped more or less(prenominal) the bottom piece. And when a current goes through the wire bun of the armature, it also becomes an electromagnet. The armature produces a reversing charismatic field while the charismatic field produced by the field poles remains stationary. There pull up stakes be a half-turn of motion because of the way that magnets attract and repel one another, and then the field of the electromagnet will flip and cause the electromagnet to go through another half-turn rotation.

The purpose of the commutator is to reverse the electric current in the axial rotation each term the coil rotates through half a turn. When the field of the electromagnet flips mighty at the end of each half-turn rotation, the electric motor starts spin around freely. The current from the battery connects to the electric terminals of the m otor; and these electric terminals pass on ! electric power into the commutator through the encounteres, a pair of resign connectors that brush up (must be touching) against the commutator. When the commutator has been assembled into place, the coil will life on rotating in the same direction if electricity flows through the circuit. As seen in the first experiment, the magnetic field passel be flipped just by flipping the battery over, which changes the...If you want to get a full essay, order it on our website: OrderCustomPaper.com
