Electric Motor Physics

ELECTRIC MOTOR ELECTRIC MOTOR Electric travels atomic number 18 everywhere! In your house, almost every mechanical front man that you see just about you is caused by an AC (alternating new) or DC (direct current) electric motor. A simple motor has 6 parts: * Armature or rotor * Commutator * Brushes * Axle * case magnet * DC power supply of some sort The Motor stamp When a current is passed along a telegram in a magnetic line of merchandise, a drive whitethorn be exerted on the equip. This is the motor effect. The hale depends on the lean between the wire and the magnetic field lines. The force is biggest when the wire is perpendicular to the field lines, nil when parallel. An electric motor is knowing to use the motor effect. We can change its speed by alternating the current, and turnaround time its speed by reversing the current. The scroll in the motor shown (the armature coil) is obligate to rotate.

The coil is machine-accessible to a battery via two alloy or graphite brushes. These brushes atomic number 18 fixed onto a split-ring commutator which is connected to the rectangular coil. When a current is passed through the coil, it spins because: * a force acts on either cheek due to the motor effect * the force on unity nerve is in the opposite committal to the other side The split ring commutator reverses the current every half-turn of the coil and because the sides trade in over every half turn, the coil is pushed continually in the same direction over and over.If you want to establish a full essay, order it on our website: OrderEssay.net
