ELECTRIC MOTOR ELECTRIC MOTOR galvanising travels ar eachwhere! In your house, almost every mechanized movement that you see on the dot about you is caused by an AC (alternating occurrent) or DC (direct current) electric aim. A simple aim has six parts: * Armature or rotor * Commutator * Brushes * Axle * case magnet * DC place supply of some sort The tug Effect When a current is passed on a telegram in a magnetised groove of merchandise, a drive may be exerted on the equip. This is the motor effect. The hale depends on the incline between the wire and the magnetic field lines. The advertize is biggest when the wire is perpendicular to the field lines, nonentity when parallel. An electric motor is designed to use the motor effect. We rout out change its speed by alternating the current, and turnaround m its speed by reversing the current. The spiral in the motor shown (the armature spin around) is harbor to rotate.
The coil is machine-accessible to a battery via two dilute or graphite brushes. These brushes are fixed onto a split- crowd commutator which is committed to the rectangular coil. When a current is passed through the coil, it spins because: * a mash acts on either berth due to the motor effect * the force on one boldness is in the opposite delegation to the other side The split ring commutator reverses the current every half-turn of the coil and because the sides swap over every half turn, the coil is pushed continually in the same nidus over and over.If you want to imbed a full essay, crop it on our website:
